Introduction: Why Saitama and Gunma Are Hotspots in Japan’s 2025 Housing Surge
Japan’s residential real estate market is making headlines in 2025 for record-setting growth not seen since the late 1980s. While Tokyo dominates the conversation with a 10.7% year-on-year price increase, the story is far bigger than the capital. As prices soar and supply remains tight in urban centers, neighboring prefectures like Saitama and Gunma are emerging as prime targets for smart international buyers and investors.
Saitama, long considered a Tokyo suburb, now offers a blend of urban convenience and relative affordability. Gunma, further afield, tempts with spacious homes, scenic beauty, and lower barriers to entry for foreigners. As housing trends shift post-pandemic—families and professionals valuing more space, remote work, and lifestyle upgrades—these two regions stand out as top options.
This blog post explores the key forces behind the 2025 market boom, what’s happening in Saitama and Gunma, the critical considerations for non-Japanese buyers, and why acting now could offer unique opportunities.
Japan’s 2025 Real Estate Market: The Big Picture
Japan’s residential property market is experiencing sustained strength in mid-2025:
- Nationwide, property prices are at their fastest growth pace in 34 years, with no signs of a crash [source].
- Existing condominium prices rose 7.8% year-on-year in January 2025, reaching JPY 819,000 (approx. US$5,439) per square meter [source].
- Price growth is driven by strong urban demand, a delayed supply pipeline, and inflationary pressures on construction and land costs [source] [source].
The Tokyo Metropolitan Area—including Saitama—posted an 8.14% increase in its residential property price index compared to the previous year [source]. Importantly, experts do not see an oversupply risk: new housing supply is increasing only incrementally, with ongoing construction capacity constraints [source]. This supports current valuations and boosts investor confidence.
Market Trends Relevant for Foreign Buyers
- Urban Migration: Urban population growth, driven by lifestyle and career opportunities, continues to funnel demand into Tokyo-adjacent prefectures.
- Remote Work and Lifestyle Shifts: The pandemic has redefined “location,” making spacious homes in Saitama and Gunma more attractive.
- No Bubble, No Crash: Market analysts agree that while the breakneck growth is tapering, a sharp correction is unlikely barring external shocks like a global recession or major rate hikes [source].
Saitama and Gunma: Opportunity Zones for International Buyers
Saitama: Urban Access with a Lifestyle Edge
- Proximity to Tokyo: Many Saitama neighborhoods are 30–40 minutes by train from central Tokyo, making them ideal for commuters and international families.
- Market Dynamics: Rapid price increases are balanced by higher liquidity and continued demand for rentals and resale properties.
- Community and Services: Saitama offers international schools, diverse shopping, green parks, and expanding foreigner-friendly infrastructure.
Gunma: Affordability and Space for a New Generation
- Cost Advantage: Gunma’s property prices remain significantly lower than Tokyo or Saitama, opening options for larger homes, vacation retreats, or investment properties.
- Liveability: With natural attractions, well-developed rail links, and a slower pace, Gunma is winning over remote workers, retirees, and families seeking space and tranquility.
- Growth Potential: As migration from Tokyo accelerates, Gunma is seeing appreciation in select residential areas, particularly near transport nodes.
Data-Driven Analysis: Pricing, Supply, and Investment Returns
| Region | Year-on-Year Price Gain (2025) | Typical Condo Price (per sqm) | Rental Demand | Supply Constraints |
|---|---|---|---|---|
| Tokyo | 10.7% [source] | JPY 819,000 (US$5,439) [source] | High | Severe |
| Saitama | ~8% [source] | Lower than Tokyo, rising | High | Moderate |
| Gunma | ~4–6% (regional avg., est.) | Significantly lower than Saitama | Moderate | Modest, some new stock |
Saitama: Rising prices but still a value play compared to inner Tokyo; popular among renters, which supports investment returns.
Gunma: Slower but steady price gains, appealing for those prioritizing space, land, or long-term lifestyle over short-term profits.
Gunma vs Saitama: Which is Right for You?
| Factor | Saitama | Gunma |
|---|---|---|
| Proximity to Tokyo | 30–40 min by train | 1–1.5 hours by express train |
| Property Prices | Moderate, rising | Lower, still affordable |
| Investment Liquidity | High (quick resale possible) | Moderate (depends on area) |
| Foreign Community | Larger, more amenities | Smaller, but growing |
| Lifestyle | Urban-suburban, well-serviced | Rural-suburban, more space, nature |
| Growth Outlook | Solid, especially for well-located units | Rising in select transport-connected areas |
Financing & Legal Considerations for Non-Japanese Buyers
Changing Mortgage Landscape
- Interest Rates: The Bank of Japan has signaled a gradual move away from ultra-low rates, potentially lifting home loan costs slightly in 2025 [source].
- Availability: Japanese banks are generally cautious but open to foreign buyers with permanent residence or certain income profiles.
- Documentation: Prepare for comprehensive paperwork (proof of income, visa/residence status, Japanese bank account), and expect longer processing times than in some Western markets.
Legal and Regulatory Tips
- Ownership Rights: Foreigners can own land and property in Japan in their own name; no citizenship is required.
- Taxation: You may be subject to property acquisition tax, annual fixed asset tax, and potential capital gains tax on resale. Consult a trilingual expert for planning.
- Due Diligence: Always conduct thorough title checks and property inspections; language barriers and unfamiliar legal nuances make using a bilingual professional critical.
Japan Lifestyle: Living in Saitama or Gunma
- Saitama provides a cosmopolitan feel with international supermarkets, medical facilities, and expat networks. The area is especially popular with young families and professionals who value urban access with slightly less density.
- Gunma appeals to those seeking a slower pace, scenic onsen towns, hiking, and larger homes with gardens. Increasing infrastructure and the possibility of remote work enhance its appeal for relocating foreigners.
- Services & Integration: Both prefectures are investing in community services, multilingual helplines, and programs to help foreigners adjust comfortably.
Risks, Challenges, and Future Outlook
Risks
- Interest Rate Hikes: Any unexpected surge in rates could dampen affordability for both locals and foreigners [source].
- Currency Volatility: Fluctuations in the yen could impact the total cost for international buyers.
- Liquidity in Rural Areas: Gunma’s market is still developing; plan for longer resale periods or focus on high-demand zones.
2025–2026 Outlook
- Moderating Growth: Price increases will likely slow, but the fundamentals remain strong—driven by persistent demand and limited supply [source] [source].
- Migration Trends: As Tokyo’s prices put home ownership out of reach for many, both Saitama and Gunma will see sustained interest from domestic and foreign buyers.

- Gunma is characterized by affordability and space, making it great for families and investors.
