What the data says
Lagging Yamagata
Per m², houses here are 59% below the Yamagata average. Ten years ago the gap was 48%, so Nagai City has been falling behind the rest of Yamagata.
Station distance barely matters
Houses 11–15 minutes from a station sell for similar or higher prices than those near one, which usually means buyers here drive or value quiet residential streets.
What a typical purchase costs
Half of all house sales last year were between ¥1.0M and ¥8.0M. Listings outside that range are either unusual properties or worth a closer look.
A shrinking population
The population fell 7.4% between 2020 and 2025 (−7% for the wider area). More people moved out than in during 2025 (about 6 per 1,000 residents), which weakens long-term housing demand. Households still grew 1.3% as people live in smaller households, which supports demand for smaller homes even as the population shrinks.
Typical vacancy
14% of homes were empty in 2023 (13.6% for the wider area), and 7.4% were empty without being for rent, for sale or used as second homes. The level of abandoned homes is around the national norm.
Lower earthquake risk
The government's seismic model gives a 3% chance of shaking of intensity 6-lower or stronger in the next 30 years (5% for the wider area). This is low by Japanese standards, although no part of Japan is free of earthquake risk.
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 -1% 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.

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.
