| Loan Type | Rate Range (Early 2026) |
|---|---|
| Variable rate (variable, 変動金利) | 0.3–0.7% per year |
| Fixed-rate (10-year fixed, 固定10年) | 1.2–1.8% per year |

Types of Mortgage in Japan
1. Variable Rate (変動金利, Hendou Kinri)
The most popular type. The rate is reviewed every 6 months and can rise or fall with the Bank of Japan's policy rate.
Pros:
- Currently the lowest rate option (0.3–0.7%)
- If rates stay low, you pay significantly less in interest
Cons:
- Monthly payments can increase if rates rise
- Long-term unpredictability
Best for: Buyers with sufficient savings to absorb potential rate increases, or those planning to repay early.
2. Fixed-period Rate (固定期間選択型)
The rate is fixed for a set period (3, 5, 10 years), then reverts to the prevailing rate (often variable).
Pros:
- Predictable payments for the fixed period
- Useful if you plan to refinance or repay within the fixed window
Cons:
- Rate resets at the end of the fixed period — often higher
- Partial uncertainty remains
Best for: Those wanting short-term stability but flexibility to reassess later.
3. Flat 35 (全期間固定, フラット35)
The flagship long-term fixed mortgage managed by the Japan Housing Finance Agency (JHHC). The rate is fixed for the full 35-year term.
Pros:
- Complete rate certainty for the life of the loan
- Accessible to foreigners with long-term visas
- Standardized approval criteria (transparent debt-to-income rules)
- No prepayment penalties
Cons:
- Higher initial rate than variable options
- Requires the property to meet JHHC quality standards
Flat 35 eligibility for foreigners:
| Residency Status | Eligible? |
|---|---|
| Permanent resident | ✅ Yes |
| Long-term work visa (5 years+) | ✅ Often eligible |
| Short-term / student visa | ❌ Generally not eligible |
| Non-resident (overseas buyer) | ❌ Not eligible |
Monthly Payment Examples
Based on a ¥40,000,000 (40 million yen) loan:
| Rate | 20-year term | 25-year term | 30-year term | 35-year term |
|---|---|---|---|---|
| 0.5% (variable low) | ¥175,000 | ¥142,000 | ¥120,000 | ¥104,000 |
| 1.0% | ¥184,000 | ¥151,000 | ¥129,000 | ¥113,000 |
| 1.8% (Flat 35 typical) | ¥198,000 | ¥166,000 | ¥144,000 | ¥129,000 |
| 2.0% | ¥202,000 | ¥170,000 | ¥148,000 | ¥132,000 |
Approximate figures using equal installment (元利均等) repayment. Actual figures vary by lender.
Total Interest Cost: Variable vs Flat 35
Over a 35-year loan of ¥40,000,000:
| Rate | Monthly Payment | Total Repaid | Total Interest |
|---|---|---|---|
| 0.5% | ¥104,000 | ¥43.7M | ¥3.7M |
| 1.0% | ¥113,000 | ¥47.4M | ¥7.4M |
| 1.8% | ¥129,000 | ¥54.1M | ¥14.1M |
| 2.0% | ¥132,000 | ¥55.4M | ¥15.4M |
The gap between a 0.5% variable rate and a 1.8% Flat 35 is roughly ¥10–12 million in total interest over 35 years — a significant amount. However, if variable rates rise to 2%+ over the loan term, the total cost could be similar or higher.
How Japanese Mortgage Rates Are Set
Variable Rate Mechanism
Variable mortgage rates in Japan are typically set at prime rate + a spread. As of 2026:
- Short-term prime rate: ~1.625%
- Banks apply discounts — advertised rate often ~0.3–0.7%
The Bank of Japan raised rates slightly in 2024, and there is some expectation of further gradual increases. However, rates remain very low by global standards.
Flat 35 Rate Mechanism
Flat 35 rates are published monthly by the Japan Housing Finance Agency (住宅金融支援機構). They reflect long-term bond market conditions. As of early 2026, the standard Flat 35 rate is around 1.8–2.1%.
Variable vs Fixed: Which Should You Choose?
| Factor | Choose Variable | Choose Fixed (Flat 35) |
|---|---|---|
| Risk tolerance | High (can absorb rate increases) | Low (prefer certainty) |
| Loan term | Shorter (20 years or less) | Longer (30–35 years) |
| Repayment plan | Plan to repay early | Long-term steady repayment |
| Foreign buyer | Less common | More accessible |
| Budget sensitivity | Flexible | Fixed income, tight budget |
A common approach in Japan: borrow at a variable rate with a plan to prepay early if rates rise. However, for foreigners unfamiliar with the Japanese financial system, Flat 35 is often the more accessible and predictable option.
