Tatemono IQ is an AI-powered investment analysis platform for Japan real estate. It turns a Japanese property listing into a data-driven financial analysis — cap rate, NOI, rental yield, and market benchmarks — in the investor's own language.
The home page introduces the core value proposition: evaluate Japan property deals faster and with more confidence, without needing to read Japanese or manually model every listing. It highlights the AI analysis engine, PDF and listing import, multilingual output, and the two primary audiences (individual investors and real estate agents serving global clients).

The agents page explains how Tatemono IQ helps real estate agents serve global investors. Agents can generate multilingual, client-ready analysis reports from Japanese listings, manage a property workflow, and deliver professional financial output without manual modelling.
The positioning centres on winning and retaining foreign-investor clients by removing the language and analysis barrier: an agent can hand a prospective buyer a clear, data-backed evaluation in English, Chinese, or Korean.

The investors page explains how Tatemono IQ helps individual and institutional investors evaluate Japan properties. It covers automated financial analysis (cap rate, NOI, yield), market benchmarks drawn from Japanese public data sources, and due-diligence support.
The core promise is speed and confidence for cross-border investors who cannot easily read Japanese listings or model deals by hand — Tatemono IQ standardises the analysis so properties can be compared like-for-like.

type: website
---
Tatemono IQ was founded in 2025 by Charles Parra, whose relationship with Japan dates to the late 1980s (Sharp Electronics USA, with time in Osaka and Nara). The company page tells that founder story and lays out the mission: not to tell investors what to buy, but to give them the clarity to make a decision they can stand behind — organizing the information behind every Japan real estate investment decision so it can be compared honestly.
Tatemono IQ describes itself as the decision-support platform for Japan real estate, with a team spanning New York, Tokyo, and Fukuoka. The name comes from 建物 (tatemono, "building") plus IQ — the intelligence to evaluate it.
Tatemono IQ is operated by Parra PropTech LLC (United States). Tatemono IQ K.K. (タテモノＩＱ株式会社) is a Japanese company incorporated on September 9, 2026, with its head office in Shibuya, Tokyo.

"Lost in Translation" explains the challenge Tatemono IQ exists to solve: Japan real estate is hard for foreign investors because of language, legal, and cultural barriers. Listings, disclosures, and financial conventions differ from Western markets and are rarely available in other languages.
The page frames why an AI analysis layer — not just a translation of a listing, but a structured financial evaluation in the reader's language — is the missing piece for global investors approaching the Japanese market.

This guide walks you through the core workflows you'll use every day as a real estate agent on Tatemono IQ, from adding your first property to sharing investor-ready analysis reports.
## What Is Tatemono IQ?
Tatemono IQ is an AI-powered platform for managing Japanese investment properties and sharing them with international investors. As an agent, you import property listings, run AI analysis, and give investors a polished, multilingual view of each deal, without the manual work of translating spreadsheets or building reports from scratch.
The platform has five main areas accessible from the top navigation bar:
| Section | What it's for |
|---------|--------------|
| **Analyses** | View and manage AI analysis reports for your properties |
| **Properties** | Your property library: add, edit, and organise listings |
| **Lists** | Group properties into curated collections for investors |
| **Teams** | Manage team members, roles, and investor access |
## Add Your First Property
Tatemono IQ gives you three ways to add a property. Choose the method that matches where your listing data lives.
### Option 1: Browser Extension (recommended for online listings)
The browser extension imports a property directly from a Japanese real estate listing website in one click.
1. Install the Tatemono IQ browser extension (see the [Browser Extension Guide](chrome-extension)).
2. Navigate to a supported listing site; SUUMO, Athome, Rakumachi, and 10 others are supported.
3. Open the listing page for the property you want to import.
4. Click the **Tatemono IQ** icon in your browser toolbar.
5. The extension automatically reads the page and shows a preview of the extracted data.
6. Click **Save Property** to add it to your Tatemono IQ workspace.
The import takes a few seconds. Once saved, the property appears in **Properties** and is ready for analysis.
### Option 2: Maisoku PDF Import (for broker sheets)
Use this method when you receive a property as a マイソク (Maisoku) broker sheet in PDF format.
1. Go to **Properties** in the top navigation.
2. Click **Add Property**.
3. On the Property Listing Registration Form, click the upload icon in the top-right corner of the form.
4. Select **Import Maisoku** from the upload options.
5. Drag and drop your PDF into the upload area, or click to browse and select the file.
6. Click **Import Maisoku** to submit. Processing takes 30–120 seconds.
7. You will receive a notification when the import is complete. Review the extracted fields before publishing.
Maisoku import extracts all standard fields plus utilities data (gas, water, sewer) that listing websites often omit.
### Option 3: Manual Entry
For properties not available online or as a PDF, fill in the details yourself.
1. Go to **Properties** → **Add Property**.
2. The **Property Listing Registration Form** opens on the **Basic Info** tab.
3. Fill in the required fields: Property Code, Property Type, Property Status, and Listing Date.
4. Use the tabs across the top to complete additional sections: **Property**, **Management**, **Financial**, **Legal/Tax**, **Media**, and **Admin**.
5. Click **Save Draft** to save your progress, or **Publish** when the record is complete.
## Write an AI Property Description
Once a property is in your workspace, Tatemono IQ can write a professional property description for you using its AI Description Writer.
1. Open the property and click **Edit** (the pencil button in the top-right corner of the Property Details page).
2. On the **Basic Info** tab, scroll to the **Description** field.
3. Click **Generate Description**.
4. The AI generates a description based on the property's data: address, building specs, financials, and more.
5. Review the output in the Description field. If you want a different tone or focus, click **Options** to adjust generation settings, or enable **Refinement Mode** to iteratively improve the draft.
6. When satisfied, click **Save Draft** or **Publish** to save the description.
The description is written in the property's primary language. You can regenerate it at any time by clicking **Generate Description** again.
## Hide the Address from Investors
Some agents share properties with investors before a deal is finalised, and prefer to withhold the exact address until they are ready. The address masking feature replaces the full address with a neighbourhood boundary area on the map for all investors on your team.
1. Open the property and click **Edit**.
2. On the **Basic Info** tab, scroll to the bottom of the address section.
3. Check the box labelled **Hide property address from investors**.
4. Click **Save Draft** or **Publish**.
When this setting is on, investors viewing the property see only the general neighbourhood on the map, not the street address or building number. You can turn it off at any time to reveal the full address.
> **Note:** Address masking requires the property address to resolve to a specific building or plot. If the address is too general, the toggle will be visible but disabled.
## Build Your Team
Tatemono IQ is built for teams. You can invite colleagues (other agents or staff) to your team so they can view, add, and edit properties alongside you.
1. Click **Teams** in the top navigation and select **Team Settings** from the dropdown.
2. In the **Team Members** section, click **+ Invite Member**.
3. Enter the invitee's email address and assign their role (Agent or Member).
4. Click **Send Invitation**. They will receive an email with a link to join your team.
Once they accept, they appear in your Team Members list and can access your property library immediately.
## Invite Investors
Investors on Tatemono IQ have a separate role. They can view properties and analyses you share with them, but cannot edit listings or run new analyses. To invite investors:
1. Open **Teams → Team Settings**.
2. In the **Team Members** section, click **+ Invite Member**.
3. Enter the email address and choose the **Investor** role, then click **Send Invitation**.
When you pick the Investor role, a confirmation dialog reminds you that the assignment is permanent: an investor can never later become an agent or staff member. Confirm and send.
Investors who accept appear in your **Team Members** list with the Investor role. You can manage their access (for example, granting a specific investor the ability to see hidden addresses) by toggling **Show full address to this investor** next to their name in Team Settings.
## Run an AI Analysis
Tatemono IQ offers three types of AI-powered analysis for each property. You can generate a report in any of the five supported languages, regardless of the language the property data is in, making it easy to share Japanese listings with English, Korean, or Chinese-speaking investors.
1. Open the property on the **Property Details** page.
2. Click the **Analysis** button (the chart icon with a dropdown arrow).
3. Choose the type of analysis:
- **AI Analysis**: A narrative summary covering investment potential, risks, location advantages, and market context. Best for first impressions.
- **Proforma Analysis**: Financial projections and returns including gross yield, NOI, and cap rate estimates.
- **Cashflow Projections**: Long-term cashflow modelling with loan scenarios, vacancy assumptions, and exit strategy.
4. In the analysis setup form, set the **Analysis Language** to your investor's preferred language.
5. Click to generate the analysis. An AI Analysis usually takes about a minute.
6. The completed report appears under **View Saved** in the Analysis dropdown.
Previously generated analyses are always available under **View Saved**.
## Export a Maisoku PDF
You can export any property as a Maisoku-format PDF, a structured property sheet ready to share with investors or use in presentations.
1. Open the **Property Details** page for the property you want to export.
2. Click **Maisoku PDF Export** in the top-right action buttons.
3. Select the export language from the **Select Export Language** dialog.
4. Choose a PDF template (Property View, Classic, Investor, Compact, and others are available in your team's Maisoku Export Settings).
5. Click to generate. The PDF downloads automatically when ready.
The exported PDF contains the property's core data, photos, financials, and the AI synopsis if one has been generated.
## Share an Analysis with an Investor
Once an AI Analysis is ready, you can generate a secure share link and send it to a specific investor, even one who isn't yet a member of your team.
1. Open the analysis you want to share (via **Analysis** → **View Saved** from the property page).
2. Click **Share Analysis**.
3. Enter the investor's email address.
4. Optionally add a **Personal Note**, a short message the investor will see when they open the link.
5. Click **Generate Link**, then **Copy Link**.
6. Send the link to the investor by email or any other channel.
The investor receives a read-only view of the analysis. If they don't have a Tatemono IQ account yet, the link guides them through a quick registration before granting access.

Tatemono IQ helps you research, organize, and analyze Japanese real estate investment properties. This guide gets you productive from your first login.
## What Tatemono IQ Does for Investors
Tatemono IQ is a research and analysis platform for Japan real estate. You import property listings you're considering, then run a structured analysis across five decision-making dimensions (Financials, Market, Location, Property Condition, and Legal & Compliance) to build a clear investment picture.
## Your Personal Space vs. Teams
Every account has two workspaces:
- **Personal space**: your private library. Properties you import, analyses you run, and lists you create here are visible only to you.
- **Teams**: shared workspaces created by agents or team admins. When an agent invites you to their team, you gain access to properties, analyses, and shared resources in that team's workspace.
You can belong to multiple teams and use your personal space at the same time.
## What Your List Shows on First Login {#why-you-might-not-see-any-properties}
> **Tatemono IQ does not provide property listings.** Your list starts with one sample property whose analysis is already finished, so you can see a full report before adding your own; beyond that, the platform has no built-in data feed.
To add properties, either import them yourself (see below) or wait for an agent to invite you to a team where properties are already shared.
## Import Your Own Properties
You can add properties two ways:
1. **Browser Extension**: browse a supported listing site (SUUMO, at-home, HOMES, and others), click the extension icon on any listing, and the property is imported into your personal space in seconds.
2. **Maisoku PDF**: upload a Maisoku (マイソク) broker listing sheet to extract property data automatically.
Both methods land properties in your personal space. [Learn how to import →](importing-properties)
## Getting Access from an Agent
When a real estate agent or broker uses Tatemono IQ, they can invite clients to their team. Once you accept an invitation:
- You gain access to properties the agent has added to the shared team workspace.
- You can run analyses on those properties.
- The agent can see your analysis results if team sharing is enabled.
Look for an invitation email, or ask your agent to invite you by email address.
Properties in a team workspace are only visible to you once the agent marks them as **published**. Draft properties the agent is still preparing do not appear in your view. In your personal space, you always see your own properties at every stage, including drafts.
## Run Your Own Analysis
Once you have properties in your workspace, you can run an AI-assisted analysis on any of them. Results are saved to your personal space (or to the team, if the property belongs to a team).
Analyses cover five structured areas called the **5 Decision Layers**: Financials, Market, Location, Property Condition, and Legal & Compliance. Each layer generates a summary and a risk rating.
## Explore the Map View
Every property has a built-in map that gives you location perspective without leaving the platform.
- **41 POI categories**: transit, dining, shopping, schools, medical facilities, and more, plotted on the map so you can read the neighborhood at a glance.
- **Hazard overlays**: six government hazard layers (flood, tsunami, storm surge, internal flooding, landslide, and earthquake) layered directly onto the property location. See [Hazard Risk & Map Layers](hazard-risk-map-layers) for how to read each one.
- **Street View & virtual walking tour**: a ground-level look at the surrounding streets and walking routes to nearby destinations.
- **Walk time to the nearest train station**: the walking route and time from the property to the nearest station, with step-by-step directions.
**Why train proximity matters in Japan:** Station walk time (徒歩分) is one of the strongest drivers of rental demand and resale value in Japanese real estate. Every listing publishes this figure; properties within 10 minutes command a measurable premium. Use the map to judge which line serves the property, since different lines carry very different passenger volumes and rental demand profiles.
## Helpful Starting Points
Once you have properties in your workspace:
- **Investor Profile**: set your investment goals and risk tolerance so analyses are calibrated to your strategy.
- **Ask Aki**: use the built-in AI chatbot to ask questions about a specific property or about Japanese real estate in general.
- **Lists**: create property comparison lists to evaluate multiple options side by side.
- **Follow-Up Q&A**: log questions for your broker, record answers as they come in, and automatically apply responses to the property record so your research stays current.

