What the data says
The trend has turned down
After rising earlier, house prices per m² have slipped by about 1.8% a year over the last five years. That often reflects weaker local demand, so check vacancy and population trends before buying.
Lagging Nagano
Per m², houses here are 25% below the Nagano average. Ten years ago the gap was 18%, so Komagane City has been falling behind the rest of Nagano.
What a typical purchase costs
Half of all house sales last year were between ¥4.0M and ¥16.5M. Listings outside that range are either unusual properties or worth a closer look.
A shrinking population
The population fell 4.1% between 2020 and 2025 (−4.5% for the wider area). Moves in and out roughly balanced in 2025. Households still grew 3.6% as people live in smaller households, which supports demand for smaller homes even as the population shrinks.
Typical vacancy
17.2% of homes were empty in 2023 (20.1% for the wider area), and 7.6% were empty without being for rent, for sale or used as second homes. The level of abandoned homes is around the national norm.
Moderate earthquake risk
The government's seismic model gives a 31% chance of shaking of intensity 6-lower or stronger in the next 30 years (20% for the wider area). Post-1981 buildings are designed for this level of shaking, but check ground conditions and insurance.
Little exposure to flooding
Very few of the official benchmark sites here fall in flood, tsunami or landslide zones, so most typical neighbourhoods are outside mapped hazard areas.

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.
