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.
Paste the address in Japanese — the form your listing or agent uses. The check itself is free.
- 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 intensity, 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
- Paste the property's Japanese address and check it for free.

- 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.
