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.

📍 Open the point card at the centre of this municipality (flood, tsunami, storm surge, landslide) 🗺 Open KUON MAP here with flood, tsunami and landslide layers

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.
