What the data says
The trend has turned down
After rising earlier, house prices per m² have slipped by about 0.5% a year over the last five years. That often reflects weaker local demand, so check vacancy and population trends before buying.
Lagging Kanagawa
Per m², houses here are 64% below the Kanagawa average. Ten years ago the gap was 56%, so Aikawa Town, Aiko County has been falling behind the rest of Kanagawa.
What a typical purchase costs
Half of all house sales last year were between ¥9.6M and ¥25.8M. 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 (−0.5% for the wider area). More people moved in than out in 2025, a net gain of about 2.2 per 1,000 residents, so demand for homes is being topped up by newcomers. Households still grew 4.4% as people live in smaller households, which supports demand for smaller homes even as the population shrinks.
Few abandoned homes
8.3% of homes were empty in 2023 (9.8% for the wider area), and 2.8% were empty without being for rent, for sale or used as second homes. Most empty homes here are rentals between tenants, not abandoned houses, a sign of a healthy market.
Moderate earthquake risk
The government's seismic model gives a 43% chance of shaking of intensity 6-lower or stronger in the next 30 years (56% 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. 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, 22% are in a landslide warning area. 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.
