Introduction: The “2025 Problem” Is Rewriting the Japanese Real Estate Map

Japan’s aging society reached a critical milestone in 2025 as its postwar baby boomer generation, born from 1947 to 1949, turned 75 and older, now representing nearly one in five people. This “2025 Problem” accelerates population aging and redefines housing demand nationwide, but its effects are especially pronounced in Tokyo’s commuter belt—including Gunma and Saitama prefectures.

While central Tokyo prices remain high, new opportunities are opening up in well-connected regional hubs. Properties in Gunma and Saitama—known for tranquility, space, and quick train links to the city—are attracting domestic migrators and international buyers alike. This guide breaks down the latest data, trends, and actionable insights for anyone considering buying property in Japan in this new era.

1. Background: How Demographic Shifts Are Shaping Japan’s Housing Market

Japan’s population continues to shrink and age at a world-leading pace. By 2025, over 18% of the country’s residents will be 75 or older, draining labor supply and changing living patterns. This is triggering several crucial market trends:

• Vacant Homes on the Rise: A record-high number of akiya (vacant houses) are appearing, especially in rural and semi-urban regions.
• Price Gap Widens: Prices for new builds (especially condominiums in and near major cities) remain robust, supported by construction cost inflation and persistent demand, while prices for older or secondhand homes are falling or stabilizing.
• Rental Demand Grows: With more elderly households, urban singles, and foreigners seeking flexible living arrangements, rental markets—particularly in well-located suburbs—are strengthening.

For international investors and lifestyle buyers, this means an evolving map: properties that languished on the market in past years now offer rare value, while hot spots demand quick, informed decisions.

2. Data-Driven Analysis: Prices, Supply, and Market Outlook in 2025

• Supply Remains Tight: Although 2025 sees a small increase in new housing supply, construction constraints (labor shortages, high material costs) prevent oversupply. Most new supply still falls short of even tempered demand, especially for condominiums and transport-rich locations.
• Price Growth Slowing, Not Reversing: While the Tokyo Metropolitan Area saw an 8.14% rise in residential property values in early 2025, price increases are now decelerating. Analysts expect steady, modest gains into 2026, as higher mortgage rates and the end of pandemic-era pent-up demand cool the market.
• No Bubble, No Crash: Despite talk of a potential correction, major market watchers see no signs of a sharp downturn in the near future. Demand is supported by urban migration, inbound investment, and Japan’s relatively stable economic outlook.
• Regional Opportunities: With city-center prices out of reach for many, focus is shifting to commuter prefectures (like Gunma and Saitama) where homes are more spacious and affordable, but still offer rapid access to Tokyo and key commercial nodes.

3. Gunma vs. Saitama: A Comparative Look for Foreign Buyers

Gunma is famous for hot springs, beautiful mountains, and serenity, attracting buyers seeking space, tradition, and affordable renovation projects. Properties can be extraordinarily cheap—sometimes under $20,000 USD.

Saitama, as Tokyo’s “bedroom community,” offers quick commutes, reliable infrastructure, and more urban amenities. It’s a favorite with foreign workers, families, and investors looking for steady returns and low vacancy.

Both prefectures are seeing a bump in interest due to work-from-home trends, lifestyle migration, and Japan’s efforts to repopulate underused areas.

4. Financing & Legal Tips: What Foreign Buyers Need to Know in 2025

Ownership Rights

Foreigners can own real estate in Japan outright, with almost no restrictions. Land and buildings are purchased freehold, unlike in many other Asian markets.

Financing Realities

• Mortgage Access: While Japanese nationals and permanent residents receive the best loan rates, some lenders extend mortgages to non-residents or those on long-term visas. However, in 2025, banks are tightening criteria as interest rates edge higher and regulatory scrutiny grows.
• Minimum down payments of 20–40% are typical for foreign buyers.
• Proof of income, Japanese tax ID, and (in some cases) residency are required.
• Yen Advantage: Ongoing yen weakness against the dollar and euro means many foreign buyers find Japanese property cheaper than ever, even after accounting for modestly rising rates.

Legal Process & Taxes

• Transactions are transparent, and due diligence is straightforward for those using trusted agents.
• Expect acquisition taxes (about 3–5% of property value), annual fixed asset taxes, and possible renovation costs for older homes.
• Earthquake-resilience standards are strong; confirm building compliance, especially for pre-1981 structures.

Signing Remotely

Many agencies now offer remote consultations and online completion of contracts, ideal for international buyers.

5. Japan Lifestyle for Expats: The Allure of Gunma and Saitama

Gunma: Nature, Heritage, and Room to Breathe

Wide-open spaces, lush scenery, and iconic hot spring resorts make Gunma a haven for retirees, remote workers, and anyone escaping city crowds. Local communities are increasingly welcoming to newcomers, and many towns offer incentives for akiya renovations.

Saitama: Urban Comfort, Global Connections

Saitama’s larger cities (Omiya, Kawagoe, Urawa) blend suburban comfort with city energy, offering international schools, excellent rail access, and a diverse population. Rental yields are strong in well-located apartments, and Saitama’s growing expat community makes integration easier.

For both prefectures, international buyers can expect a high quality of life, excellent safety and infrastructure, and unique cultural experiences—all within reach of Tokyo’s jobs and attractions.

6. Risks and the Future Outlook

Challenges to Consider

• Demographic headwinds mean some rural areas may see further depopulation, threatening resale values unless local revitalization efforts succeed.
• Slightly higher mortgage rates and stricter lending standards are possible as the Bank of Japan eases out of its ultra-low-rate era.

Opportunities Ahead

• Government and private programs aimed at tackling vacant homes and reviving local communities are gaining momentum.
• With Japan’s economy stabilizing, inbound investment and foreign resident numbers are projected to rise, keeping demand healthy.
• As urban living costs soar, Gunma and Saitama’s combination of affordability and accessibility will remain attractive, especially for buyers seeking lifestyle change or solid long-term value.

Key Takeaways

• Consider strategic investment in Gunma and Saitama for affordability and growth potential.
• Understand local financing and legal processes to secure favorable terms as a foreign buyer.
• Embrace the lifestyle benefits these regions offer, ranging from tranquility in Gunma to urban comfort in Saitama.
