THE PRICE IS NOT THE COST
Know the full cost before you contact the agent
Drop in a maisoku PDF, or capture a listing with one click. The full cost breakdown comes back with it.
The asking price is the number you see. It is not the number you pay.
Tatemono IQ reads any Japanese listing and breaks down the price, fees, taxes, and running costs, then shows you the yield that survives them.

Every cost the listing leaves out
Two real listings, a Tokyo condo and a Fukuoka one, with the acquisition costs neither flyer totals.
Two real analyses of the synthetic pair. A ¥24,800,000 Tokyo listing carries ¥2,001,200 in acquisition costs, 8.1% above the asking price, for an all-in ¥26,801,200. A ¥7,200,000 Fukuoka listing carries ¥683,800, or 9.5%. The smaller price carries the larger share, which is why a cheap listing is not automatically a cheap purchase.
The price is the one cost a listing reliably tells you.
Brokerage, registration, acquisition tax, insurance, loan fees, and the monthly reserve all arrive after you have already decided you are interested. Each one is standard, each one is knowable in advance, and almost none of them appear on the flyer. Tatemono IQ totals them at the point you are still deciding whether to ask.
A yield calculated on the asking price is a yield calculated on the wrong number.
Gross yield divides rent by the sticker price. The money you actually commit includes everything the sticker leaves out, and the running costs come off the rent every month after that. The gap between the two figures is the difference between a property that works and one that does not.
Ask what it costs, not what it lists for.
What it does
Tatemono IQ reads the Japanese-language documents behind a property, pulls in official land and tax data, and gives you one clear page per property: yield, comparables, and the legal and structural risks flagged before you commit.
Translate & structure
Reads and structures the Japanese documents (maisoku, listing) into one view.
Score & rank
Scores and ranks properties side by side on yield and risk, not gut feel.
Catch what the listing does not say
Flags legal, leasehold, and seismic concerns before you commit.
Export & share
Exports a shareable evaluation you can hand to partners. Viewable by link, no account needed.
Every property distilled to one clear verdict page, including a calculated 2.77% real net yield.
Natural-disaster exposure scored per site before you commit: overall Low Risk, one Moderate flood flag, and None for tsunami and landslide.
Everything you need to evaluate a Japan property, without flying there.
Capture any listing in one click
Stop retyping listing data. Open any property on SUUMO, Athome, Rakumachi and 10 more portals, and it's imported and structured instantly.
See the numbers that actually decide the deal
Long-term cashflow modeling with financing, depreciation, vacancy, and exit scenarios (loan term configurable up to 35 years). The real return, not a one-line gross yield.
Flood, tsunami, landslide, and storm-surge exposure scored for due diligence. Before you commit, not after.
Street View, walking times, and 41 points-of-interest categories. Judge the location from anywhere.
Shortlist with confidence
Organize properties into lists, rank them by AI cash-flow, and compare side by side instead of juggling a folder of PDFs.
Make it personal, and get answers fast
Tell it your strategy (budget, target return, risk tolerance, horizon) and every property comes back with a personalized fit score.
Ask anything in plain language. Track the questions you send brokers, record their answers, and auto-apply them to the property.

In a data-rich market, judgment is the edge.
What matters isn't how much information you have. It's whether you can organize it, compare it, and stand behind the decision. Tatemono IQ is the foundation under that judgment.
What reduces regret isn't more information. It's better judgment.
