What drives Japan's disaster profile
Across the 30 Japan cities in our data, the three highest average exposures are earthquake (4.5/5), storms (hurricane/cyclone) (4.5/5) and tsunami (3.7/5). These reflect geography rather than chance: earthquake tiers come from real USGS records of magnitude-4.5+ events within 300 km, storm risk from position in a tropical-cyclone basin, flood from rainfall regime and low-lying terrain, and wildfire/heat from Köppen climate zone. The full modelled profile for Japan is earthquake 4.5/5; storms (hurricane/cyclone) 4.5/5; tsunami 3.7/5; flooding 3.4/5; extreme heat 2.2/5; extreme cold / winter 2.2/5; wildfire 2.0/5; drought 1.0/5. Use it as a relative guide between cities — a high tier means plan for it (insurance, building codes, location within the city), not that disaster is certain. City pages break each hazard down individually.
Japan disaster exposure by type
- earthquake: 4.5/5 — high — plan, insure and check building codes for it.
- storms (hurricane/cyclone): 4.5/5 — high — plan, insure and check building codes for it.
- tsunami: 3.7/5 — moderate — worth verifying for your specific neighbourhood.
- flooding: 3.4/5 — moderate — worth verifying for your specific neighbourhood.
- extreme heat: 2.2/5 — low — a minor consideration.
- extreme cold / winter: 2.2/5 — low — a minor consideration.
- wildfire: 2.0/5 — low — a minor consideration.
- drought: 1.0/5 — negligible in our model.
For relocators, the practical takeaway is to match the hazard profile to your housing choice: where flood or storm tiers are elevated, favour higher ground and modern drainage; where the earthquake tier is high, prioritise post-code seismic construction; and budget for the insurance lines that the leading hazards in Japan will drive. The safest single city in our Japan sample, Sapporo (safety 58/100), is the natural starting point if low disaster exposure is your top filter.
