Eligibility, mortgage types, rates, fees, underwriting, lenders, and the application process — how home loans actually work in a higher-rate Japan.
A Japanese mortgage is decided by your income and stability, your credit records, and the property — and the cheapest loan is the one with the lowest all-in cost over your holding period, not the lowest headline rate.
Japan has entered a materially different interest-rate environment from the near-zero years. The Bank of Japan’s operating guideline was around 1.0% after its June 2026 decision, and the average uncollateralized overnight call rate was roughly 0.977% at the end of July 2026. Major lenders have announced or implemented higher short-term prime rates and mortgage reference rates — Mizuho, for example, published that new variable borrowing shown from about 1.025% would rise to 1.275% or more from January 2027. Model the announced future payment, not only today’s teaser.
Underwriting assesses income, employment stability, age, debt, repayment history, household obligations, health for group credit life insurance (団信), the property’s value and legality, and your documentation. A permanent salaried employee with several years of stable Japanese taxable income presents the simplest file; contract, probationary, commission-heavy, self-employed, and company-owner applicants may need more history and be assessed on normalized income.
Check your own credit records at CIC and JICC before applying. Japan has no single public credit score; lenders pull from designated credit-information organizations and apply proprietary rules. CIC records application inquiries for six months and contract/payment data generally through the contract and up to five years after it ends. Avoid repeated applications and new debt in the run-up to a mortgage.
The main product families are the fully fixed Flat 35, variable-rate loans, fixed-period (e.g. 10-year fixed-selection) loans, and mixed-rate loans, plus structures for couples (pair loans, income combination, joint-debtor, parent-child relay). Fixed removes interest-rate risk at a higher initial cost; variable is cheaper now but shifts rate risk to you. Choose variable only if the household survives a 2–3 point stress without selling.
Beyond the rate, the true cost includes a frequently 2.20% origination fee (¥1.10 million on a ¥50 million loan), a guarantee fee (upfront, rate-loaded, or absent), appraisal, registration and license tax, judicial-scrivener fees, group credit life insurance, optional riders, and any early-repayment charge. A nominally lower rate can be the more expensive loan for someone who sells or refinances after a few years.
Preapproval (事前審査) is an initial screening on stated income, debts, identity, employment, and property information — not a promise to lend. Final approval (本審査) is full underwriting after detailed documents and property checks, and it can still fail if documents differ, the appraisal is weak, insurance is unavailable, employment changes, new debt appears, or the property is ineligible. Ask each lender for a dated document showing the execution-month rate, permanent discount margin, LTV and term surcharges, fee schedule, insurance options, required document lists, decision time, validity period, and English support, then compare the internal cost over your expected ownership period.
Fixed-rate mortgage · Japan Housing Finance Agency
A long-term fixed-rate mortgage program backed by the Japan Housing Finance Agency, offered via partner lenders and often accessible without permanent residency.
Fees: Rate and fees vary by lender and loan-to-value — verify current terms.
It is harder but possible. Many banks strongly prefer permanent residency; without it you may face a larger required down payment, a Japanese spouse guarantor, or rejection at some lenders. Flat 35, offered via the Japan Housing Finance Agency, is more rules-based and does not always require PR, making it a common route for non-PR residents. Stable long-term employment and income are decisive. Terms vary widely by bank, so compare several.
There is no universal answer. Floating rates (変動) have been lower and reduce early payments but can rise, increasing your payment later. Fixed rates (固定, including Flat 35) cost more now but lock certainty for the term, protecting you if rates rise. Choose based on how much payment-increase risk you can absorb: if a rate rise would strain your budget, the certainty of fixed can be worth the premium. Model both before deciding.
Compare the all-in cost — execution rate, fees, insurance, and early-repayment costs — over your holding period, not the headline rate.
Preapproval screens stated information; final approval fully underwrites you and the property and can still fail.
