Introduction
As 2025 approaches, Japan’s real estate market stands on the cusp of significant change. While headlines often sing the praises of Tokyo’s soaring condo prices and growing residential demand, a powerful demographic shift—the aging population—has begun to reshape the landscape of housing demand, supply, and investment strategies across the country. This phenomenon, referred to as the “2025 Problem,” particularly impacts secondary markets like Gunma and Saitama.
For international buyers—whether seeking investment opportunities, lifestyle relocations, or a foothold in Japan’s stable property market—understanding these trends is critical. This article delves into the implications of Japan’s aging society on real estate, providing actionable insights to empower foreign nationals navigating this evolving market.
Background: The “2025 Problem” and Its Impact on Japanese Housing
What is the 2025 Problem?
- By 2025, all members of Japan’s postwar baby boom (born 1947–1949) will reach 75 years of age or older. This age shift will elevate the proportion of Japan’s elderly to over 18% of the population, establishing Japan’s status as a super-aged society source.
- This demographic change will have profound effects on housing demand, especially in rural areas and secondary cities where many elderly homeowners reside.
Key Market Impacts
- Vacancy Rates: With more elderly owners unable to maintain their properties, many homes (known as akiya) are left unoccupied, especially as heirs move to urban areas or abroad source.
- Price Fluctuations: Prices for secondhand homes are stagnating or declining due to reduced demand for older, often less energy-efficient properties. In contrast, new builds in urban settings are seeing a significant uptick in price source.
- Rental Demand: Areas popular with commuters, particularly in Saitama, enjoy robust rental demand, providing stable income prospects for landlords source.
Data-Driven Analysis: Prices, Supply, and Demographic Forces
Price Trends in 2025
- Japan has experienced four years of property price increases, leading to the fastest growth rate seen in over three decades—Tokyo saw a surge of 10.7% year-on-year in mid-2025 source.
- Existing condo prices rose by 7.8% year-on-year as of January 2025, showcasing a robust investment appetite despite emerging construction constraints source.
- As 2025 unfolds, analysts predict a moderation in price growth, attributed to higher mortgage rates and cautious lending practices source.
Supply Trends
- The new housing supply is gradually increasing, hindered by labor shortages and elevated construction costs source.
- Despite a growing number of vacant homes, demand in urban areas continues to drive construction and sales, indicating regional disparities that international buyers should take note of source.
Demographic Patterns
- Migration trends continue to favor urban regions, with Saitama benefiting from young workers and international migrants seeking proximity to Tokyo.
- Gunma is experiencing slower inbound migration, but cities like Takasaki and Maebashi are gaining traction among families and remote workers looking for affordability and lifestyle improvements.
Gunma vs Saitama: Opportunities and Challenges for Overseas Buyers
| Factor | Gunma | Saitama |
|---|---|---|
| Market Type | Regional, semi-rural with growing city centers | Urbanized with strong commuter links to Tokyo |
| Price Trends | Stable to slightly rising in city centers; soft in rural areas | Appreciating, especially for new builds near transport hubs |
| Vacancy Rates | High in rural zones; city centers more resilient | Lower, especially in suburbs close to Tokyo rail links |
| Lifestyle Appeal | Green, affordable, family-friendly, slower pace | Convenient, diverse, pragmatic, with a “Tokyo-adjacent” feel |
| Investment Potential | Higher rental yields in select cities; potential for akiya renovation | Lower yields but with higher stability; easy tenant demand |
| Risk Factors | Liquidity and resale challenges for legacy homes | Higher entry prices and competition for quality properties |
Gunma for Buyers:
- Ideal for those seeking affordable housing and opportunities for renovation in akiya.
- Risks include higher vacancy rates and complex inheritance laws affecting property resale.
Saitama for Buyers:
- Particularly attractive for commuters and families seeking stability mixed with convenience.
- New constructions near key train lines often command high demand, making them a safer investment choice.

Mortgages and Non-Resident Buyers
- Foreign buyers have historically faced challenges securing mortgages, but a growing number of Japanese banks are adapting products to accommodate international investors source.
- Documentation requirements can be extensive, so prospective buyers should prepare for detailed income and tax verification processes.
Legal Considerations

- Zoning regulations may restrict renovations on rural properties. Buyers should also be aware of local tax implications associated with unoccupied homes.
Japan Lifestyle for Expats: Living in Gunma and Saitama
Gunma Experience
- Known for its stunning natural landscapes, Gunma offers a slower-paced lifestyle with cultural traditions and outdoor activities.
