What the data says
Steady, predictable growth
House prices per m² have climbed about 1.4% a year, roughly in line with the previous five years. There is no sign of overheating or a sudden slowdown.
Lagging Kanagawa
Per m², houses here are 31% below the Kanagawa average. Ten years ago the gap was 24%, so Samukawa Town, Koza County has been falling behind the rest of Kanagawa.
A modest station premium
Houses within a 5-minute walk of a station sell for about 5% more per m² than those 11–15 minutes away. The penalty for a longer walk is mild, so it is worth widening your search radius.
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 ¥20.0M and ¥41.0M. Listings outside that range are either unusual properties or worth a closer look.
A shrinking population
The population fell 0.6% between 2020 and 2025 (−0.5% for the wider area). Moves in and out roughly balanced in 2025. Households still grew 3.6% as people live in smaller households, which supports demand for smaller homes even as the population shrinks.
Few abandoned homes
7.9% of homes were empty in 2023 (9.8% for the wider area), and 3.4% 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.
High earthquake risk
The government's seismic model gives a 66% 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 +2% in the year to January 2026 and +10% 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, 55% are inside the worst-case flood 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.