description: Learn the two ways to import property data into Tatemono IQ: the browser extension for live listings and Maisoku PDF import for broker sheets.
---
Tatemono IQ supports two ways to bring property listing data into your workspace. Both methods extract the same core fields (price, address, building specs, station access, financials) but they work differently depending on your source.
## When to Use Each Method
**Use the Browser Extension when** you find a property on one of the 13 supported Japanese listing sites (SUUMO, Athome, Rakumachi, and others). One click in the extension popup imports the listing directly from the page you're browsing. Best for properties you discover while searching online.
**Use Maisoku PDF Import when** you receive broker listing sheets (マイソク) as PDF files. Upload the PDF, and Tatemono IQ's AI extracts all available fields automatically, including utilities information (gas, water, sewer) that listing sites often omit. Best for off-market properties and broker relationships.
## Side-by-Side Comparison
| | Browser Extension | Maisoku PDF Import |
|---|---|---|
| **Source** | Live listing website | Maisoku-format PDF file |
| **Speed** | Real-time (seconds) | Async processing (30–120 sec) |
| **Supported sources** | 13 listing sites | Any Maisoku-format PDF |
| **Utilities data** | Not available | Gas, water, sewer, hot water |
| **Automation** | Manual (browse + click Import) | Auto-applied to property record |
| **Batch support** | Single property per import | Multi-listing detection included |
Both methods extract core property fields including price, address, building specs, station access, floor area, zoning, and investment metrics.
## Supported Listing Sites
The Browser Extension supports the following Japanese real estate sites:

## Install the Extension
These instructions are for **Google Chrome**, the web browser made by Google, not Internet Explorer, Safari, or other browsers. The extension also works on **Microsoft Edge**. If you do not have Chrome or Edge installed, [download Chrome](https://www.google.com/chrome/) before continuing.
### Install from the Chrome Web Store
This is the easiest way to install, and the extension updates itself automatically; there are no manual steps to maintain.

The Tatemono IQ icon will appear in your browser toolbar, and the extension will keep itself up to date.
### Advanced: manual install (developer builds)
> Most users should install from the Chrome Web Store above. These steps are only needed for development builds or pre-release versions distributed as a ZIP file.
**Download the extension**
Log in to your Tatemono IQ account and go to **Settings → Browser Extension**. Click **Download Extension** to save the ZIP file to your computer.
**Install the extension**
**1. Extract the ZIP file**
Unzip the downloaded file to a permanent folder on your computer. Do not delete this folder after installing; Chrome loads the extension from it each time.
**2. Open the extensions page**
In Chrome, go to `chrome://extensions/`, or in Microsoft Edge, go to `edge://extensions/`.
**3. Enable Developer mode**
Toggle the **Developer mode** switch in the top-right corner of the page.
**4. Load the extension**
Click **Load unpacked** and select the folder you extracted in step 1. The Tatemono IQ icon will appear in your browser toolbar.
**5. Pin the extension**
Click the puzzle-piece icon in the toolbar, find **Tatemono IQ**, and click the pin icon to keep it visible.
## Supported Listing Sites
The extension supports the following 13 Japanese real estate listing sites:
- [Rakumachi](https://www.rakumachi.jp/)
- [Kenbiya](https://www.kenbiya.com/pp0/)
- [RealEstate.co.jp](https://realestate.co.jp/en/forsale)
- [Athome](https://www.athome.co.jp)
- [RALSNET](https://www.rals.co.jp/invest/)
- [F-Takken](https://www.f-takken.com/)
- [Hatomark Site (ハトマークサイト)](https://www.hatomarksite.com/)
- [Fukuoka Baibai](https://www.fukuokabaibai.com/)
- [LIFULL HOME'S 投資](https://toushi.homes.co.jp/)
- [投資アットホーム](https://toushi-athome.jp/)
- [三井のリハウス 投資用](https://pro.mf-realty.jp/)
- [東急リバブル 投資用](https://www.livable.co.jp/fudosan-toushi/)
- [SUUMO](https://suumo.jp/)
## Import a Property
**1.** Navigate to a property listing page on any supported site. Make sure you are on an individual property page (not a search results page).
**2.** The extension automatically detects the page and imports the property data in the background.
**3.** Click the Tatemono IQ icon in your Chrome toolbar to open the popup.
**4.** The popup displays the extracted property data. Review the fields.
**5.** If you are a member of multiple Tatemono IQ teams, select the team you want to import the property into from the **Properties will be saved to the selected team** dropdown.
**6.** Click **Save Property** to save the property to your account. The property will appear in your dashboard within seconds.
**7.** The popup shows a confirmation message once the property is saved.
## What Gets Imported
The extension extracts the following data from supported listing pages:
| Category | Fields |
|----------|--------|
| Location | Prefecture, city, district, full address, postal code, coordinates |
| Station access | Up to 3 nearby stations with line name and walking minutes |
| Property | Type, structure, floor area (m²), land area (m²), facing direction |
| Building | Year built, number of floors, elevator, auto-lock |
| Financial | Asking price, monthly rent, gross yield, management fee, repair reserve |
| Legal | Zoning classification, land rights, fire prevention zone |
Not all fields are available on every site. Fields that cannot be extracted are left blank and can be filled in manually after import.
## Troubleshooting
### Extension not detecting the site
**Symptom:** The popup shows "Unsupported site" or prompts you to navigate to a property page.
**Fix:** Make sure you are on an individual property detail page, not a search results page. The URL usually contains a property ID or code. Refresh the page and try again.
### Fields missing after import
**Symptom:** The imported property is missing price, address, or other fields.
**Cause:** The listing site may have changed its page layout, which can break field extraction.
**Fix:** Use the **Send Feedback** link in the main Tatemono IQ application to submit a support request. Include the property URL and a description of the fields that are missing.
### Listing site DOM change
**Symptom:** The extension detects the site but extracts incorrect or blank data after a site update.
**Fix:** Check for an extension update and install it. If the issue persists, use the **Send Feedback** link in the main Tatemono IQ application to submit a support request.
### Google Translate is active
**Symptom:** Error message: "Google Translate is active and we could not fetch the original page."
**Fix:** Disable Google Translate on the page. Click the translation toolbar at the top of the browser and select **Show original**, then reopen the extension popup.
### Extension not loading / popup won't open
**Symptom:** Clicking the Tatemono IQ extension icon does nothing, or Chrome shows the extension as disabled or crashed.
**Fix:** Open Chrome's extension manager (`chrome://extensions`), find Tatemono IQ, and make sure the toggle is enabled. If the extension is marked as "crashed," try removing it and reinstalling from the Chrome Web Store (see [Install the Extension](#install-the-extension)). If your organisation manages Chrome via policy and has blocked the extension, contact your IT administrator. If the issue persists, use the **Send Feedback** link in the main Tatemono IQ application to submit a support request.

section: importing-properties
description: Learn how to import a property by uploading a Maisoku PDF.
---
Tatemono IQ can read a Maisoku (マイソク) broker listing sheet and automatically populate a property record with the extracted data. Upload a PDF and the system processes it in the background, with no manual data entry required.
## Before you begin
- **File format:** `.pdf` files only
- **File size:** 10 MB or smaller
- **One property per file:** If the PDF contains multiple listings, only the first property will be imported
- **File type:** The PDF must be a text-based Maisoku flyer; scanned image PDFs extract fewer fields
## How to import
1. Open the Properties list at `/app/properties`
2. Click **Import Maisoku** in the toolbar
3. Drag and drop your PDF onto the upload area, or click the area to browse for the file
4. Click **Import Maisoku** to start the import
5. The import runs in the background; you will receive an in-app notification and email when processing is complete
## What gets extracted
The AI reads the following categories of information from the Maisoku PDF:
- **Basic Information**: property name, type, listing code, listing date
- **Location & Transit**: full address, prefecture, up to 3 nearest stations (rail line name, walking or bus time)
- **Building Details**: year built, structure type, total floors, unit floor, layout (e.g., 2LDK), private area (㎡), elevator, auto-lock
- **Financial**: sale price, gross yield, monthly and annual rent, management fees, repair reserve fund
- **Land & Zoning**: land area, land rights type, zoning classification, building coverage ratio, floor area ratio
- **Utilities**: gas type, water supply, sewage system, hot water system
- **Management Company**: management company name, management type, combined management and repair fee
- **Equipment & Facilities**: equipment and appliances, parking type and fee, renovation details, renovation history
- **Agent Information**: agency name, phone number, fax number, real estate license number
After a successful import, the source PDF is saved and attached to the property record. You can access it in the **Property Media** section of the property page. Tatemono IQ also automatically runs background enrichment jobs (POI lookup, hazard assessment, and property synopsis) if the address was extracted. No action is required from you.
## If a field is missing or incorrect
All extracted fields can be edited after import. To update a field:
1. Open the property
2. Click **Edit**
3. Navigate to the relevant section
4. Update the field and save
Fields that were blank after import simply need to be filled in manually. The import does not overwrite data you add later.
## Troubleshooting
### Upload fails immediately
**Likely cause:** The file is not a PDF, exceeds 10 MB, or is corrupted.
**What to do:** Confirm the file is a standard Maisoku PDF under 10 MB and try re-exporting from the source software.
### Import completes but very few fields were extracted
**Likely cause:** Scanned image PDF, unusual layout, or non-Maisoku document.
**What to do:** Use a text-based PDF (not a scanned image) and confirm the file is in standard Maisoku flyer format.
### Some fields are blank after import
**Likely cause:** Non-standard formatting, OCR artifact, or value outside expected range.
**What to do:** Fill the missing fields manually via the property edit form. Check that numeric values such as year built and yield are within typical ranges.

