What the data says
The trend has turned down
After rising earlier, house prices per m² have slipped by about 7.8% a year over the last five years. That often reflects weaker local demand, so check vacancy and population trends before buying.
Lagging Yamaguchi
Per m², houses here are 35% below the Yamaguchi average. Ten years ago the gap was 20%, so San-yoonoda City has been falling behind the rest of Yamaguchi.
Sales are thinning out
Transactions are down about 22% on the previous three years. Fewer sales mean less choice and slower resale, so allow more time to sell later.
What a typical purchase costs
Half of all house sales last year were between ¥1.9M and ¥19.0M. Listings outside that range are either unusual properties or worth a closer look.
A shrinking population
The population fell 6.2% between 2020 and 2025 (−5.8% for the wider area). More people moved out than in during 2025 (about 2.2 per 1,000 residents), which weakens long-term housing demand.
Many abandoned homes
16.7% of homes were empty in 2023 (19.4% for the wider area), and 10.1% 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 10% 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 ¥3.2m in 2023 (¥3.4m for the wider area). That is +18% since 2014. Averages are pulled up by a few very high earners, so a typical household earns less than this.
Official land prices are edging up
On the government's fixed benchmark sites, which are valued the same way every year, residential land prices changed +0% in the year to January 2026 and +2% over five years. Because these sites don't change, this is the cleanest measure of land value trends.
Some flood or landslide exposure
Of the official land-price benchmark sites here, which sit in typical neighbourhoods, 57% are inside the worst-case flood zone (14% with expected depths of 3 m or more). 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.
