What the data says

A shrinking population

The population fell 7.9% between 2020 and 2025 (−6% for the wider area). More people moved out than in during 2025 (about 7.7 per 1,000 residents), which weakens long-term housing demand.

Many abandoned homes

16.9% of homes were empty in 2023 (15.3% for the wider area), and 10.4% were empty without being for rent, for sale or used as second homes. That is a high share of truly abandoned homes (akiya), a sign of weak demand. Cheap houses are easy to find, but resale can be slow.

Lower earthquake risk

The government's seismic model gives a 7% chance of shaking of intensity 6-lower or stronger in the next 30 years (12% for the wider area). This is low by Japanese standards, although no part of Japan is free of earthquake risk.

Local incomes are close to average

Taxpayers here reported an average taxable income of ¥2.9m in 2023 (¥3.2m for the wider area). That is +19% 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.