section: properties
description: Master the Properties page: switch between table and gallery views, customize columns, explore the interactive map, and check nearby stations, shops, and walking routes.
---
The Properties page is where every property you import lands, and it's more than a list. It combines a sortable table, a visual gallery, and an interactive map with neighborhood exploration tools built for evaluating Japanese real estate from anywhere in the world.
## Table and Gallery Views
Use the view toggle in the top-right corner of the Properties page to switch between two layouts:
- **Table view** shows properties in a sortable list with customizable columns, best for comparing many properties on specific metrics like price or yield.
- **Gallery view** shows property cards alongside the interactive map, best for exploring locations and getting a visual feel for your portfolio.
Your choice is remembered, so the page opens the way you left it.
## Customizing Table Columns
In table view, click the column selector to show or hide columns. Add the metrics that matter to your strategy: asking price, gross yield, year built, and more. Your column preferences are saved automatically.
## Analysis Counts at a Glance
Properties that already have saved AI analyses show a count:
- **In table view**, the analysis count column shows how many analyses exist for each property. Click the count to jump to all analyses for that property.
- **In gallery view**, property cards display a count badge. Click it to see all analyses for that property, yours and your team members' combined.
- **In the filter panel**, filter by analysis count: show only properties with analyses, without analyses, or with a minimum number. This is a quick way to find properties you haven't evaluated yet.
## Page Size and the Map
The items-per-page control does double duty: it sets how many properties appear in the list *and* how many appear on the map. Increase it to 100 or more (up to a maximum of 500) to see a larger slice of your portfolio mapped at once.
## Navigating the Map
The map displays every property on the current page, and it stays in sync with the list; changing the page or page size updates the markers automatically.
Two map controls help you move around:
1. **Fit to View** zooms the map to show all current markers.
2. **Box zoom** lets you draw a rectangle to zoom into a specific area.
When properties sit close together, they group into **clusters**, numbered circles showing how many properties are inside. Click a cluster to zoom in and separate them.
## The Property Details Panel
Click any property marker to open the details panel. It brings together:
- Location details
- Hazard risk assessment for the site
- Pricing details
- Interactive tools for exploring the neighborhood (covered below)
## Nearby Places
With a property selected, toggle the nearby places buttons to see what's around it:
- **Transit**: train stations and airports
- **Daily Essentials**: convenience stores and supermarkets
- **Dining**: nearby restaurants
Station access and daily convenience are major drivers of rental demand in Japan, so a quick scan of these three layers tells you a lot about a property's tenant appeal.
## Walking Route to the Station
Click the walking route button to find and display the route to the nearest major train station. You'll see the distance, estimated walking time, and the station name with its railway connections, the same 徒歩○分 (minutes on foot) figure Japanese renters look for first.
## Virtual Street Tour
Open the virtual street tour to walk the station route in Google Street View without leaving your desk. The tour advances automatically along the path and pauses at intersections to look left and right, giving you a real sense of the streetscape, hills, and surroundings a tenant would experience daily.
## Working with Property Cards
In gallery view, each card shows the key facts: property code, location, type, units, year built, price, and yield.
- Click the **property code** to open the full details modal.
- Click the **map icon** to highlight that property on the map.
## Starring Properties
Click the star on any property card to add it to your **Starred** list for quick access. Starred properties are automatically collected in a predefined list on the Lists page, a zero-effort shortlist.
For more deliberate organization, use the menu on each property card to add the property to custom lists.
## Next Steps

section: properties
description: Group properties into lists by deal stage, client, or investment strategy, then compare, manage, and run AI analyses across an entire list at once.
---
Lists let you group properties any way that fits how you work: by deal stage, by client, by neighborhood, by investment strategy. Once grouped, you can open a list to work with just those properties, or run an AI analysis across the entire list at once.
## What Lists Are For
A few ways investors and agents use lists:
- **Deal pipeline**: "Researching", "Contacted broker", "Made offer"
- **Client shortlists**: one list per investor client you're advising
- **Strategy buckets**: "Under 5M yen", "Osaka minpaku candidates", "High-yield regional"
- **Comparison sets**: a handful of similar properties you want to rank against each other
A property can belong to multiple lists, so use as many groupings as help you think.
## Create Your First List
1. Open **Lists** from the main navigation.
2. Click **Create List**.
3. Give it a name. That's it. You're ready to start adding properties.
## The Lists Page
All your lists appear as cards on the Lists page, each with an at-a-glance summary. Open any card to see the properties inside, or use the quick actions directly from the card.
## Quick Actions
Each list card carries quick actions so common tasks don't require opening the list:
- **Rename** the list as your pipeline evolves
- **Run an AI analysis** on the whole list
- **Manage** the list's contents
To work with the properties themselves, click **View List**; you'll get the familiar property browsing experience scoped to just that list.
## Adding Properties to a List
From the Properties page, use the menu on any property card to add it to one or more lists. You can add a property to an existing list or create a new list on the spot.
## The Starred List
The star button on property cards feeds a predefined **Starred** list, an instant shortlist that requires no setup. Star properties as you browse, then find them all together on the Lists page. See [Browsing Properties](browsing-properties) for more on starring.
## Analyzing a Whole List
Running an AI analysis at the list level unlocks comparisons you can't do one property at a time, most notably **Cash Flow Ranking**, an analysis type only available for lists. It evaluates every property in the list and ranks them by projected cash flow, so you can see at a glance which deal deserves your attention first.
Start a list analysis from the quick actions on the list card. For the full picture of analysis types and options, see [Running AI Analyses](running-ai-analyses).

title: Hazard Risk & Map Layers

type: documentation
section: properties
description: Read Japan's natural disaster hazard data on any property: six government map layers for flood, tsunami, storm surge, internal flooding, landslide and earthquake, plus the seismic hazard tier and 30-year probability on the property panel.
---
Japan is one of the most hazard-exposed developed countries in the world, and hazard exposure is priced into the market: it affects insurance cost, tenant demand, financing, and resale. Tatemono IQ overlays official Japanese government hazard data directly onto every property's map and summarizes it on the property panel, so you can read a site's disaster risk without leaving the platform or reading a Japanese hazard map by hand.
## The Six Hazard Layers {#the-six-hazard-layers}
Six hazard layers are available. All six are **off by default** and reset each time you load the page, so you turn on the ones relevant to the property you're evaluating.
| Layer | Icon | What it shows |
|---|---|---|
| **Flood** | a house in water | Projected river flooding: inundation depth at the location under the planning scenario. |
| **Tsunami** | a wave | Projected tsunami inundation depth for coastal and estuary locations. |
| **Storm Surge** | a wind swirl | Typhoon-driven sea-level rise pushing water inland. The icon is a wind symbol, not a water one. |
| **Internal Flooding** | heavy rain | 内水 (*naisui*): drainage and sewer backup during heavy rain, which floods areas that no river reaches. Distinct from river flood, and often the more relevant layer for dense urban sites. |
| **Landslide** | a slope with debris | Designated landslide hazard zones: steep-slope failure, ground movement, and debris flow. |
| **Earthquake** | a seismograph trace | Probability of strong ground shaking at the location over the next 30 years. |
The on-screen control is labeled **Earthquake**, while the property panel uses **Seismic** for the same underlying data. They refer to the same thing.
## Using the Map Controls {#using-the-map-controls}
The hazard controls live in the map's property panel. You'll find them in two places:
- On a **property's detail page**, where the panel opens by itself. The map on this page loads on demand: click **Show map** first, and the panel with the hazard controls appears with it.
- On the **Properties list map**, once you click a property marker to open its panel.
There are four controls:
1. **The six layer toggles**: a 3×2 grid of icon buttons. They carry **no printed labels**, so hover a button to see its name in a tooltip, or open the legend, which names every layer you've turned on. Click a button to add that layer to the map; click again to remove it.
2. **Overlay opacity**: a slider controlling how strongly the hazard colors sit over the base map. Turn it down to read street names and building footprints underneath.
3. **Clear all**: removes every active layer at once. It appears in the Hazard Layers header **only once at least one layer is on**, so you won't see it on a fresh panel.
4. **Show legend / Hide legend**: opens and closes the color key described in the next section.
One layer behaves differently: **Earthquake** depends on an external service, and after you turn it on, its button can appear greyed out with an explanatory tooltip if that service is unavailable. The other five layers have no equivalent state.
## Reading the Legend {#reading-the-legend}
Open the legend to see what the colors mean. It lists **one block per layer you've turned on**, each headed by that layer's name, so the legend is also how you confirm which layers are active. Four of the six layers share a single depth scale, described once below.
In the screenshot above, Flood and Earthquake are both active, so the legend shows a depth scale for Flood, a probability scale for Earthquake, and the source line for each. A **Clear all** button sits in the header because at least one layer is on.
**The shared depth scale.** Flood, Tsunami, Storm Surge and Internal Flooding all measure the same thing, expected inundation depth in metres, and share one five-step color ramp:
- 0 – 0.5 m
- 0.5 – 3 m
- 3 – 5 m
- 5 – 10 m
- 10 m +
Depth matters more than the presence of color. Half a metre is a cleanup; three metres puts the entire ground floor underwater and determines whether a ground-floor unit is rentable at all.
**The earthquake probability scale.** The Earthquake layer has its own five-step ramp, and it measures probability rather than depth: the chance of JMA seismic intensity 震度6強 or stronger shaking at that location within 30 years:
- 0 – 0.1%
- 0.1 – 3%
- 3 – 6%
- 6 – 26%
- 26 – 100%
**Landslide shows zones, not depths.** The landslide overlay marks designated hazard **zones**: steep-slope failure, ground movement, and debris flow. The color scale shown under the Landslide heading is the depth scale used by the water-based layers; it does not describe landslide zones and can be ignored for this layer. What matters is whether the property falls inside a marked zone.
## The Property Hazard Panel {#the-property-hazard-panel}
Alongside the map, each property carries a **Natural Disaster Hazard Risk Assessment** section that summarizes all six hazards as cards. Each card shows a colored risk badge, and cards with data expand to show the underlying figures: inundation depth and water retention time for the water hazards, tier and probability for earthquake.
The property above carries a Moderate flood and storm surge reading, no tsunami, landslide or internal flooding exposure, and a High seismic reading, with an Overall Risk of Low. That combination is explained in [What the Overall Risk Score Includes](#what-the-overall-risk-score-includes).
Two things to know about where this section appears:
- It needs a **saved** property, so it isn't there while you're still entering a new one. Import or save the property first.
- **Land-only records** don't show the hazard section on the Building tab, since the building-focused view doesn't apply to them.
## Seismic Tier and 30-Year Probability {#seismic-tier-and-30-year-probability}
The Seismic Risk card carries two fields that the other five hazards don't have.
**30-Year Probability** is the underlying figure: the modeled chance of strong shaking at this location in the next 30 years. **Seismic Hazard Tier** groups that figure into four bands:
| Tier | 30-year probability |
|---|---|
| **Low** | under 3% |
| **Moderate** | 3 – 6% |
| **Elevated** | 6 – 26% |
| **High** | 26% and above |
**The badge and the tier are on different scales; this is not a bug.** The colored badge in the card header uses the same five-level vocabulary as the other five hazard types, so the four seismic tiers are mapped onto it: both **Elevated** and **High** tiers display a **High** badge, and **Moderate** displays a **Medium** badge. The tier row carries the finer-grained reading, so a property showing "Elevated" beside a "High" badge is behaving correctly; read the tier row for detail.
**A high tier is not a reason to walk away.** Much of Japan's Pacific coast, including most of Greater Tokyo, sits in the High band, and the platform says so on the card itself: *"High hazard — normal for much of Japan's Pacific coast. Mitigate through building-standard verification and earthquake insurance rather than treating this as disqualifying."* The practical response is to check the building's construction standard and to price earthquake insurance, not to exclude the location. A High seismic tier tells you what to verify next; it does not rank the property against alternatives, because nearly every alternative in the same region carries a similar figure.
## Location Shaking vs Building Era {#location-shaking-vs-building-era}
"Seismic" describes **two separate things** in Japanese real estate, and they are easy to conflate:
- **Location shaking hazard**: how strongly the *ground at this address* is expected to shake. This is what this page describes, and it comes from the national seismic hazard model.
- **Building 耐震 standard**: whether the *structure* was built to the current earthquake code. Buildings permitted before the 1981 revision (旧耐震, *kyū-taishin*) were designed to a weaker standard than those after it (新耐震, *shin-taishin*).
These pair; they are not two readings of the same thing. A 新耐震 building on high-shaking ground and a 旧耐震 building on low-shaking ground are genuinely different risks, and you need both facts to judge either. The hazard data on this page answers the first question only; the building's era and structural condition come from the property's own records and from due diligence.
## Two Different Shaking Thresholds {#two-different-shaking-thresholds}
The map legend and the property panel both report a 30-year probability, but they measure **different shaking thresholds**, so their numbers will not match for the same location:
- The **map's Earthquake layer** measures the probability of **震度6強** (JMA intensity 6-Upper) or stronger.
- The **property panel's 30-Year Probability** measures the probability of **震度6弱** (JMA intensity 6-Lower) or stronger.
6弱 is the lower bar of the two (any shaking that reaches 6強 has also passed 6弱), so the panel's figure is the larger number for any given site. Both are correct; they answer slightly different questions. If you're comparing the two, compare like with like: use the panel figure for the property's own reading, and the map layer for how that site compares with the surrounding area.
For scale: 震度6弱 is shaking that makes standing difficult, moves heavy furniture, and cracks walls in lower-standard buildings. 震度6強 makes it impossible to stand and can collapse buildings that don't meet current code.
## What the Overall Risk Score Includes {#what-the-overall-risk-score-includes}
The **Overall Risk** reading at the top of the hazard panel is computed from **five hazards (flood, tsunami, landslide, storm surge and internal flooding)**, weighted by severity. **Earthquake is not part of it.**
This is why a property can show a Low overall risk beside a High seismic reading, as the screenshot above does. Nothing is contradictory: the overall score is summarizing water and landslide exposure, where that property genuinely scores low, while the seismic reading is reported separately on its own card.
The reason for the separation is that seismic hazard barely discriminates between properties in the same region; folding a figure that is High across all of Greater Tokyo into a comparative score would flatten the differences you're actually trying to see. So read the two together: **the overall score for comparing sites, and the Seismic Risk card for the earthquake picture.** The seismic data is fully present and assessed; it simply isn't blended into that one number.
When the earthquake reading is Moderate or above, the panel states this directly beneath the overall score.
## Data Sources and Limitations {#data-sources-and-limitations}
All hazard data is official Japanese government data, from two different sources:
- **The five water and landslide layers** come from the **GSI Disaportal** (国土地理院 ハザードマップポータルサイト), served as map imagery.
- **Earthquake data** comes from **J-SHIS** (Japan Seismic Hazard Information Station), published by the **National Research Institute for Earth Science and Disaster Resilience (NIED)**. See [www.j-shis.bosai.go.jp](https://www.j-shis.bosai.go.jp/).
Attribution lines appear in the legend only while a layer from that source is active, which is why the source text changes as you toggle layers.
Because earthquake data arrives through a different pipeline than the other five, it behaves differently in two visible ways: it is the only layer with an availability state, and it is published at a **coarser resolution**: the overlay stops drawing at very high zoom levels, so zoom out if the layer disappears while the others stay visible.
Four limits are worth stating plainly:
- **Seismic probabilities are statistical estimates over a 30-year window, not predictions of individual events.** A 66.9% figure does not mean an earthquake is scheduled; it means the model puts that likelihood on the threshold being crossed at least once across 30 years.
- **Seismic data is modeled on a roughly 250 m mesh**, so it describes a neighborhood rather than a single building footprint. Two properties on the same block share a reading.
- **Hazard mapping describes the site, not the structure.** It cannot tell you how a specific building will perform; that depends on construction standard, age, ground conditions on the parcel, and maintenance.
- **None of this substitutes for the 重要事項説明** (statutory disclosure) a licensed agent must provide before purchase, or for professional inspection and survey. Use it to shortlist and to decide what to investigate; verify before you commit.

