What the data says

A long, slow decline

House prices per m² have been falling for a decade, by about 2.2% a year recently. Prices are low, but resale values are likely to keep easing, so buy here to live, not as an investment.

Lagging Chiba

Per m², houses here are 68% below the Chiba average. Ten years ago the gap was 56%, so Kamogawa City has been falling behind the rest of Chiba.

Sales are thinning out

Transactions are down about 18% 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 ¥2.4M and ¥27.0M. Listings outside that range are either unusual properties or worth a closer look.

A shrinking population

The population fell 9.7% between 2020 and 2025 (−0.4% for the wider area). More people moved out than in during 2025 (about 16.6 per 1,000 residents), which weakens long-term housing demand.

Many abandoned homes

31.3% of homes were empty in 2023 (12.3% for the wider area), and 13.2% 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 7.3% of homes are second homes, which points to a resort or holiday-home market.

High earthquake risk

The government's seismic model gives a 73% chance of shaking of intensity 6-lower or stronger in the next 30 years (63% for the wider area). Check the building's earthquake standard (post-1981, ideally post-2000 for wooden houses) and consider earthquake 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 +0% in the year to January 2026 and +2% over five years. Because these sites don't change, this is the cleanest measure of land value trends.

Significant flood risk

Of the official land-price benchmark sites here, which sit in typical neighbourhoods, 33% are inside the worst-case flood zone, 67% are in a tsunami inundation zone. 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.

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.
