APR and the true cost of a Japanese mortgage
Why headline rates are incomplete: origination fees, insurance, registration, and holding period.
Japanese mortgage ads emphasize the nominal rate and state fees separately, so you must calculate an effective cost from the execution rate, the 2.2% origination or guarantee fee, insurance additions, registration, and your expected holding period.
Key points
- Japan has no single standardized all-in APR display; you build the effective cost yourself.
- A 2.20% origination fee on a ¥50 million loan is ¥1.10 million before other costs.
- A nominally lower rate can be the more expensive loan for a short holding period.
- Include registration, judicial-scrivener fees, insurance, and any early-repayment charge.
Why the headline rate is incomplete
In international usage, APR combines interest and specified fees into one annualized borrowing cost. Japanese mortgage advertising commonly emphasizes the nominal annual rate and states fees separately, rather than presenting one universally comparable all-in APR. The reviewed lender pages, for example, state rates and 2.20% origination fees separately. To compare fairly you must calculate an effective cost using the execution rate, the origination or guarantee fee, insurance additions, registration and license tax, judicial-scrivener fees, and — decisively — your expected holding period.
An all-in cost worksheet
Add up: interest over your expected holding period; the origination fee (often 2.20% — ¥1.10 million on ¥50 million) or a guarantee fee; group credit life insurance and any riders; appraisal; registration and license tax; judicial-scrivener fees; account conditions needed to keep a discount; and any early-repayment charge. Then subtract the opportunity cost of the down payment. Two loans with the same rate can differ by over a million yen once fees are counted, and a low-rate loan with a large fee is a poor fit for a borrower who expects to sell or refinance within a few years.
Key points to carry away: Japan has no single standardized all-in APR display; you build the effective cost yourself; A 2.20% origination fee on a ¥50 million loan is ¥1.10 million before other costs; A nominally lower rate can be the more expensive loan for a short holding period; Include registration, judicial-scrivener fees, insurance, and any early-repayment charge. Use the linked guides and calculators for the full decision, and confirm anything material with the lender, a licensed broker, a judicial scrivener, or a tax accountant before you act.

An annualized all-in borrowing-cost concept. Japanese mortgage comparisons often require calculating it manually from the rate plus fees.
How do I find the cheapest mortgage?
Compare the all-in cost — execution rate, fees, insurance, and early-repayment costs — over your holding period, not the headline rate.
What is the total cost of borrowing?
Interest plus origination or guarantee fees, insurance, registration, appraisal, account conditions, and early-repayment costs over your holding period.