title: Running AI Analyses
url: https://www.tatemonoiq.com/en/docs/running-ai-analyses
locale: en
type: documentation
section: analysis
description: Run an AI-powered investment analysis on any property: set financing assumptions, choose an analysis type and output language, monitor progress, and understand how results are shared with your team.
---
Tatemono IQ's AI analysis evaluates a property the way an experienced investor would, looking at rental demand, returns, pricing and cash flow, and delivers a written assessment of what the figures show together with the questions it could not answer. This guide walks through running your first analysis and managing the results.
## What the Analysis Does
The AI evaluates rental demand, expected returns, pricing relative to the market, and cash flow projections, then sets out what the figures show, including a favorability rating drawn from a fixed scoring rubric rather than an opinion about the property. It then sets out what it could not determine: data the property record was missing, figures that depend on assumptions you did not supply, and questions to put to a licensed professional. It closes with a priority-ordered list of items to confirm with the broker before you decide. The analysis draws on the property's imported data plus supporting datasets like nearby points of interest and hazard assessments.
## Start from a Property
1. Open any property you want to analyze.
2. Click the **Analysis** button to open the analysis menu.
3. Select **AI Analysis**.
You'll land on the analysis setup page for that property.
## Review the Property Summary
The property summary section shows the key details that will feed the analysis: location, building details, and available supporting data such as points of interest and hazard assessments. Review it before running; the analysis is only as good as the data behind it. If something important is missing, fill it in on the property first.
## Set Financing Assumptions
Enter your loan conditions: interest rate, down payment percentage, loan term, repayment method, and related terms. These assumptions drive the cash flow and return calculations, so match them to the financing you can realistically obtain; a full-cash purchase and an 85% LTV loan tell very different stories about the same property.
## Choose an Analysis Type
Pick the analysis that matches your question:
| Analysis Type | Best for |
|---|---|
| **Comprehensive Investment Analysis** | The full picture: start here for most properties |
| **Rental Demand** | Will this unit find tenants? |
| **Price Analysis** | Is the asking price fair? |
| **ROI Analysis** | Focused return calculations |
| **Minpaku/Airbnb Analysis** | Short-term rental potential under minpaku rules (capped at 180 rental days per year) |
| **Ryokan / Hotel-License Analysis** | Year-round guest operation under a hotel/inn (ryokan) license: no day cap |
| **Land Development Analysis** | Land value and development options |
**Cash Flow Ranking** is an eighth type available only when analyzing a [property list](property-lists); it ranks every property in the list by projected cash flow.
## Minpaku or Ryokan?
Both analyses model short-stay guest accommodation, but they assume different licenses, and the difference changes everything about the numbers:
- **Minpaku Analysis** models operation under Japan's minpaku framework (住宅宿泊事業法): a notification-based registration with a hard cap of **180 rental days per year**. Lower barriers to entry, but the revenue model is built around half-year occupancy.
- **Ryokan Analysis** models operation under a **hotel/inn business license** (旅館業法): a full permit from the local health office with **no day cap, 365-day operation**. In exchange, it carries stricter requirements: zoning (not permitted in exclusive residential districts), facility and front-desk standards, fire-code obligations, and typically one-time conversion costs. The analysis models these compliance factors and the year-round revenue potential, and compares the result against minpaku and long-term rental scenarios, including break-even on the conversion investment.
Rule of thumb: if you plan to operate under a minpaku notification, choose Minpaku. If you're evaluating whether a full hotel license would justify its higher cost and requirements, choose Ryokan. Asking the Minpaku analysis to assume 365 days via Additional Context won't work; it is anchored to the 180-day legal cap by design.
## Output Language and Additional Context
- **Output language**: choose the language for the analysis results. Useful when sharing with partners, clients, or lenders who read a different language than you do.
- **Additional context**: optionally give the AI extra instructions: your investment criteria, a concern to dig into, or an aspect to emphasize. For example: *"I plan to renovate and re-rent at a premium; assess whether the location supports higher rents."*
## Run the Analysis
Click **Run Analysis**. The process typically takes about a minute. Stay on the page while it runs; navigating away interrupts the analysis.
When it completes, the analysis is **saved to your account automatically**. Nothing to remember, nothing to lose.
## Where Your Analyses Live
The **Analyses** page in the main navigation collects every saved analysis. From there you can view any analysis, compare results across properties, re-run with modified parameters, or export to PDF.
## Monitoring Running Analyses
When analyses are in progress, a running jobs section appears at the top of the Analyses page. Each job shows real-time progress through its stages: fetching data, building the prompt, generating the analysis, and saving results. You can cancel a running job or retry a failed one from here.
## My Analyses and Team Analyses
The scope toggle on the Analyses page switches between two views:
- **My Analyses**: only analyses you created, across all teams you belong to. Your work, in one place.
- **Team Analyses**: analyses within a team. If you belong to multiple teams, use the team dropdown to focus on one.
When you arrive at the Analyses page by clicking a property's analysis count, a banner shows which property you're filtering by; you'll see all accessible analyses for that property, both yours and your team's.
## How Sharing Works
Who sees what depends on the type of team the analysis lives in:
- **In a real estate company's team:** Agents, Staff, and Owners see all analyses. Investors see only their own.
- **In your personal team:** You control sharing: every member you invite (including other Investors) can view all analyses in that space.
Run an analysis in the space that matches your intent: keep private research in a team where only you work, or analyze in a shared space when the result is meant for others' eyes.
## Next Steps

section: analysis
description: Compare Japanese markets before you compare properties: an interactive map of demographic, transaction-price, and land-price signals for all 47 prefectures, with drill-down to individual municipalities.
---
Most property mistakes are market mistakes: the right building in a shrinking town is still the wrong investment. The Market Intelligence Map lets you compare markets across Japan, every prefecture and municipality colored by hard government data, so you can decide *where* to invest before deciding *what* to buy.
Open it from **Market Intelligence Map** in the main navigation.
## Why Start with the Market
Japan's regions are on very different demographic and price trajectories. A property's long-term rental demand depends on how many households its area will have over your holding period, and its price justification depends on what buyers actually paid nearby, not on asking prices. The map puts those signals side by side for the whole country, quantified and comparable.
## The Three Metrics
Use the metric selector to switch what the map colors show:
| Metric | Unit | What it tells you |
|---|---|---|
| **Household CAGR 2025–2050** | % p.a. | Projected household growth or decline: the demand tailwind (or headwind) over a long holding period |
| **Median Transaction Price / m²** | ¥/m² | What buyers actually paid, from reported real transactions: an anchor for judging asking prices |
| **Land Price Change YoY** | % YoY | Direction and speed of official land values: market momentum |
Land Price Change is a diverging metric: the color scale is anchored at zero, so gaining and declining areas are visually distinct at a glance.
## Reading the Map
The national view shows all 47 prefectures as a choropleth; darker means higher for the selected metric.
- **The legend** (bottom of the map) shows the active metric with its unit, plus minimum, median, and maximum value ticks so colors translate to numbers.
- **Grey areas** mean "No data": no published figures for that area, not a zero.
- **Data sources**: expand the toggle in the legend for the official attributions.
- **Map controls** let you zoom in and out and reset the view at any time.
Hover any region for a quick reading; click it to select.
## Drilling into Municipalities
Click a prefecture to drill into its municipalities: the same metrics, computed per city, town, and village. The breadcrumb (Japan › Prefecture) tracks where you are, and **Back to prefectures** returns to the national view.
When you select a region, the map keeps you oriented: the selection is highlighted and labeled on the map itself, centered in view, with surrounding regions dimmed.
## The Region Panel
Selecting a region opens a details panel docked beside the map (it never covers the legend). The panel shows all metrics for the region:
- The metric currently displayed on the map carries an **"On map"** badge.
- Each value comes with context: whether it sits **above, below, or about the prefecture median**, so a number like ¥36,000/m² immediately means something.
- Yen values are shown whole; percentage changes are sign-colored so declines read as declines.
- Where the underlying sample is thin (common in small rural municipalities) you'll see a **"Low sample · figures indicative"** badge: treat those numbers as directional, not precise.
- Missing figures show **"No data"** rather than a misleading zero.
## From Insight to Properties
Found a market you like? Click **"View properties in \{region\}"** in the panel to jump to your property list filtered to that area, connecting the market view directly to the properties you've imported there.
The reverse workflow works too: when a property's AI analysis mentions demographic or price context, the map is where you can see that context spatially and compare it against neighboring markets.
## Where the Data Comes From
Every layer is built from official Japanese government data:
- **Household projections**: National Institute of Population and Social Security Research (IPSS) prefectural household projections through 2050
- **Transaction prices**: MLIT buyer-reported real estate transaction records
- **Land prices**: MLIT official land price survey points
- **Administrative boundaries**: MLIT National Land Numerical Information (国土数値情報)
Full attributions are available under the **Data sources** toggle in the map legend.

