What the data says

A shrinking population

The population fell 9.2% between 2020 and 2025 (−0.4% for the wider area). Moves in and out roughly balanced in 2025.

High earthquake risk

The government's seismic model gives a 75% 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.

Local incomes are below average

Taxpayers here reported an average taxable income of ¥3.1m in 2023 (¥4.1m for the wider area). That is +14% since 2014. Averages are pulled up by a few very high earners, so a typical household earns less than this.

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.
