The disaster profile of one Japanese property, in English.
Japan publishes excellent hazard data — in Japanese. This report reads it for you: a print-ready document on the specific address you're buying or renting, built from official government sources, with every value cited. Check the address for free first; buy only if you want the full report.
A home inspection in Japan costs ¥50,000–100,000 and requires someone to physically visit. This report sits one step earlier — the decision about the land, which an inspection cannot answer — and needs nobody on site. It is priced at roughly a third of the cheapest inspection.
It contains a stated verdict on the disaster axis with the conditions that would need to be met, an estimated loss in yen and what that works out to per year, historical aerial photographs back to the 1940s showing what the land used to be, a ground-elevation profile including how far you would have to travel to reach ground 5m higher, earthquake insurance priced in yen from the rates published by Japan's Ministry of Finance, and the questions for the seller written out in Japanese so your agent can send them as they are.
Choosing between candidates? Two properties compared side by side, with a stated conclusion, is $199 — and three is $269 — less than buying the reports separately, with the comparison included.
Paste the Japanese address from your listing, or just type it in English letters (e.g. "shinjuku kabukicho 1-1"). Either way, we resolve it to an exact point — confirm the resolved location before you buy. The check itself is free.
Enter two or three addresses and you get the full report on each, plus a comparison that reaches a conclusion: which one is better on the disaster axis, what the difference costs you in insurance over 30 years, and what would have to be true for the weaker one to still work. Delivered on screen and by email immediately after checkout.
Enter at least two addresses.
- Flood — expected depth at the property, and how long the water is expected to take to recede
- House-collapse zones — overflow-current and bank-erosion designations (whether staying home is even an option)
- Earthquake — 30-year probabilities by shindo — Japan's 0–7 shaking-intensity scale — plus the ground beneath the property (landform, amplification)
- Liquefaction — susceptibility and the landform history behind it
- Landslide / Tsunami / Storm surge — designated-zone checks for each
- Elevation & terrain — the property's elevation in context
- What to do — neutral, practical notes — evacuation thinking, insurance points to check, questions for your agent
- Type the address in English letters or paste the Japanese one — the free check resolves it to an exact point.
- Pay $120 by card (Stripe secure checkout, USD).
- The report opens immediately, and the same link is emailed to you (valid ~6 months).
- Save it as a PDF with the report's print button.
Reports are generated deterministically from the sources — no AI-written guesses. The same address always yields the same assessment.
mamoie states facts from official open data (Overlay Hazard Map, J-SHIS and others) and always cites the source. The report is reference information, not a guarantee of safety or investment/insurance advice. Resolution is map-pixel / ~250m mesh. See data sources.