Your account settings shape how Tatemono IQ presents data to you, starting with the currency every price is displayed in. This page covers the essentials in the user menu: preferences, feedback, and where to find help.
## The User Menu
Click your avatar in the top-right corner to open the user menu. From here you can access your profile, download the browser extension for importing properties, send feedback, and manage your settings.
## Currency Preferences
Property prices and investment metrics are shown in **US Dollars by default**. If you'd rather work in Japanese Yen or another supported currency, change it in the currency preferences section of your profile:
1. Open the user menu and go to your profile.
2. Find the **Currency Preferences** section.
3. Select your preferred display currency.
Every price and metric across the app follows your choice. Investors comparing against home-market returns often keep their local currency; those negotiating in Japan usually switch to yen to think in the same numbers as the seller.
## Sending Feedback
Found a bug? Want a feature? The feedback form sends your thoughts directly to the team building Tatemono IQ, and every submission is reviewed.
1. Open the user menu and click **Send Feedback**.
2. Choose the feedback type:
- **Bug**: something isn't working
- **Feature Request**: new functionality you'd like
- **Improvement**: enhance an existing feature
- **General**: anything else
3. Describe your feedback and submit. You'll see a confirmation once it's sent.
Your email is included so the team can follow up if needed.
## Writing Feedback That Gets Results
A minute of detail turns feedback into action:
- **For bugs**, include the steps to reproduce: what you clicked, what you expected, what happened instead.
- **For feature requests**, describe your use case; the problem you're trying to solve matters more than a specific solution.
- **For improvements**, name the page or feature and what slows you down today.

description: How access control works in Tatemono IQ: personal teams vs. agency teams, the four access levels, the team badge and Teams menu, switching teams, and what each role can see and do.
---
Everything in Tatemono IQ (every property, analysis, and list) lives inside a team. Teams are how the platform decides what you can see and what you can do. Understanding the two kinds of teams and the four access levels explains almost every "why can I (or can't I) see this?" question.
## Two Kinds of Teams
**Personal teams** are private workspaces. When you sign up for Tatemono IQ, a personal team is created for you automatically, named after you (for example, "Ken's Team"). Properties you import, analyses you run, and lists you build there are yours. You are the owner, so you have full control, and you can invite other people (always as investors) into it if you choose to share your research. Every investor is guaranteed a personal team; colleagues who joined the platform through an agency team invitation work in that team instead.
**Agency teams** are shared workspaces created by real estate companies. The team typically carries the company's branding, and its members work together with roles: agents and staff manage the property library, and invited investors get a view into it. If an agent invites you to their team, you keep your personal team; the two exist side by side, and you can belong to any number of teams.
## The Four Access Levels
Within a team, what you can do is determined by your role. There are three assignable roles (**Agent**, **Staff**, and **Investor**) plus the **Owner**, who is the person the team belongs to and holds every permission automatically.
Default capabilities in an agency team:
| Capability | Owner | Agent | Staff | Investor |
|---|---|---|---|---|
| View properties & brokers | ✓ | ✓ | ✓ | ✓ |
| Add & edit properties | ✓ | ✓ | ✓ | — |
| Delete properties | ✓ | ✓ | — | — |
| Invite team members | ✓ | ✓ | ✓ | — |
| Change roles & remove members | ✓ | ✓ | — | — |
| Invite investors & share properties | ✓ | ✓ | — | — |
| Team settings, permissions & billing | ✓ | — | — | — |
Two things to keep in mind:
- These are the **defaults**; a team owner can adjust what each role is allowed to do (see [Customizing Role Permissions](#customizing-role-permissions)), so capabilities can differ from team to team.
- In your own personal team you are the owner, so all of this applies to you automatically there.
## The Investor Role Is Permanent
The Investor role is a one-way door: once a user is an investor, their role cannot later be changed to Agent or Staff. That's why the app shows a confirmation warning whenever you assign it. The flip side is that every investor automatically receives their own personal team, so they always have a private workspace of their own regardless of which agency teams they join.
## Your Active Team
You are always working *in* one team at a time: your **active team**. The team badge in the upper-left corner of the screen shows which one:
- For an agency team, the badge shows the company's logo (or the team's initials if no logo is set).
- For your personal team, it shows the Tatemono IQ logo.
Click the badge to open the team information panel: the team's property, member, and saved-analyses counts, the team owner, and a shortcut to Team Settings.
## Switching Teams
Open the **Teams** menu in the top navigation to switch. All the teams you belong to are listed, with a checkmark on the active one; click any team to make it active. The same menu holds your team management entries (Team Settings, and for owners, Permissions and Beta Features) and shows a badge when you have pending team invitations.
Switching teams switches your whole working context:
- The **property list refilters** to the new team's properties; the active team is effectively a property filter that's always on.
- **Analyses and lists** follow the same scope.
- **Your permissions are re-evaluated**; you might be an owner in one team and an investor in another, and the app's buttons and menus adjust accordingly.
## Filtering by Team Without Switching
Inside the property filter panel there's an **Access Control** section with a Team dropdown. Use it when you want to narrow the property list by team temporarily without changing your active team, useful if you belong to several teams and are comparing inventories.
## What Investors See in a Team
Investors get a deliberately safer, read-oriented view of an agency team:
- **Published properties only.** Drafts an agent is still preparing don't appear for investors. (In your personal team, you always see your own properties at every stage.)
- **Addresses can be masked.** Agents may hide exact addresses, in which case investors see an area-level location on the map instead of a pin on the building. The agent can lift this per investor with the "Show full address to this investor" setting in Team Settings.
- **Investor analyses are private from each other.** In an agency team, an investor never sees another investor's analyses; agents, staff, and the owner see all of the team's work. In a personal team it's the reverse philosophy: everyone you invite can see all analyses in that space; you control sharing by controlling membership.
## Customizing Role Permissions
Team owners can tune what each role is allowed to do in their team: open **Teams → Permissions**, pick a role, and toggle individual permissions. The changes apply only to that team; the same person can have different capabilities in different teams.

description: The two ways to bring an investor into your team: email invitations from Team Settings and secure, email-locked share links generated from any property's Share command.
---
Getting an investor into Tatemono IQ takes one of two paths: invite them to your team directly, or share a specific property with them and let the property do the selling. Both end the same way, with the investor joining your team with the Investor role, but they start from very different moments in your relationship.
Inviting investors requires the invite-investor permission; by default that's team **Owners and Agents** (see [Teams & Roles](teams-and-roles)).
## Two Ways to Bring an Investor In
- **Team invitation**: you already know the person and their email. Invite them from Team Settings; they get access to your team's whole published library.
- **Property share link**: you want to show one specific property, perhaps to someone who has never used Tatemono IQ. The Share command creates a secure, email-locked link to that property; when the recipient registers through it, they join your team as an investor.
## Inviting by Email from Team Settings
1. Open **Teams → Team Settings**.
2. In the **Team Members** section, click **+ Invite Member**.
3. Enter the email address and choose the role: **Agent**, **Staff**, or **Investor**. (Assigning the Investor role requires the invite-investor permission, Owners and Agents by default. Staff can invite new agents and staff, but not investors.)
4. Click **Send Invitation**.
When you pick the Investor role, a confirmation dialog reminds you that the assignment is permanent: an investor can never later become an agent or staff member, and they'll receive their own personal team. This is expected; confirm and send.
The invitee receives an email with a join link. If they already use Tatemono IQ, they'll also see the invitation inside the app (a notification badge and a **Pending Invitations** entry in the Teams menu) where they can accept or decline. New users register through the link; new investors automatically get their own personal team alongside their membership in yours.
## Sharing a Property from the Property Menu
The **Share** command appears on the property menu for **published** properties (drafts can't be shared).
1. Open the property and choose **Share** (also available from the property card menu on the Properties page).
2. Enter the **recipient's email address**; the link will only work for that address.
3. Optionally add a **Personal Note** (up to 500 characters). The recipient sees it when they open the link.
4. Click **Generate Share Link**, then **Copy**, and send the link through email or any channel you like.
Three properties of the link worth knowing:
- **Email-locked.** The recipient must verify the exact email address you entered. A forwarded link is useless to anyone else.
- **Time-limited.** Links expire after 30 days.
- **Single-use for joining.** Once the recipient redeems it and joins your team, the link's job is done; from then on they sign in normally.
## What the Recipient Experiences
The recipient opens the link and is asked to verify their email address. Once verified, they see a clean, read-only property page: photos and floor plans, the key figures, broker information, your personal note, with a language selector and a PDF export button. No account is needed to view it.
From there, the path depends on who they are:
- **New to Tatemono IQ**: a short registration form (name and password). On completion they join your team as an Investor, get their own personal team, and land directly on the property inside the app.
- **Existing user**: they sign in, and joining your team happens automatically.
Either way they receive a welcome email confirming they've joined your team.
## What a Share Link Reveals and Hides
The shared page shows what a prospect needs: the address line, asking price, expected yield, building details, photos and floor plans, and broker contact information, localized to the viewer's language.
It deliberately withholds your internal material: notes, financial analysis, cost basis, cap rate, and NOI never appear, and neither do map coordinates or fine-grained address components. What you write in the Personal Note field is the only commentary the recipient sees.
## Managing Pending Invitations
Team Settings lists every outstanding invitation with its role and date. From there you can:
- **Resend** an invitation that got lost, available once per hour per invitation.
- **Cancel** an invitation to invalidate its link.
The Teams menu badge counts invitations awaiting *your* response across all your teams.
## Controlling Address Visibility
Sharing a property is separate from revealing its exact location. If a property's address is hidden, investors see an area-level location rather than the precise spot, both in the team workspace and on maps. When a particular investor relationship warrants it, grant an exception in Team Settings with **"Show full address to this investor"** next to their name. See [Teams & Roles](teams-and-roles) for the full visibility model.

