What the data says
A shrinking population
The population fell 13.2% between 2020 and 2025 (−0.4% for the wider area). More people moved in than out in 2025, a net gain of about 7 per 1,000 residents, so demand for homes is being topped up by newcomers.
High earthquake risk
The government's seismic model gives a 67% chance of shaking of intensity 6-lower or stronger in the next 30 years (63% for the wider area). Check the building's earthquake standard (post-1981, ideally post-2000 for wooden houses) and consider earthquake insurance.

About this data
Figures are medians of real transactions reported to Japan's Ministry of Land, Infrastructure, Transport and Tourism (MLIT) through its quarterly price survey. House prices per m² divide the total price (land and building) by the floor area. Medians based on fewer than 20 sales are not shown. The latest quarters are preliminary and are revised as more survey responses arrive.
