Japanese home loan rates — the cheapest in the developed world
Thanks to decades of BoJ accommodative policy, Japanese mortgage rates are remarkably low. Variable rates at major banks (Mizuho, SMBC, MUFG, SBI Net Bank, Rakuten Bank) sit between 0.3% and 0.6% in 2026. Fixed rates via Flat 35 (the government-backed JHF product) range 1.7-2.0% for 21-35 year terms. A common compromise is the 10-year fixed-then-floating mix loan at ~1.0-1.3%.
35-year terms (and now 40)
Standard Japanese mortgages run 35 years — longer than most countries. Some banks now offer 40-year loans for buyers under 40. The binding constraint is borrower age at final payment (typically capped at 80). A ¥50M loan at 0.5% variable over 35 years = ~¥130,000/month.
Foreigners & mortgage eligibility
Permanent Residency (eijūken) is the fast path. Without PR, banks like SMBC Trust/Prestia, Shinsei Bank, and SBI Shinsei will lend to long-term residents with 3+ years tenure, stable income, and typically a 20% deposit. A Japanese spouse also unlocks most major banks. Expect more scrutiny on employer and visa status than on raw income.
Jūtaku loan tax credit
The housing loan tax credit returns up to 0.7% of your outstanding loan balance as a direct tax credit each year for 13 years (subject to energy-efficiency grade and home-type caps of ¥210k-¥350k/yr). Over the credit period, this saves most buyers ¥3-5M — effectively making the already-cheap loan even cheaper.
Frequently Asked Questions
Everything you need to know, in one place.
What are Japanese mortgage rates in 2026?
Variable rates: 0.3-0.6% at major banks (Mizuho, SMBC, MUFG, SBI Net Bank). Fixed rates via Flat 35 (JHF-backed): 1.7-2.0% for 21-35yr. Mix loans (10yr fixed then floating): ~1.0-1.3%. Among the lowest in the developed world thanks to BoJ policy — but expect tighter criteria for foreigners without permanent residency.
How long are Japanese mortgages?
Standard is 35 years (longer than most countries). Some banks now offer 40-year loans for younger buyers. Borrower age + loan term typically cannot exceed 80 at final payment. 35-year term on a ¥50M loan at 0.5% variable = ~¥130,000/month.
Can foreigners get a mortgage in Japan?
Yes, but typically need Permanent Residency (eijūken) or a Japanese spouse. Some banks (SMBC Trust/Prestia, Shinsei, SBI Shinsei) lend to non-PR holders with 3+ years tenure and stable income. Expect 20% deposit and a Japanese guarantor in many cases.
What is the housing loan tax credit (jūtaku loan kōjo)?
Up to 0.7% of your outstanding loan balance (max ¥210k-¥350k/year depending on home type) as a direct tax credit for 13 years. Applies to homes meeting energy-efficiency standards, primary residence, loan ≥10 years. Saves ~¥3-5M over the credit period for most buyers.
What extra costs should I budget for?
Shotokuzei + fudōsan shutokuzei (acquisition tax ~3-4%), registration tax (0.1-0.4%), stamp tax, judicial scrivener fees, agent commission (3% + ¥60k + tax), loan guarantee fees (~2% of loan), and fire insurance. Budget 7-10% above sticker price.
Variable vs fixed — which is safer in Japan?
With BoJ gradually tightening in 2024-2026, variable rates (0.3%-0.6%) may slowly climb. Most Japanese borrowers still pick variable due to the large rate gap vs 10y fixed (1.0%-1.3%) or Flat 35 (1.7%-2.0%). "125% rule" caps monthly payment increases at 25% every 5 years on most variable loans — limits shock but negative amortization can accumulate. Fix if: you bought near maximum borrowing capacity, plan to hold 20+ years, prioritise budgeting certainty. Variable if: large cushion in income and offset against a shorter effective term.