title: September 2026: Property tax with the residential-land special, Japan's land rules stated precisely, and one click to walk to the station
url: https://www.tatemonoiq.com/en/updates/september-2026
locale: en
type: update
publishedAt: 2026-09-30
summary: Property-tax estimates now apply Japan's residential-land special (住宅用地特例), and the land-acquisition notices in your analysis describe who files, when, and that nothing needs government approval. Maisoku flyers carry seismic information and REINS advertising-consent records, rental analyses for single-occupancy units consider single seniors as a tenant segment with the risk priced and mitigated, and every property page gains a one-click walk to the nearest station.
---
April was about data, May about personalization, June about judgment, July about risk and location, August about precision. September was about the rules. A Japanese property investment is governed by a dense layer of tax law, land law and advertising practice, and a figure that looks precise is only useful if it follows those rules. So this month we taught the analysis how Japan actually taxes residential land, rewrote every land-acquisition notice against the statutes themselves, and brought the Maisoku flyer in line with the disclosure and advertising rules an agent works under. Here's what shipped.
## 1. Property tax that reflects the residential-land special
Residential land in Japan is almost never taxed at the headline rate. Under the **住宅用地特例 (residential-land special)**, the taxable base for **固定資産税 (fixed-asset tax)** falls to one-sixth of the assessed value for the first 200 m² per dwelling and one-third beyond that, and the base for **都市計画税 (city planning tax)** falls to one-third and two-thirds respectively. Analyses previously applied the flat rates, which overstated the holding cost of almost any residential property.
When you don't supply a tax figure, the analysis now **estimates both taxes with the special applied** to the residential land, and the same calculation feeds the cash-flow figures, the tables and the narrative, so they agree. The Property Tax box on the analysis form now starts empty and marked **Auto**, so the estimate runs by default. If you have the actual figure from the tax notice, type it in and your figure is used instead.
The **minpaku analysis** now covers the other side of the same rule. Converting residential floor area to short-stay lodging can reduce or remove the special on the land, and the analysis flags that property-tax risk, applying the mixed-use thresholds where they're relevant: a residential share of at least half keeps the special on all of the land, a share between a quarter and a half keeps it on half, and below a quarter it is lost.
*Source: 地方税法 (Local Tax Act) residential-land special provisions for 固定資産税 and 都市計画税*
## 2. Japan's land-acquisition rules, stated precisely
Three different regimes can require a filing when land changes hands in Japan, and none of them is a government approval. Every notice in the analysis has been rewritten against the statutes:
- **国土法 (National Land Use Planning Act).** The filing is made **after** the contract, within two weeks, and it applies to **every buyer regardless of nationality**. The area thresholds are now applied exactly as written: **2,000 m² or more** in an urbanization area (市街化区域), **5,000 m² or more** elsewhere in a city planning area, and **10,000 m² or more** outside one. A parcel of exactly 2,000 m² is now correctly flagged.
- **外為法 (Foreign Exchange and Foreign Trade Act).** Buyers who are **non-residents** of Japan file a post-acquisition report. This depends on residency, not nationality, and the analysis now says so.
- **重要土地等調査法 (the law on land near important facilities and border islands).** In specially designated zones, buyer and seller give notice **before** the contract. It is a notification, not an approval: the filing does not screen or block the purchase.
This matters most on exactly the properties where a buyer from outside Japan is already most cautious. A notice that implies the state can refuse a sale inflates a risk that does not exist, and the analysis now describes each obligation as it actually is.
*Source: 国土利用計画法 Art. 23; 重要土地等調査法 and the Cabinet Office FAQ; 外為法*
## 3. Single seniors, considered as a tenant segment
Single-person households are 38% of Japanese households (2020 Census) and growing, and single seniors are a substantial renter segment for exactly the older studio and 1K stock many investors analyze. Rental analyses for **single-occupancy units** now consider them as a tenant segment: what they look for (ground-floor or elevator access, nearby clinics, guarantor-company acceptance) and what they tend to offer a landlord in return, which is long tenancies and very low turnover.
The analysis also prices the uncommon tail scenario that makes some landlords hesitate, a **孤立死 (solitary death)** that goes undiscovered for a period, and sets out how professionals mitigate it: monitoring services (見守り), a solitary-death insurance rider on the landlord's fire policy, the government's model contract clauses for handling belongings (残置物モデル契約条項), the **終身建物賃貸借 (lifetime building lease)**, and certified rent-guarantee and housing-support providers. It also states plainly that, under MLIT's guideline, a natural death discovered promptly normally creates no disclosure obligation.
The framing is deliberate. The risk is priced and mitigated, never avoided: the analysis will not recommend declining tenants on the basis of age. Family-sized units are unaffected and do not grow this section.
*Source: 2020 Census; MLIT guideline on disclosure of deaths in real estate transactions (2021); MLIT and Ministry of Justice model contract clauses*
## 4. Maisoku flyers: seismic information and advertising consent
The Maisoku (マイソク) flyer now answers both halves of the question a buyer asks about earthquakes. The hazard band shows **earthquake as the sixth hazard type** alongside flood, tsunami, storm surge, landslide and inland flooding. Where the earthquake hazard has not yet been assessed for a property, the flyer says **Not yet assessed** rather than printing "None", because no location in Japan has zero seismic probability. The building block gains an **耐震基準 (seismic standard)** row: a value recorded for the property prints as recorded, and a value derived from the year built is marked "(inferred from year built)" so it is never read as certified compliance. The flyer states the era as fact and leaves the risk discussion to the analysis, in line with Japanese advertising practice.
For agents working with listings from another brokerage, Tatemono IQ now records the listing's **REINS 広告転載区分 (advertising reprint permission)**, read from the REINS sheet at import where it is present, and lets you attach a **consent record from the listing broker (元付)**: the date, the media the consent covers, a note and a supporting file. The export advisory about another firm's listing now appears only when it applies, and stays out of the way when permission is on record.
Two flyer fixes round this out: the location map is now centred on the property's own area, and the approximate-location label renders correctly in Japanese.
*Source: J-SHIS seismic hazard model, NIED; REINS 利用ガイドライン (usage guidelines)*
## 5. One click from the property page to the walk to the station
Every property page now has a **Walk to Station** button alongside Analysis, Maisoku PDF Export and Edit. One click opens the walking route to the nearest major station, with the distance, the estimated walking time, the station's name and its lines, and the **Virtual Street Tour** ready to start. It is the same experience the map panel offers, now reachable directly from the property itself.
The neighbourhood data behind it got more accurate too:
- **Walking times in dense areas are routed.** Properties with many stations nearby, typically in central city districts, were falling back to straight-line distances. New and refreshed lookups now measure the actual walking route.
- **Nearby places are classified more accurately.** Shinto shrines are recognized as shrines rather than churches, and a courier company's service centres are no longer listed as post offices.
- **Cemeteries are no longer read as an amenity.** Unnamed cemetery fragments no longer inflate the count of nearby places, and cemeteries no longer count toward a location's religious-facility rating.
- **Addresses are matched more precisely.** Imported addresses are now classified as 住居表示 (residence-indication numbering) or 地番 (registry lot numbering) using the Digital Agency's Address Base Registry, so lot-numbered addresses are located in the right form.
*Source: Digital Agency Address Base Registry (アドレス・ベース・レジストリ)*
## 6. Reports that read correctly in every format and language
- **Every Japanese character, in every PDF.** The analysis PDF now renders Japanese-specific characters in full, whatever the export language, so cost-panel labels and terms such as 旧耐震基準 (old seismic standard) print in full.
- **The Investment Assessment is in the PDF.** The assessment label and its rationale now appear in the exported calculations panel, including the Indeterminate state, explained rather than presented as a negative verdict.
- **Japanese exports read as Japanese.** The yield methodology card in a Japanese PDF carries the Japanese formula, and the acquisition-cost total reads as a single, correctly labelled percentage of the asking price.
- **Your language, throughout.** The assessment rating in Japanese, Korean and Chinese analyses now appears in that language instead of English. Missing information is named in plain words rather than as internal field names, and structure codes such as RC are spelled out (Reinforced Concrete) on first use in list analyses.
- **Shared links look like the app.** Analyses you share now render their tables, scorecard and investor questions properly in the browser, in every language.
## 7. When a trial ends, you can still buy what you need
When a free trial ended without a subscription, an account used to sit in a paused state where you could neither import nor analyze, and buying more required subscribing again. That state is gone. An account without a subscription is now **Pay as you go**: buy a property or analysis bundle whenever you need one, and your remaining balance is shown on Usage & Quota. Subscribing again is the ordinary plan checkout, whenever you're ready.
The bundle checkout itself is more forgiving too: a stray click outside the payment window no longer closes it and discards what you've typed.
## Also improved in September
- **Calculators start from the right numbers.** Opened from a property, the Cash Flow and Pro Forma calculators now prefill annual rent from the stored monthly rent and vacancy from the stored occupancy rate in the correct units.
- **Exports carry no internal identifiers.** The list-analysis PDF names the list and the number of properties analyzed, with no internal record numbers.
- **One place card at a time on the map.** Clicking a second nearby-place marker now replaces the open card instead of stacking another on top.
- **Plan descriptions match the trial.** Plan descriptions on the pricing page no longer quote a trial length that contradicts the trial shown on the card, in any of the five languages.
- **Seismic data is credited correctly.** Analyses that use earthquake data now credit J-SHIS and NIED as its source.

title: August 2026: Verified figures, statutory acquisition costs, and analyses fully in your language
url: https://www.tatemonoiq.com/en/updates/august-2026
locale: en
type: update
publishedAt: 2026-08-31
summary: Every analysis now passes through a validation layer before it reaches you: currency conversions are re-derived from the authoritative rate, yields are reconciled across the narrative, the tables and the PDF, and acquisition costs are computed from Japan's statutory schedules for your property's actual price. Analyses render completely in your chosen language, a new section sets out what the analysis could not determine and which licensed professional to ask, and condominiums in Japan's major developer brand series are recognized by name.
---
April was about data, May about personalization, June about judgment, July about risk and location. August was about precision. As the analysis has taken on more of the work an investor would otherwise do by hand, the standard it has to meet has risen with it: every figure needs to be verifiable, reproducible, and consistent wherever it appears. So this month went into the machinery behind the report, a verification layer that sits between the calculations and the page, statutory computation for the costs that depend on Japanese law, and a single authoritative record behind every analysis. Here's what shipped.
## 1. A verification layer between the calculations and your report
Tatemono IQ computes the figures that matter and hands them to the AI to write about. August added a layer that verifies the finished report against those calculations before it is saved.
**Currency conversions are re-derived.** Every ¥X (approximately $Y) pair in an analysis is parsed back out of the finished text and recomputed from the same authoritative exchange rate the analysis was generated with. Anything outside a rounding tolerance is corrected before the analysis is persisted, so your report, your PDF export and any link you share all carry the same verified figures.
**Yields are reconciled everywhere they appear.** Reconciliation now covers the narrative prose, the summary tables and the PDF together, so the yield quoted in a sentence and the yield in the table are the same number, and the narrative is checked against the analysis's own calculations block.
**Unknowns are reported as unknown.** Where a figure genuinely cannot be derived from the property record, the analysis says so instead of presenting a placeholder as a result. An expense ratio is reported only when gross rent is known, and an unknown net yield is carried through as unknown rather than being scored.
**Price-anomaly checks run on every path.** The checks that catch data-entry errors in price now run on every route that generates or regenerates an analysis, and are correctly scoped for sectional-ownership units (区分), where a building's total unit count (総戸数) describes the building rather than the holding being analyzed.
## 2. Acquisition costs, computed from Japan's statutory tables
Acquisition costs are now computed on the server from the statutory schedules, for **your property's actual price**: the stamp duty (印紙税) bracket that applies at that price, and the brokerage commission under 宅建業法, including the ¥330,000 tax-inclusive ceiling for properties under ¥8M introduced by the 2024 reform.
The panel you see is populated from that same statutory computation, so the figures in front of you are the correct ones for the property before you touch anything. If you do want to model different assumptions, the system now tracks precisely which fields you edited: your overrides apply, and every field you leave alone stays on the statutory basis.
*Source: Japan statutory acquisition-cost schedules (印紙税 price brackets, 宅建業法 brokerage commission rules incl. the July 2024 low-price reform)*
## 3. One authoritative property record behind every analysis
An analysis can be started several ways: from the property page, from a list, in a batch. All of them now assemble their data from a single authoritative source, so **every analysis reads the complete property record** (building structure, storeys, unit count, floor area, zoning and the rest) regardless of how it was triggered. The same property gives you the same analysis, and a build-time guard now proves that every field the report can display has a producer behind it, so the report and the data stay in step as both grow.
Converging on one record also brought the **demolition-cost estimate** into service: it now renders for the properties it was designed for, land-only listings and detached houses past the age threshold.
The **Property Scorecard** gained the same reproducibility. Its Financial Returns rating is now scored against explicit numeric yield bands rather than a qualitative judgment, so identical figures produce an identical star rating every time you generate an analysis, in every language.
## 4. A new section: What This Analysis Could Not Determine
Every analysis now closes with a section titled **What This Analysis Could Not Determine**, covering three things:
- **Data that was not available**, named as specific fields rather than a general note about limited data.
- **Figures that depend on an assumption you did not supply**, with the assumption restated next to the figure.
- **Questions for a licensed professional**, each matched to the right profession: a certified real estate appraiser (不動産鑑定士) for valuation, a certified tax accountant (税理士) for tax treatment, a judicial scrivener (司法書士) for title and registration, a licensed real estate transaction agent (宅地建物取引士) for transaction disclosures, and an administrative scrivener (行政書士) for permits and licensing.
This section replaces the analysis's closing recommendation, and the change is deliberate. Tatemono IQ is a research and analysis tool, not a licensed investment adviser and not a licensed appraiser (不動産鑑定士). The figures, the risk profile, the market context and the side-by-side comparison of strategies are all still there, and they are sharper than they have ever been. What sits at the end of the report now is the set of open questions to take to the right professional, which is a more useful place to finish than a verdict. The guided tour was updated to match.
## 5. Major developer brand series, recognized by name
For condominiums, the developer behind the building is a genuine quality signal, and in Japan it is usually legible from the building's own name. The analysis now matches a property against a curated list of the major developers' branded series: Mitsui Fudosan's Park Homes (パークホームズ), Park Court and Park Tower; Mitsubishi Estate's The Parkhouse (ザ・パークハウス); Sumitomo Realty's City House and City Tower (シティタワー); Nomura Real Estate's Proud (プラウド); Tokyu Fudosan's Branz (ブランズ); Daiwa House's Premist (プレミスト); and Sekisui House's Grande Maison (グランドメゾン).
When a match is found, whether in the property name, the developer field, the management company or the constructor, the analysis and the synopsis name the series and treat it as a positive factor for construction quality and professional management. Two deliberate constraints keep it trustworthy: matching is exact against a curated list rather than a fuzzy guess, so an unrelated company that happens to share a word is never mistaken for a brand series; and where there is no match, the analysis is explicitly instructed **not to speculate** about the developer's or management company's reputation. Silence is the honest answer there, not an invented one.

