What the data says
A long, slow decline
House prices per m² have been falling for a decade, by about 11.5% a year recently. Prices are low, but resale values are likely to keep easing, so buy here to live, not as an investment.
Lagging Gunma
Per m², houses here are 64% below the Gunma average. Ten years ago the gap was 25%, so Tomioka City has been falling behind the rest of Gunma.
Being near a station is worth a lot
Houses within a 5-minute walk of a station sell for about 20% more per m² than those 11–15 minutes away. If budget is tight, a longer walk is the quickest way to cut the price.
Sales are thinning out
Transactions are down about 11% 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 ¥3.7M and ¥19.0M. Listings outside that range are either unusual properties or worth a closer look.
A shrinking population
The population fell 7.7% between 2020 and 2025 (−3.7% for the wider area). Moves in and out roughly balanced in 2025.
Many abandoned homes
16.3% of homes were empty in 2023 (16.7% for the wider area), and 9.9% 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.
Lower earthquake risk
The government's seismic model gives a 3% 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.
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 -6% over five years. Because these sites don't change, this is the cleanest measure of land value trends.
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.
