What the data says
Steady, predictable growth
Condo prices per m² have climbed about 2.2% a year, roughly in line with the previous five years. There is no sign of overheating or a sudden slowdown.
Lagging Saitama
Per m², condos here are 56% below the Saitama average. Ten years ago the gap was 45%, so Iruma City has been falling behind the rest of Saitama.
A modest station premium
Condos within a 5-minute walk of a station sell for about 8% 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.
A family market
76% of recent condo sales have three or more bedrooms. Demand comes mainly from owner-occupier families, which tends to make prices steadier but rental yields lower.
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 condo sales last year were between ¥6.0M and ¥15.5M. 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 (−0.8% for the wider area). Moves in and out roughly balanced in 2025. Households still grew 1.5% as people live in smaller households, which supports demand for smaller homes even as the population shrinks.
Typical vacancy
8.1% of homes were empty in 2023 (9.3% for the wider area), and 4% were empty without being for rent, for sale or used as second homes. The level of abandoned homes is around the national norm.
Buying vs renting
A median used condo costs about 18.5 years of the area's median rent (¥54k a month), compared with 33.5 years for the wider area. That is a middle-of-the-road ratio for Japan. Rents here cover all rented homes, so treat this as a rough guide.
Moderate earthquake risk
The government's seismic model gives a 38% chance of shaking of intensity 6-lower or stronger in the next 30 years (52% for the wider area). Post-1981 buildings are designed for this level of shaking, but check ground conditions and insurance.
A typical condo costs 3.4 years of local income
Taxpayers here reported an average taxable income of ¥3.5m in 2023 (¥3.9m for the wider area). That is +11% since 2014. The median resale condo sold for about 3.4 times that, against 6.4 times for the wider area. A higher multiple means prices lean more on buyers from outside the area or on two incomes. Averages are pulled up by a few very high earners, so a typical household earns less than this.
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 +4% over five years. They are still 62% 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, 8% 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.

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.
