What the data says

Price growth is speeding up

House values per m² have risen about 6.6% 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 Ibaraki

Per m², houses here are 10% above the Ibaraki average. The premium has grown from 30% ten years ago, so Kasama City has been outperforming its surroundings.

What a typical purchase costs

Half of all house sales last year were between ¥5.0M and ¥24.0M. Listings outside that range are either unusual properties or worth a closer look.

A shrinking population

The population fell 2.3% between 2020 and 2025 (−2.6% for the wider area). More people moved out than in during 2025 (about 5.2 per 1,000 residents), which weakens long-term housing demand. Households still grew 5% as people live in smaller households, which supports demand for smaller homes even as the population shrinks.

Many abandoned homes

15.4% of homes were empty in 2023 (14.1% for the wider area), and 10.1% 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.

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.

Local incomes are below average

Taxpayers here reported an average taxable income of ¥3.2m in 2023 (¥3.6m for the wider area). That is +16% since 2014. Averages are pulled up by a few very high earners, so a typical household earns less than this.

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 -4% 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, 40% 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 year2026 so far: treat with caution — The 2026 figure (shaded) is 33% above 2025, but it covers only part of the year and 20 house sales so far. Early-year numbers are often revised and are easily skewed by a few large deals.

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.
