What the data says
Steady, predictable growth
House prices per m² have climbed about 0.3% a year, roughly in line with the previous five years. There is no sign of overheating or a sudden slowdown.
Moving with Aichi
Per m², houses here are 21% below the Aichi average. That position has barely changed in ten years, so it moves with the wider market.
Sales are thinning out
Transactions are down about 10% 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 ¥16.0M and ¥30.0M. Listings outside that range are either unusual properties or worth a closer look.
A stable population
The population was roughly stable between 2020 and 2025 (−1.2% for the wider area). More people moved in than out in 2025, a net gain of about 4.3 per 1,000 residents, so demand for homes is being topped up by newcomers.
Typical vacancy
12.6% of homes were empty in 2023 (11.8% for the wider area), and 4.9% were empty without being for rent, for sale or used as second homes. The level of abandoned homes is around the national norm.
High earthquake risk
The government's seismic model gives a 72% chance of shaking of intensity 6-lower or stronger in the next 30 years (56% 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 +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.
Some flood or landslide exposure
Of the official land-price benchmark sites here, which sit in typical neighbourhoods, 100% are inside the worst-case flood zone (14% 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.

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.
