What the data says
A shrinking population
The population fell 6% between 2020 and 2025 (−6.1% 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. Households still grew 0.4% as people live in smaller households, which supports demand for smaller homes even as the population shrinks.
Many abandoned homes
23.1% of homes were empty in 2023 (21.3% for the wider area), and 10.9% 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.
High earthquake risk
The government's seismic model gives a 77% chance of shaking of intensity 6-lower or stronger in the next 30 years (75% 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 close to average
Taxpayers here reported an average taxable income of ¥3.2m in 2023 (¥3.4m for the wider area). That is +16% since 2014. Averages are pulled up by a few very high earners, so a typical household earns less than this.
Official land prices are still falling
On the government's fixed benchmark sites, which are valued the same way every year, residential land prices changed -1% in the year to January 2026 and -4% over five years. Because these sites don't change, this is the cleanest measure of land value trends.
Significant flood risk
Of the official land-price benchmark sites here, which sit in typical neighbourhoods, 100% are inside the worst-case flood zone, 80% are in a tsunami inundation zone. Most worst-case flood zones are shallow (under 0.5 m) at the edges, so depth matters as much as the share. Check the hazard map for any specific address before buying.

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.
