What the data says
A long, slow decline
House prices per m² have been falling for a decade, by about 4.8% a year recently. Prices are low, but resale values are likely to keep easing, so buy here to live, not as an investment.
Outperforming Wakayama
Per m², houses here are 6% below the Wakayama average. The discount has shrunk from 18% ten years ago, so Shirahama Town, Nishimuro County is catching up with its surroundings.
Sales are thinning out
Transactions are down about 24% 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 ¥1.4M and ¥17.5M. Listings outside that range are either unusual properties or worth a closer look.
A shrinking population
The population fell 9% between 2020 and 2025 (−6.3% for the wider area). More people moved out than in during 2025 (about 3.1 per 1,000 residents), which weakens long-term housing demand.
Many abandoned homes
43.2% of homes were empty in 2023 (21.3% for the wider area), and 15.7% 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 17.7% of homes are second homes, which points to a resort or holiday-home market.
High earthquake risk
The government's seismic model gives a 69% chance of shaking of intensity 6-lower or stronger in the next 30 years (59% 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 still falling
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, 40% are in a tsunami inundation zone, 40% 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.
