Introduction: The 2025 Problem and Why It Changes Everything
Japan is entering a new era in real estate, shaped by a profound demographic shift known as the “2025 Problem.” By the end of this year, all members of the country’s first baby boomer generation will be age 75 or older—comprising over 18% of the national population. This milestone isn’t just a population statistic; it is driving deep, irreversible changes to housing demand, property values, and the way investors, buyers, and expats should approach Japanese real estate—especially in regional markets like Gunma and Saitama.
If you’re a foreigner keen on buying property in Japan, searching for investment opportunities, or considering relocation, understanding the implications of the 2025 Problem is essential. This blog explores the latest data and expert insights, focusing on how these trends impact Gunma and Saitama—two prefectures increasingly favored by international buyers.
Background: What is the 2025 Problem and Why Does It Matter?
The “2025 Problem” refers to the demographic reckoning triggered as Japan’s baby boomers (born 1947–49) all become 75+, sharply accelerating the nation’s aging. By 2025, people in this age group will represent over 18% of the Japanese population. This seismic shift brings:
- A surge in elderly households and solo seniors.
- A wave of “inheritance properties” entering the market as older owners pass away.
- Increased pressure on local governments to address property abandonment and depopulation, especially outside core urban zones.
For the real estate market, these demographic forces translate into more vacant homes, changing demand dynamics, and—crucially—new risks and opportunities for foreign buyers, especially in regional areas like Gunma and Saitama.
Data-Driven Analysis: Vacancy, Prices, and the Urban-Rural Divide
Vacant Homes at Record Highs
As seniors age out of home ownership, Japan is witnessing unprecedented property vacancy (akiya), especially in non-metropolitan and rural areas. The trend is most pronounced in towns and smaller cities losing population, but even suburban areas are feeling the effects.
- There is a record-high number of vacant properties in Japan in 2025, with regional areas facing the brunt.
- This increase is due to a combination of inheritance (properties passed on to heirs who may not wish to live there), urban migration, and declining birthrates.
Divergence Between New and Secondhand Home Markets
- Secondhand Homes: Increased supply from elderly owners and inheritance cases has depressed prices for existing/older homes, except in the busiest urban centers.
- New Builds: Prices for new homes and apartments remain high, driven by construction costs, land scarcity in attractive areas, and continued demand in the Tokyo metro region (which includes parts of Saitama).
Market Resilience Where Demand Is Strongest
While Tokyo continues to see strong price growth (+10.7% year-on-year in early 2025), Saitama and other Kanto suburbs are also benefiting from spillover urban demand and commuter appeal. Gunma, while more rural, is seeing stability in prices for good-condition properties and in locations with strong transport links. However, secondary towns and remote areas are more vulnerable to oversupply and price decline because of the aging trend.
Rising Rental Demand
With more seniors downsizing or moving into care facilities, and population mobility increasing post-pandemic, rental demand is rising. This presents new opportunities for investors considering buy-to-let strategies, particularly in neighborhoods popular with families, young professionals, or inbound foreign residents.
Gunma vs Saitama: How the 2025 Problem Plays Out Locally
| Feature | Saitama | Gunma |
|---|---|---|
| Proximity to Tokyo | Immediate neighbor; fast train access to city center | Further out; more rural or semi-urban |
| Vacancy Trends | Some suburban vacancy but strong demand in Tokyo commuter towns | Higher vacancy in rural towns; select areas popular for retreats |
| Price Dynamics | Resilient prices for new builds, moderate drop for old homes | New builds stable; old homes can be deeply discounted |
| Investment Case | Appealing for commuters, families, and investors chasing stable yields | Opportunities for long-term play, akiya renovation, lifestyle buyers |
Saitama draws those who want access to Tokyo jobs and amenities without inner-city prices. Vacancy is highest on the fringes, but prime suburbs see robust demand. New developments and condos near rail hubs remain competitive.
Gunma offers affordability, more space, and lifestyle options (onsen towns, mountain retreats, agriculture). However, buyers must be selective: many remote villages face population decline and high vacancy. Investors can find bargains, but long-term planning and careful area selection are key.
Financing & Legal Tips: What Foreign Buyers Need to Know
Financing: Mortgage for Non-Residents in Japan
- Japanese banks are slowly opening up to foreign buyers, especially if you have resident status, a spouse visa, or a Japanese co-borrower. However, securing a mortgage remains easier for those with permanent residency or stable local employment.
- Some regional banks in Saitama and Gunma are reportedly more receptive to international buyers familiar with the local context, but expect stricter documentation and possible higher down payments.
- Rising interest rates remain a concern for leveraged buyers in 2025, although rates are still low by international standards and increases have been modest.
Legal Considerations
- Foreigners can freely own land and homes in Japan, including in Gunma and Saitama, with some exceptions near sensitive national security zones.
- Inheriting, gifting, or disposing of property can trigger inheritance or capital gains tax—be sure to consult professionals familiar with Japan’s legal framework.
- Many vacant properties (akiya) come with title or maintenance issues, so thorough due diligence is essential, especially when dealing with properties acquired via inheritance or auction.
Property Management
- Managing remote or vacant properties can be a challenge. Foreign buyers have options: property management firms, local caretakers, or creative rental strategies (short-term, long-term, akiya conversion).
- Many local governments now offer incentives to buyers willing to renovate and occupy akiya, including subsidies and tax breaks.
Lifestyle & Living Experience: Real Opportunities, Real Considerations
Why Gunma and Saitama Appeal to Foreigners
- Saitama: Ideal for those who want access to Tokyo jobs, schools, and international communities but at generally lower prices and more residential environments. Infrastructure is well-developed, with shopping, parks, and family-friendly amenities.
- Gunma: Attractive for retirees, digital nomads, or investors interested in rural revitalization, eco-tourism, or the unique culture of Japan’s heartland. The region boasts onsen resorts, hiking, skiing, and a relaxed pace—though language support and international services may be patchier outside urban centers.
Challenges and Solutions
- Language barriers, property maintenance, and integration into local communities remain key challenges. Partnering with trilingual consultants or property managers is crucial.
- The 2025 Problem means more choices but also more due diligence: as property inheritance accelerates, expect a wider gap between “prime” and “problematic” locations.
Risks & Future Outlook: Navigating Change With Confidence
Risks
- Further population decline in rural/aging areas could depress values or make resale difficult.
- Some “bargain” properties may have hidden costs: deferred maintenance, unclear titles, or tax liens.
- Undersupply of new homes in popular areas means buyers should act quickly if targeting prime locations.
Opportunities
- Akiya (vacant homes) initiatives offer unprecedented entry points into Japanese homeownership for foreigners with vision and patience.
- Rising rental demand, especially in well-served suburbs (Saitama) or tourist-favored rural zones (Gunma), can provide steady yield potential.
- Government incentives and local projects are revitalizing select neighborhoods, especially where foreign investment and new residents are sought.
Outlook
Expect modest price appreciation in strong-demand areas, plenty of “value” in older properties (with careful selection), and ongoing support for “foreigners in Saitama” and “Gunma real estate” buyers looking for a unique Japanese lifestyle or smart long-term investment.