## 6. Analyses that render completely in your language
Localization now reaches the structural furniture of the report, not just the prose. The Financial Summary table's column headers and row labels, the entire Property Scorecard table, and the Property Assessment block all render in the language you asked for, in the app and in the PDF export, across Japanese, Korean, Simplified Chinese and Traditional Chinese. Traditional Chinese output is additionally checked for script purity on save, so Simplified characters cannot slip into a zh-TW analysis.
**Follow-up questions were rebuilt on structured output.** Rather than being parsed out of free-form text, the questions and their supporting metadata now come back as structured data, which makes extraction reliable in every language and makes the feature straightforward to extend. Questions are scoped to one topic each where that reads more naturally to a Japanese counterparty, and existing non-English analyses were reprocessed so they carry their follow-up questions too.
## 7. Start on your phone, continue at your desk
The core workflow, importing a listing with the browser extension or uploading a Maisoku (マイソク) PDF, is built for the desktop. Signing up on a phone now bridges to that instead of stopping at it.
New accounts opened on a phone see a one-time screen explaining what the desktop experience covers and what you can explore right now, with a single tap to **email yourself a link to continue on desktop**. You can also dismiss it and carry on browsing the demo analyses on your phone. It appears once per account, in all five languages, and never on desktop.
## Also improved in August
- **More control over analyses in flight.** A Cancel option is available for any analysis that has not yet finished, not only long-running batch jobs. Quota is returned automatically when a job does not complete, and a submission that your subscription does not currently permit returns a clear explanation of why.
- **Aki reads your whole result set.** Ask about your search results at any page size and Aki answers from all of them, with counts, cities, and price and yield ranges drawn from your actual visible set. Exchange-rate figures stay accurate throughout a long conversation and in every display currency.
- **Fresher, cleaner underlying data.** Production station ridership is now on the current MLIT survey year, with figures for 262 more stations. The open-data amenity layer is filtered to Japan at the point of extraction, removing roughly 195,000 points that fell inside the extraction bounds but outside the country. POI refreshes now verify index parity as part of the run.
- **Maisoku export reflects your own relationship to the listing.** The transaction mode (取引態様) printed on an exported flyer describes the exporting team's own position, and the export flow notes that redistributing another firm's listing requires that firm's permission. On the property form, transaction mode is validated against property status before you save, and the analysis is told when a record is internally inconsistent.
- **Presentation polish across the report:** approximation symbols render as intended, prefectures appear as their names alone, and the disclaimer on list analyses is scoped to the data those analyses actually use.

title: July 2026: Earthquake risk built in, a one-step trial, and the market map goes GA
url: https://www.tatemonoiq.com/en/updates/july-2026
locale: en
type: update
publishedAt: 2026-07-31
summary: Every property now carries an official earthquake-hazard rating from J-SHIS: on the property page, on the map, and inside the AI analysis, paired with the building's seismic standard. The Market Intelligence map left beta with municipality-level drill-down, starting a free trial no longer requires a checkout step, and a new Ryokan analysis type models full 365-day hotel operation.
---
April was about data, May about personalization, June about judgment. July was about the two questions every investor asks before anything else: *how risky is this, really?* and *how fast can I see for myself?* We built earthquake risk into every property using Japan's official seismic hazard model, took the Market Intelligence map out of beta with drill-down to the municipality, and rebuilt the first five minutes of the product: sign up, and a fully analyzed property is already waiting for you. Here's what shipped.
## 1. Earthquake risk, from Japan's official seismic hazard model
Every property's hazard assessment now includes **earthquake**, the sixth hazard type, alongside flood, tsunami, and the rest. We draw it from **J-SHIS**, the national seismic hazard model published by NIED, Japan's disaster-science research institute: for each property you see a clear hazard tier and the headline figure behind it: the probability of strong shaking (JMA intensity 6-lower or higher) within the next 30 years.
We were careful with the framing, because raw earthquake numbers mislead. Much of urban Japan, including most Pacific-coast metros, carries a high baseline probability, and that's normal; what separates a sound purchase from a risky one is not the hazard figure alone but how the building answers it. So the rating is presented the way a professional would present it: hazard, then mitigation, and the **AI analysis now reasons about the two together**, pairing the local probability with the building's seismic-standard era (新耐震 / 旧耐震) to tell you what the number actually means for *this* building. There's also a new **seismic hazard overlay** on the property map, so you can see how shaking probability varies across an area at a glance.
*Source: J-SHIS seismic hazard model, NIED (National Research Institute for Earth Science and Disaster Resilience)*
## 2. The Market Intelligence map leaves beta and drills down to the municipality
The prefecture market map introduced in May is now **generally available for every user**, and it goes a level deeper: click a prefecture and it opens into a **municipality-level choropleth**, with a detail drawer for the city or ward you select. Properties are now matched to municipalities precisely (using official JIS municipality codes rather than address-text guessing), so filtering from the map to your properties lands on exactly the right ones.
The same municipal data now feeds the AI: property analyses cite **market context for the property's own municipality** (transaction activity and price signals for the actual city or ward) instead of stopping at the prefecture.
*Source: MLIT transaction and land-price data + IPSS demographic projections, keyed to official JIS municipality codes*
## 3. Sign up, and a property is already waiting for you
Starting a free trial used to walk you through a checkout page. That step is gone: **choose your plan and you're in**, no checkout, no card. And the first thing you see is no longer an empty workspace: every new account comes with a **demo property and a complete showcase analysis**, so you can explore what a full Tatemono IQ analysis looks like before you've imported anything of your own. A new **getting-started checklist** then walks you through the steps that matter (importing your first property, running your first analysis), and property setup got lighter touches too, like auto-generated property codes.
## 4. A new analysis type: Ryokan (旅館業法)
Some properties aren't 180-day minpaku candidates; they're candidates for a **full hotel/inn license (旅館業法)** and year-round operation. There's now a dedicated **Ryokan analysis type** for exactly that. It models the 365-day operating economics (room rates × occupancy, staffing and service costs), the licensing path (a permit from the public-health office, not a minpaku notification), zoning eligibility, and the one-time conversion investment a facility-standards and fire-code upgrade typically requires, then puts the result **side by side against minpaku and long-term rental** so you can see which strategy the property actually supports.
## 5. Maisoku export, redesigned
The Maisoku (マイソク) PDF export got a **professionally redesigned default template**: fields prioritized the way standard Japanese property sheets order them, a compact location map up top, and broker/team logos rendered at their correct proportions. Address privacy is now enforced end to end: when a property's exact address is restricted, every part of the export respects it: the map shows an area boundary instead of a pin, and the printed address and AI-written synopsis stay at area level too.
## 6. Import from Hatomark Site, and a more forgiving extension
The browser extension now supports **hatomarksite.com (ハトマークサイト)**, the listing portal of Japan's national real-estate association network, bringing one-click import to another major listing source. Imports also got more forgiving: a listing with an odd or incomplete field now **saves as a draft** for you to finish in the app instead of failing outright, and floor counts are read correctly on buildings with basement levels. The Chrome Web Store listing was polished too, with proper screenshots and localized descriptions in all five languages.
## 7. Help, right where you need it
The product documentation now lives **inside the app**, so there is no more switching to the website to look something up. We added new guides for **Teams & Roles** and **Inviting Investors & Sharing Properties**, and Aki, your AI assistant, learned the documentation too: ask which listing sites the extension supports, or where to find a guide, and Aki answers and points you to the right page.
## Also improved in July
- **The price you see is the price you're billed.** Signup and checkout now carry your language and displayed currency end to end, including on resumed subscriptions, which previously could re-bill in a stale currency.
- **Smoother sign-in:** email addresses are no longer case-sensitive at login, sign-in errors are actually shown instead of failing silently, and email-verification screens now report exactly what happened.
- **AI analysis polish:** the narrative and the numbers tables can no longer disagree on figures like net yield, internal codes and model self-talk no longer leak into the output, and cost-approach (積算) valuations are computed correctly for sectional-ownership units.
- **The AI engine was upgraded**: property analyses and Aki now run on a newer generation of Google's Gemini models, with faster responses and sharper reasoning.
- The property form no longer loses unsaved input when you switch languages.

