It's not the language. It's a different investment framework.
A Japanese broker hands over a one-page maisoku and a single gross-yield figure. An international buyer needs NOI, a multi-year pro forma, and municipality-level market context. Both are right: they're reading the same property through entirely different lenses, and cross-border deals die in that gap. Tatemono IQ puts both frameworks on one page, so nothing gets lost between them.
5 Decision Layers
A single overlooked layer, such as a hidden leasehold or an aging structure, can turn a 4.8% gross yield into a real loss. Every analysis checks all five, so nothing slips past you.

Frequently asked questions
Which listing sites does it work with?
The browser extension imports listings from major Japanese portals, including SUUMO, Athome, Rakumachi, Kenbiya and LIFULL HOME'S investment listings. You can also upload any maisoku (broker flyer) PDF, whichever site or agent it came from.
Which languages does it support?
The app is available in English, Japanese, Korean, Simplified Chinese and Traditional Chinese, and you choose the language of each analysis from that same list, whatever language the listing is in.
What happens when my trial ends?
Without a card on file, you are never charged: when the trial ends your plan doesn't start, and your account and data stay open on Pay as you go, where you can buy property or analysis packs or subscribe at any time. If you add a card during the trial, your plan starts and is billed when the trial ends. You can cancel before then with no obligation.
What does an analysis include?
The standard analysis opens with a financial summary (asking price, gross and estimated net yield, building age and structure, seismic standard, and an estimated cost-approach value) and a scorecard. A written assessment covers rental demand, returns, market context and risks, with a favorability label set by a fixed scoring rubric. It closes with what the analysis could not determine and a prioritized list of questions to confirm with the broker. It is an estimate for your own due diligence, not a licensed appraisal.
Is the data official?
Area price benchmarks come from official MLIT transaction-price and land-price data, hazard exposure from the GSI Hazard Map Portal and J-SHIS seismic data, and the demographic outlook from IPSS household projections. Asking price, rent, fees, building details and station walk times come from the listing itself; the market rent level and market commentary are AI estimates. Everything is reference information for your own due diligence, not an appraisal.
Can I share an analysis?
Yes. On every plan you can export an analysis as a PDF and send the file to anyone. On plans for real estate companies (Office, Agency and Brokerage), agents and the team owner can also create a private link to an analysis they created, for one email address: the recipient reads the written analysis after confirming that email, with no account needed, and the link expires after 30 days.
Check a listing's real yield before you inquire.
Capture a listing or upload the Maisoku, and get a structured risk-and-yield report in about a minute, with every number grounded in real market evidence.
