What the data says
Price growth is speeding up
Condo values per m² have risen about 9.9% a year over the past five years, faster than the 1.2% 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 Chiba
Per m², condos here are 23% below the Chiba average. The discount has shrunk from 32% ten years ago, so Inzai City is catching up with its surroundings.
Being near a station is worth a lot
Condos within a 5-minute walk of a station sell for about 115% more per m² than those 11–15 minutes away. If budget is tight, a longer walk is the quickest way to cut the price.
A family market
95% 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 38% 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 ¥13.3M and ¥34.8M. Listings outside that range are either unusual properties or worth a closer look.
A growing population
The population grew 7.6% between 2020 and 2025 (−0.4% for the wider area). More people moved out than in during 2025 (about 6.5 per 1,000 residents), which weakens long-term housing demand.
Typical vacancy
11.2% of homes were empty in 2023 (12.3% for the wider area), and 4.1% 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 29 years of the area's median rent (¥68k a month), compared with 33.2 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.
High earthquake risk
The government's seismic model gives a 52% chance of shaking of intensity 6-lower or stronger in the next 30 years (63% for the wider area). Check the building's earthquake standard (post-1981, ideally post-2000 for wooden houses) and consider earthquake insurance.
A typical condo costs 5.5 years of local income
Taxpayers here reported an average taxable income of ¥4.3m in 2023 (¥4.1m for the wider area). That is +16% since 2014. The median resale condo sold for about 5.5 times that, against 5.9 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 rising fast
On the government's fixed benchmark sites, which are valued the same way every year, residential land prices changed +5% in the year to January 2026 and +12% over five years. They are still 78% below their 1991 bubble-era level. 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, 35% are inside the worst-case flood zone (20% with expected depths of 3 m or more). 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.
