What the data says

The trend has turned down

After rising earlier, house prices per m² have slipped by about 6.6% a year over the last five years. That often reflects weaker local demand, so check vacancy and population trends before buying.

Lagging Gunma

Per m², houses here are 23% above the Gunma average. The premium was 30% ten years ago, so the rest of Gunma has been catching up.

Station distance barely matters

Houses 11–15 minutes from a station sell for similar or higher prices than those near one, which usually means buyers here drive or value quiet residential streets.

Sales are thinning out

Transactions are down about 14% 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 ¥7.1M and ¥27.0M. Listings outside that range are either unusual properties or worth a closer look.

A shrinking population

The population fell 1.6% between 2020 and 2025 (−3.7% for the wider area). More people moved in than out in 2025, a net gain of about 2.9 per 1,000 residents, so demand for homes is being topped up by newcomers. Households still grew 3.1% as people live in smaller households, which supports demand for smaller homes even as the population shrinks.

Typical vacancy

13.9% of homes were empty in 2023 (16.7% for the wider area), and 5.1% 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 23% 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.

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. They are still 57% below their 1991 bubble-era level. 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, 51% are inside the worst-case flood zone (6% 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.

Price per m² by building age (2021–2025 sales)Houses bottom out at around 25 years — House prices per m² drop about 69% from new by age 25, then flatten, because by then buyers are mostly paying for the land. A house older than that costs little more than its plot, a good option if you plan to renovate or rebuild.

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.
