Flood, tsunami and landslide hazard zones (assumed)
Flood (maximum assumed scale): this point is inside a flood-hazard zone, with an assumed depth of 3.0 to 5.0 m. （Hazard Map Portal Site, maximum assumed scale）
Tsunami: this point is outside the tsunami inundation zone even for the largest-class tsunami. （Hazard Map Portal Site, largest class）
Landslide: this point is outside the sediment-disaster hazard area. （National Land Numerical Information A33）
This shows the "maximum assumed scale" zone, a different document from the record of floods that actually happened (a jisseki-zu). Actual-flood records are published separately by each municipality or river authority. Since 28 August 2020, Japanese real-estate transactions have been legally required to show a property's position on the flood hazard map as part of the mandatory disclosure. This screen can be a starting point for that check, but the authoritative source is each municipality's own hazard map. Open the map here with the hazard layers on

If you live here
Hazard zones are a property of the exact address, not of the municipality, so this page does not summarise them. Open the point card for any address, or the map with the hazard layers on.
Outside a zone does not mean safe. The authoritative source is the municipality's own hazard map.
What it costs here
From kurashigram, the sister project that measures prices in Japan from primary sources. Today it reads furusato-nozei (hometown tax) return goods listed by this municipality and normalises them to grams per 10,000 yen.