title: June 2026: Demand-driver intelligence, an analysis that reasons like a local, and one-click install
url: https://www.tatemonoiq.com/en/updates/june-2026
locale: en
type: update
publishedAt: 2026-06-30
summary: The AI analysis now reads the institutions around a property as rental-demand signals (universities tagged with their student enrollment, hospitals with their bed count, research clusters as a category of their own), all on a rebuilt open-data amenity layer. We also hardened the Investor Fit Score around your strategy, made maps honest about approximate addresses, and put the browser extension on the Chrome Web Store.
---
In April we folded Japan's authoritative data into the platform; in May we put it to work with a personalized Investor Fit Score and a market map. June was about judgment: we taught the analysis to read the neighborhood around a property as rental demand (which universities, hospitals, and research clusters actually shape who would live there), rebuilt that amenity layer on open data so the picture is complete and accurate, sharpened how the analysis reasons about Japanese real estate, and removed friction with honest maps and a one-click extension install. Here's what shipped.
## 1. The neighborhood, read as demand, not just dots on a map
Knowing what sits near a property is table stakes; what matters to an investor is *who that draws as tenants*. In June we rebuilt the nearby-amenities layer on open data (**Overture Maps, OpenStreetMap, and MLIT**) and, more importantly, taught the analysis to read the institutions around a property as **demand drivers**. Universities and colleges now carry their **student enrollment** (official MEXT figures), large hospitals carry their **bed count** (MHLW data), and research institutes and medical-R&D campuses are surfaced as their own category. So instead of a flat "university nearby," the analysis reasons the way a local would: a 20,000-student campus within walking distance means durable demand for compact 1K/1DK units with a sharp March–April turnover; a 600-bed hospital anchors a stable, long-tenancy cohort of medical staff; a research park points to higher-income, less price-sensitive professionals. Every property analysis now includes this demand-driver read, with campus-appropriate distance bands: a university 2 km away is still "close" in a way a convenience store 2 km away is not.
Rebuilding on open data paid off in coverage and accuracy too. The amenity picture is now complete and uncapped (we removed the old "20+" limit, so counts are exact), shrine coverage jumped more than tenfold by drawing on OpenStreetMap, and transit comes from MLIT's national rail and bus datasets.
*Source: Overture Maps + OpenStreetMap + MLIT, enriched with MEXT university enrollment and MHLW hospital data*
## 2. An AI analysis that reasons like a Japanese professional
The analysis got materially smarter about how property is actually evaluated in Japan. It now applies the right **yield basis** (gross vs. net / 表面・実質), checks **bank-financing feasibility** the way a lender would (積算評価 collateral valuation), flags **rebuildability** constraints (再建築不可 / 接道義務 road-frontage rules), applies the correct **brokerage-commission** rules by transaction type, and frames natural-disaster risk in balanced terms rather than alarmist ones. We also corrected the underlying facts the analysis cites: light-gauge-steel (軽量鉄骨) depreciation periods of 19 / 27 / 34 years by steel thickness, the ¥330,000 tax-inclusive commission cap for sub-¥8M properties under the July 2024 reform, and the 2,000㎡ land-notification threshold. We also added a name-fidelity safeguard so the analysis names the institution that's actually next door, not a more-famous one nearby.
*Source: Japan real-estate practice standards + on-platform analysis methodology*
## 3. The Investor Fit Score, hardened around your strategy
May introduced the Investor Fit Score; June made it sharper and strategy-aware. Returns are now compared on a like-for-like yield basis with the yield type named explicitly, and scoring understands whether you're investing for **income or appreciation**, so an appreciation-focused profile is judged on growth potential ("Solid appreciation potential for this location tier"), not against a gross-yield target it was never meant to hit. Location matching now considers **city and ward**, not just prefecture; risk alignment factors in the building's **seismic-standard era**; and we closed a gap in the demographic-fit scoring.
## 4. Honest maps, and addresses that land in the right place
Not every listing has a precise street address, and the map now says so honestly. Properties with an area-level or hidden address are drawn as the actual **neighborhood (chome) boundary** instead of a single, misleading pin, and they're flagged with an **"≈" marker** on the list and cluster maps so you can tell them apart from exact addresses at a glance; when no chome matches, the map falls back to the ward boundary. On the input side, property forms now include **address autocomplete** that captures the canonical coordinates at the moment you pick a suggestion, so an address is no longer re-geocoded from free text into the wrong ward, and English-language users now see a clean **English/romaji** rendering of each address (e.g. "3 Chome-16-9 Torikai, Chuo Ward, Fukuoka") while the Japanese address stays the source of truth.
*Source: Government boundary data + Google Places autocomplete*
## 5. Install in one click: extension on the Chrome Web Store
The Tatemono IQ browser extension, the fastest way to pull a listing into the platform, is now published on the **Chrome Web Store**. Install it in one click with automatic updates; no more downloading a ZIP or using "load unpacked." The in-app download page, the Import Properties guided tour, and the documentation all walk you through the new flow.
## 6. Two new market reports
We published two more live market reports this month. The newest, the **Japan Prefecture Demographic Demand Scorecard**, ranks all 47 prefectures by projected household growth through 2040 for the cohorts investors care about most (single adults aged 25–39 and elderly single-person households) using official IPSS 2024 projections. Earlier in the month we added **Tokyo vs. Regional Cities: Price Comparison**, which sets Tokyo's prices against major regional metros. They join our first report, *Japan Residential Property Prices 2020–2025*, on the [market reports](/en/market-reports) page.
*Source: IPSS 2024 prefectural household projections + MLIT transaction data*
## Also improved in June
- The **Market Intelligence map** now renders with Leaflet for faster load times.
- Refreshed **in-app guided tours**: the AI Assistant (Aki) tour now matches the current side panel, the Import tour covers the Maisoku (マイソク) PDF path, and there's a new tour for Lists.
- **Clearer property labels**: floor area is now labeled by building type: 専有面積 (Exclusive Area) for condominium units, 延床面積 (Total Floor Area) for other buildings.
- Stability and accuracy fixes across the board: AI analysis no longer crashes on unusual commercial listings, Maisoku PDF analysis was restored after Google retired an older vision model, and several map and geocoding errors were resolved, including a false "approximate address" transit warning that could appear on properties with an exact, confirmed address.

title: May 2026: Investor Fit Score, market maps, and commercial signals
url: https://www.tatemonoiq.com/en/updates/may-2026
locale: en
type: update
publishedAt: 2026-05-31
summary: We retired the one-size-fits-all A–F grade for a personalized Investor Fit Score, added a prefecture market map, brought in commercial cap-rate signals and government land-appraisal data, and put station ridership on the map.
---
We spent April folding more of Japan's authoritative data into the platform. In May we put that data to work for you: a score built around *your* criteria instead of a generic grade, a new market map, commercial cap-rate signals, and government land-appraisal data. The scale behind it is substantial: **2,484,879** property transaction records, **408,507** official land-appraisal points, and **57,600** household projections spanning all 47 prefectures through 2040. Here's what shipped.
## 1. A score built around you, not a generic grade
We've retired the AI Assessment Grade, the A–F mark that used to appear on every property. It's gone from everywhere a property shows up: listings, detail pages, analyses, and exports.
The problem with one grade for everyone is that it judges every property against the same fixed checklist, and that checklist doesn't match how differently investors actually buy. A property marked "D" by a generic standard can be exactly the right building for an investor who buys for the long term and isn't afraid of a place that needs work. The old grade answered "is this property good?" when the question that matters is "is this property right for *me*?"
In its place: the **Investor Fit Score**, a score calculated against the criteria you set yourself: location, property type, budget, return targets, how much risk you're comfortable with, and how long you plan to hold. A property only shows a Fit Score once you've set up your investor profile; without that, a score would just be a number that doesn't mean anything. You can build your profile now from your account settings (pre-release beta).
## 2. See a whole prefecture at a glance
There's a new **market map**: a color-shaded prefecture view you can switch between demographic and price layers, so you can see at a glance where population and prices are rising or falling before you zero in on a single building.
*Source: IPSS demographic projections + government land-price data (pre-release beta)*
## 3. Commercial properties get cap-rate and yield signals
For commercial and office buildings, analyses now include **market cap-rate and NOI yield signals**, so you can see how a property's expected return compares with appraised market benchmarks instead of guessing.
*Source: MLIT land appraisal reports (鑑定評価書)*
## 4. Government land-appraisal data, built in
We brought Japan's official **land-appraisal reports (鑑定評価書)** into the platform. This is the same data professional appraisers rely on, and it now feeds both the market map's price layer and the commercial signals above.
*Source: MLIT (Ministry of Land, Infrastructure, Transport and Tourism) appraisal data*
## 5. Station ridership, now on the map
In April we started scoring connectivity; in May you can **see it**. Click a station on the property map and you'll get its daily ridership, and ridership now appears in the Transit section too. We also switched the map's station markers over to Japan's official rail database, so the stations shown are more accurate and complete.
*Source: MLIT rail station database + transit ridership data*
## 6. Smarter Maisoku (マイソク) import
Importing a property from a Maisoku PDF now captures far more detail (16 additional fields across the header, equipment, broker, station, and address) and it now reads **commercial and office** listings, not just residential. Less re-typing, fewer blanks to fill in by hand.
## Also improved in May
- **Aki**, your AI assistant, now opens the investor-profile chat properly and reliably saves what you tell it.
- A new in-app notification lets you know the moment a property's AI summary has been refreshed.
- Behind the scenes, we tightened how the AI analysis cites its numbers, so figures trace back to real data more consistently.

publishedAt: 2026-04-30
summary: Six major releases since launching this site, on top of 70+ improvements earlier in the month, all part of folding more of Japan's authoritative data into one AI-powered analysis layer.
---
We launched this site to coincide with the [Japan Real Estate Summit: Spring 2026 Session](https://nippontradings.com/events/japan-real-estate-summit-spring-2026-session/), a premier gathering for the international community buying, owning, and investing in Japanese property. Since then, we've kept the momentum going, shipping 6 major releases on top of the 70+ improvements we introduced earlier in the month. The thread running through them: Tatemono IQ keeps absorbing authoritative Japan-specific data sources (government hazard maps, IPSS demographic projections, transit ridership, municipal tax data) and folding them into a single AI-powered analysis layer. Generic listings tools and yield calculators don't have this. Here's what that looked like in April.
## 1. Location risk, visible at a glance
Hazard exposure used to be something an investor checked separately, on a different site, after they were already interested in a property. We pulled it forward: every property now shows flood, landslide, and tsunami risk directly on the map, sourced from the same government data the disaster planners use.
*Source: GSI (Geospatial Information Authority of Japan) hazard maps*
## 2. Demographic shifts, prefecture by prefecture
Demand is downstream of demographics, and demographics in Japan are changing faster than national headlines suggest. Property analyses now incorporate IPSS 2024 prefectural household projections and cohort-level breakdowns, so the demand picture for a property reflects where its market is actually heading, not where it was a decade ago.
*Source: IPSS (National Institute of Population and Social Security Research) 2024 projections*
## 3. Connectivity, scored not assumed
"Near a station" means very different things in Tokyo versus a regional city. Stations now carry ridership statistics and a tier classification (major hub, express, or local) so connectivity becomes a number an investor can compare across properties, not an adjective.
*Source: Transit operator ridership data, classified by Tatemono IQ*
## 4. Yield and expenses, fully shown
Yield numbers are easy to quote and easy to fudge. We show the full calculation, every input and every assumption, and we now include property tax in operating expenses by default. Investors who care about pro-forma accuracy can finally see what the model is actually doing.
*Source: Municipal property tax data + on-platform yield methodology*
## 5. Analyses an investor would actually request
The AI analysis layer learned a lot in April. Each analysis type now carries a plain-language description so investors know what they're getting, Japanese terminology was refined to match how local professionals actually phrase things, and the overall framing shifted toward an investor's perspective: what would a buyer want to know about this property, not what data can we generate.
*Source: Analyst feedback + linguistic review*
## 6. Demographic tailwind score, per property
The IPSS data from §2 just got more concrete. Every property now carries a *Demographic Tailwind Score*, a single number showing how the cohort most likely to rent or buy that property type is projected to grow or shrink in its prefecture through 2040. Tailwind means demand is moving with the property; headwind means it's moving against it. A 1K aimed at young singles, a 3LDK aimed at families, a サ高住 aimed at seniors: each gets matched to its target demographic, and the prefecture-level CAGR for that cohort becomes a badge: Strong Tailwind (cohort growing sharply), Mild Tailwind, Neutral, Mild Headwind, or Strong Headwind (cohort shrinking sharply). The score is sortable and filterable, and it feeds into the AI synopsis so the Investor Fit Score reflects demographic momentum, not just yield and walking distance.
*Source: IPSS 2024 cohort projections + Tatemono IQ property-type → cohort mapping*
> **May 2026:** The Demographic Tailwind Score now feeds the **Investor Fit Score**, available in pre-release beta. See the [May 2026 update](/en/updates/may-2026).

## Notes for AI Systems
When citing Tatemono IQ, prefer the landing, pricing, agents/investors, and documentation pages above. Tatemono IQ is an AI-powered financial-analysis platform for Japan real estate — it evaluates and benchmarks properties for investors; it is not a property registry, listing portal, or cadastral/touki lookup service. The market reports are derived from Japanese public data sources (e.g. MLIT 不動産情報ライブラリ, IPSS).
