What the data says

The trend has turned down

After rising earlier, house prices per m² have slipped by about 5.9% a year over the last five years. That often reflects weaker local demand, so check vacancy and population trends before buying.

Moving with Shiga

Per m², houses here are 47% below the Shiga average. That position has barely changed in ten years, so it moves with the wider market.

Being near a station is worth a lot

Houses within a 5-minute walk of a station sell for about 107% more per m² than those 11–15 minutes away. If budget is tight, a longer walk is the quickest way to cut the price.

Sales are thinning out

Transactions are down about 15% 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 ¥4.6M and ¥18.0M. Listings outside that range are either unusual properties or worth a closer look.

A shrinking population

The population fell 3.8% between 2020 and 2025 (−1.5% for the wider area). More people moved out than in during 2025 (about 3 per 1,000 residents), which weakens long-term housing demand. Households still grew 2.4% as people live in smaller households, which supports demand for smaller homes even as the population shrinks.

Typical vacancy

11.7% of homes were empty in 2023 (12.3% for the wider area), and 6.6% were empty without being for rent, for sale or used as second homes. The level of abandoned homes is around the national norm.

Moderate earthquake risk

The government's seismic model gives a 23% chance of shaking of intensity 6-lower or stronger in the next 30 years (21% 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 +0% in the year to January 2026 and -1% over five years. They are still 54% below their 1991 bubble-era level. 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, 23% 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 jump driven by what sold — The median house price rose 42% between 2023 and 2025. Per m², prices rose only 25%, so most of the jump comes from larger or higher-end properties changing hands, not from the same homes getting that much more expensive. With only 67 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.
