Natural hazard exposure by city and ward (trial)
We check whether the residential official land-price sites (Chika Koji) fall inside MLIT's designated hazard zones: floods from the largest assumed rainfall on rivers designated by the national or prefectural government (small rivers, inland flooding and storm surge are not included), landslide warning zones designated by the prefecture, and tsunami inundation zones. The sites are representative residential locations, not individual properties; check the municipal hazard map for a specific property.
Checking is being extended across Japan week by week. Only cities and wards where every residential site has been checked and there are at least 5 sites are listed. All municipalities are ranked on the Japanese page.
