Layer the location risks
Japan’s official hazard portal combines national risk layers with links to municipality hazard maps. Review flood, landslide, storm-surge, and tsunami information relevant to the location.
- Check more than one hazard layer
- Open the municipality map too
- Record evacuation routes and local shelters
Inspect the actual building
Confirm roof, foundation, structure, moisture, pests, water supply, drainage, electricity, boundaries, road access, and whether intended work needs permits or specialists.
- Visit after or during bad weather when possible
- Photograph defects with location notes
- Separate urgent safety work from optional design work

Turn a visible mark into an inspection question
For each concern, note the room, exact position, date, photo number, and what remains out of view. Ask an appropriate building professional to check the roof or plumbing above a ceiling mark and describe the repair scope. Keep that finding separate from the location risks shown on official hazard maps.
Important caution
Online maps and remote video are screening tools, not guarantees. Boundaries, structure, legal restrictions, and repairability need case-specific confirmation.
