What the data says

Price growth is speeding up

House values per m² have risen about 5.6% a year over the past five years, faster than the 0% a year of the five years before. Buyers waiting for a dip have so far been paying more each year, and that has not yet changed.

Outperforming Kumamoto

Per m², houses here are 26% below the Kumamoto average. The discount has shrunk from 32% ten years ago, so Arao City is catching up with its surroundings.

Sales are thinning out

Transactions are down about 14% 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 ¥3.6M and ¥19.0M. Listings outside that range are either unusual properties or worth a closer look.

A shrinking population

The population fell 6.9% between 2020 and 2025 (−3.5% for the wider area). Moves in and out roughly balanced in 2025.

Many abandoned homes

17.8% of homes were empty in 2023 (14.9% for the wider area), and 11.5% 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.

Lower earthquake risk

The government's seismic model gives a 8% chance of shaking of intensity 6-lower or stronger in the next 30 years (15% for the wider area). This is low by Japanese standards, although no part of Japan is free of earthquake risk.

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 +0% 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, 25% 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.

Median transaction price by yearA sharp recent rise — The median house price rose 40% between 2023 and 2025. Prices per m² rose 85% too, so this is a genuine like-for-like increase, not just bigger homes selling. With only 35 house sales in 2025, a handful of expensive deals can move the median a lot.

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.
