What the data says
Price growth is speeding up
House values per m² have risen about 4.3% a year over the past five years, faster than the 3.1% a year of the five years before. Buyers waiting for a dip have so far been paying more each year, and that has not yet changed.
Lagging Nagano
Per m², houses here are 34% below the Nagano average. Ten years ago the gap was 24%, so Komoro City has been falling behind the rest of Nagano.
What a typical purchase costs
Half of all house sales last year were between ¥5.5M and ¥25.0M. Listings outside that range are either unusual properties or worth a closer look.
A shrinking population
The population fell 1.9% between 2020 and 2025 (−4.5% for the wider area). Moves in and out roughly balanced in 2025. Households still grew 2.8% as people live in smaller households, which supports demand for smaller homes even as the population shrinks.
Many abandoned homes
24.3% of homes were empty in 2023 (20.1% for the wider area), and 10.3% 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. About 3.6% of homes are second homes, which points to a resort or holiday-home market.
Lower earthquake risk
The government's seismic model gives a 12% chance of shaking of intensity 6-lower or stronger in the next 30 years (20% for the wider area). This is low by Japanese standards, although no part of Japan is free of earthquake risk.
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 +1% in the year to January 2026 and +1% over five years. Because these sites don't change, this is the cleanest measure of land value trends.

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.
