Japan Mortgage Guide 2026: Flat 35, Jutaku Loan, and Sub-1% Rates

Japan possesses one of the most unique mortgage markets in the world, characterized by decades of ultra-low interest rates and the phenomenon of depreciating housing assets. The "Jutaku Loan" is highly accessible for citizens and permanent residents, offering sub-1% rates, but can be exceedingly difficult for temporary residents to secure. This guide explains the 2026 landscape.

Updated 2026-09-11 · Unlike Western markets where the building retains value, in Japan, a wooden house depreciates to essentially zero value over 20 to 25 years for tax and appraisal purposes. The land retains or gains value, but the structure does not. Consequently, buying a home is often viewed as consumption rather than a speculative investment. · Fact-Checked Lending Norms

How Much Can You Borrow in Japan?

Lending in Japan relies less on strict LTV ratios and more on a holistic assessment of your income stability, employment type (Seishain - permanent employee), and health.

Loan-to-Value (LTV) Limits

Citizens and Permanent Residents (PR): Maximum 100% LTV is extremely common. Banks frequently finance the entire purchase price without requiring a down payment (Atamakin), provided your income supports it. You only need cash for closing costs.

Non-Permanent Residents: Maximum 70% to 80% LTV. Getting approved without PR is notoriously difficult and usually requires a 20% to 30% down payment, a spouse who is a Japanese national, or working for a top-tier global corporation.

Debt-to-Income (Hen-sai-Hiritu) Limit

Banks typically cap your total annual debt repayments at 30% to 35% of your gross annual income. For high earners (e.g., above 7 million JPY), this can stretch to 40%.

Crucially, banks calculate affordability using a "stress rate" (Shinsa Kinri), usually around 3.0% to 4.0%, even though actual rates are under 1%.

Use the affordability calculator to test your income against a 3.0% stress rate.

Japanese Mortgage Types

Variable Rate (Hendo Kinri): The overwhelming choice for Japanese buyers (over 70% of new loans) due to rock-bottom rates. Rates adjust semi-annually based on the short-term prime rate. Under the "5-year rule" and "125% rule", payments remain unchanged for 5 years at a time, and when they do adjust, they cannot increase by more than 25%.

Fixed Rate (Kotei Kinri)	Rates are locked for 3, 5, or 10 years, reverting to variable afterwards.

Flat 35: A government-backed mortgage via the Japan Housing Finance Agency (JHF). It offers a 35-year fixed rate. The property must meet strict earthquake and energy efficiency standards to qualify. It is exceptionally popular for freelancers or those lacking PR, as it focuses more on the property's quality than the borrower's employment type.

Current Japanese Mortgage Rates (2026)

Even with the BOJ's slight policy normalization, Japanese rates remain the lowest globally:

Variable Rate (Hendo)	0.35% to 0.55% (with maximum bank discounts)
10-year Fixed	1.10% to 1.40%
Flat 35 (35-year Fixed)	1.80% to 2.10%

*Rates are illustrative averages as of September 2026. Rates depend heavily on the bank's "discount" from the base rate.*

Closing Costs and Taxes

Closing costs in Japan are high, typically requiring 6% to 9% of the property value in cash.

Registration and License Tax (Touroku Menkyo Zei)	Approx. 0.1% to 2.0% depending on the property age and type.

Real Estate Acquisition Tax (Fudosan Shutoku Zei): 3% on land and residential buildings, assessed on the statutory value (which is lower than market value).

Brokerage Fee (Chukai Tesuryo)	Legally capped at 3% of the purchase price + 60,000 JPY + 10% Consumption Tax. This is the largest expense.
Loan Guarantee Fee (Hosho-ryo)	0% to 2% of the loan amount, paid upfront to a guarantee company (or rolled into the interest rate).

Use the budget calculator to estimate your exact cash required to close in Japan.

The Japanese Mortgage Process

1. Save for Closing Costs. Even with a 100% LTV loan, you need ~8% in cash for fees.

2. Jizen Shinsa (Pre-Approval). Takes a few days. Determines your borrowing limit based on your Gensen-choshu-hyo (annual withholding tax slip).

3. Sign the Purchase Agreement (Baibai Keiyaku). You pay an earnest money deposit (Tetsukekin) of 5% to 10% to the seller. If you back out for reasons other than a mortgage denial, you lose this deposit. Ensure a loan contingency clause is included.

4. Hon Shinsa (Final Approval). The bank reviews the specific property, your health check (for life insurance), and issues final approval.

5. Kessai (Settlement). Conducted at the bank with a Judicial Scrivener (Shiho Shoshi). Funds are transferred, and you receive the keys.

What is Group Credit Life Insurance (Danshin)?

Danshin is mandatory life insurance that pays off the entire mortgage if the borrower dies or suffers a severe specified illness. It is usually built directly into the interest rate (e.g., adding 0.2% to the rate) and requires passing a health check. Flat 35 offers Danshin as optional.

Why do Japanese homes depreciate?

Unlike Anglo-American property markets where structural improvements generally appreciate over multi-decade spans, Japan's domestic housing market treats timber residential structures as depreciating assets. Under Japanese statutory tax guidelines, a standard wood-frame home depreciates to residual book value in 20 to 25 years. Land values persist or appreciate based on municipal infrastructure and transit access, but the home itself is culturally viewed as a depreciable consumer good rather than a capital growth vehicle.
