What the data says
What a typical purchase costs
Half of all house sales last year were between ¥6.0M and ¥24.0M. Listings outside that range are either unusual properties or worth a closer look.
A shrinking population
The population fell 7.7% between 2020 and 2025 (−0.4% for the wider area). More people moved out than in during 2025 (about 3.6 per 1,000 residents), which weakens long-term housing demand. Households still grew 2% as people live in smaller households, which supports demand for smaller homes even as the population shrinks.
Moderate earthquake risk
The government's seismic model gives a 35% chance of shaking of intensity 6-lower or stronger in the next 30 years (63% for the wider area). Post-1981 buildings are designed for this level of shaking, but check ground conditions and insurance.

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.
