What the data says
A long, slow decline
House prices per m² have been falling for a decade, by about 9.2% a year recently. Prices are low, but resale values are likely to keep easing, so buy here to live, not as an investment.
Lagging Yamaguchi
Per m², houses here are 65% below the Yamaguchi average. Ten years ago the gap was 51%, so Suooshima Town, Oshima County has been falling behind the rest of Yamaguchi.
What a typical purchase costs
Half of all house sales last year were between ¥1.1M and ¥5.0M. Listings outside that range are either unusual properties or worth a closer look.
A shrinking population
The population fell 13.1% between 2020 and 2025 (−5.8% for the wider area). Moves in and out roughly balanced in 2025.
Moderate earthquake risk
The government's seismic model gives a 41% chance of shaking of intensity 6-lower or stronger in the next 30 years (12% for the wider area). Post-1981 buildings are designed for this level of shaking, but check ground conditions and insurance.
