Japan has approximately 9 million vacant houses (akiya / 空き家) — nearly 14% of all housing stock. Social media makes it look like you can buy a house for the price of a dinner. But what's happening to land values in these areas? We analyzed the 2026 official land price data for Japan's highest vacancy-rate prefectures. The answer reveals a sharply divided market.
Land is the only component of Japanese real estate that can appreciate — buildings depreciate by tax code (22 years for wood, 47 for RC). So when you buy an akiya, the investment case rests entirely on what the land underneath is doing. Here's what the 2026 government data shows.
Japan's Highest Akiya Rate Prefectures — Land Price Trends
The prefectures with the highest vacancy rates are, overwhelmingly, the ones where land prices are falling.
| Prefecture | Akiya Rate | 2026 Land Price Trend | Avg Price/m² | Verdict |
|---|---|---|---|---|
| Tokushima | ~21% | Declining | Low | Falling market |
| Wakayama | ~20% | Declining | Low | Falling market |
| Yamanashi | ~20% | Mixed | Low–Mid | Mixed signals |
| Ehime | ~19% | Declining | Low | Falling market |
| Kagoshima | ~19% | -0.36% (2026) | Low | Falling market |
| Shimane | ~18% | -0.46% (2026) | Low | Weakest in Japan |
| Niigata | ~17% | -0.41% (2026) | Low | Falling market |
| Akita | ~16% | Declining | Low | Fastest depopulation |
Vacancy rates: Ministry of Internal Affairs and Communications Housing and Land Survey (住宅・土地統計調査, 2023). Land price trends: MLIT 2026 Official Land Price Survey (令和8年地価公示).
A clear pattern emerges: the regions with the most akiya are the regions where land prices are declining. This is not a coincidence. Population outflow, aging demographics, and lack of economic activity drive both phenomena. Fewer people means less demand for housing means lower land prices means more vacant houses — a self-reinforcing cycle.
Shimane posted the worst prefecture-wide performance in 2026 at -0.46%, with its weakest survey point (Tsuwano) dropping -4.8%. Akita has the fastest population decline in Japan — losing residents at a rate where some municipalities may become administratively non-viable within two decades.
For buyers considering akiya in these prefectures: the land under your house is losing value every year. Your total asset — building (already worthless) + land (declining) — is depreciating from day one. That doesn't make it a bad lifestyle choice, but it makes it a poor financial investment.

The Exceptions — Akiya Regions Where Land IS Rising
Not all areas with akiya availability have declining land. A small but important group of regions combines vacant house stock with appreciating land — driven by external demand that overrides local population decline.
| Area | Has Akiya? | 2026 Land Price Trend | Why Different |
|---|---|---|---|
| Niseko / Kutchan (Hokkaido) | Yes (surrounding areas) | +12.32% | International ski tourism, 15+ years of foreign investment |
| Hakuba (Nagano) | Yes (village outskirts) | +26.9% | International ski/outdoor demand, Australian + North American community |
| Okinawa islands | Yes (some inland areas) | +6.52% (pref avg) | Year-round tourism + US military presence |
| Chitose (Hokkaido) | Yes (some areas) | +44.1% | Rapidus semiconductor plant + airport hub |
| Karuizawa (Nagano) | Limited | +9.83% | Tokyo weekend retreat, high-end lifestyle demand |
| Fukuoka suburbs | Yes | +3–5% | Japan's fastest-growing major city |
These are the exceptions that prove the rule. In all cases, external demand — international tourism, semiconductor industry, military presence, metropolitan spillover — is overriding the local population decline. Akiya in these areas may sit on appreciating land, but they tend to be priced accordingly and move quickly.
In Niseko, land that cost ¥18,000/m² in 2016 is government-appraised at ¥189,000/m² in 2026 — a 950% increase in 10 years. Surrounding areas still have affordable vacant properties, but the gap between a ¥2M akiya 10km from the lifts and ¥130M development land in Hanazono is enormous.

The Two-Speed Map — Urban vs Rural Japan
The 2026 land price data confirms what the past decade has been showing: Japan is not one real estate market. It is two markets moving in opposite directions.
Rising (2026 MLIT Official Land Prices)
| Area | YoY Change |
|---|---|
| Chitose, Hokkaido | +44.1% |
| Hakuba, Nagano | +26.9% |
| Kutchan / Niseko | +12.32% |
| Karuizawa | +9.83% |
| Tokyo (avg) | +8.22% |
| Okinawa (avg) | +6.52% |
| Fukuoka (avg) | +6.3–6.9% |
| Chiba (avg) | +4.87% |
| Osaka (avg) | +4.20% |
Falling (2026 MLIT Official Land Prices)
| Area | YoY Change |
|---|---|
| Shimane | -0.46% |
| Niigata | -0.41% |
| Kagoshima | -0.36% |
| Akita | -0.32% |
| Aomori | -0.28% |
The national average of +2.8% masks this divide entirely. Japan's strong overall number is driven by surging metropolitan and resort areas pulling up a national figure that includes hundreds of declining rural towns.
The 9 million akiya are overwhelmingly in the falling market. The areas tracked by JRE — major city centers, resort markets with international demand, and emerging industrial hubs — are in the rising market. Knowing which side you're investing in is the most important decision you'll make.

How to Evaluate Land in an Akiya Area
Four checks before buying any akiya:
1. Check the official land price trend
The MLIT publishes official land prices (公示地価) at 25,565 survey points annually. If your target area shows declining prices, every year you hold the property, the land underneath loses value. This is the single most important data point for an akiya investment decision.
2. Check MLIT transaction data
Are there actual completed sales in the area over the past 2–3 years? MLIT records show what buyers really paid. If transaction volume is zero or near-zero, that's a severe liquidity warning: you may be able to buy, but you may never be able to sell.

3. Check population trend
Japan's population is declining nationally (-0.5% per year), but the impact is deeply uneven. Tokyo is still growing. Akita is losing 1.5% per year. A town losing 1–2% of its population annually will lose 15–20% of its residents within a decade — and with them, the schools, shops, medical facilities, and infrastructure that make a town livable.
4. Look for external demand drivers
The akiya regions where land IS rising all share one trait: demand from outside the local population. International tourism (Niseko, Hakuba, Okinawa), semiconductor industry (Chitose), military presence (Okinawa), or metropolitan spillover (Fukuoka suburbs, Karuizawa) creates buying pressure that local demographics alone cannot generate.
If your target area has none of these external drivers, the investment case relies entirely on local demand — which, in high-vacancy areas, is by definition insufficient to absorb existing housing stock.
What This Means for Foreign Investors
If you're attracted to Japan by the akiya stories, you're not wrong that Japan offers extraordinary value compared to other developed countries. Japan has zero restrictions on foreign property ownership — no approval process, no foreign buyer tax, no residency requirement. That's genuinely rare among developed economies.
But the value is in different places depending on your goal:
Lifestyle / personal use — Akiya can be excellent. The renovation process is challenging but rewarding for hands-on buyers. Buy for enjoyment, not financial returns. Budget the full cost realistically: acquisition + renovation + 3 years of maintenance. See our full akiya cost breakdown.
Investment / income — Focus on areas where land is appreciating and rental demand exists. These are the 20+ areas JRE tracks, with actual MLIT transaction data to back your decisions. The akiya vs urban condo comparison lays out the numbers.
Hybrid — Target akiya specifically in Top Tier areas where land is rising. This combines the akiya price advantage with appreciating fundamentals. These opportunities exist but they move fast — the market is efficient enough that undervalued properties in rising areas don't sit for long.
