May 2026 — Investor Fit Score, market maps, and commercial signals

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.

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.

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.

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.

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.
