Car Loan Calculator — Japan
Estimate your monthly car-loan installment in JPY using Japan's typical auto-finance rates, and see the full interest cost. No signup, no account needed.
Enter a car price, a down payment of 0–90%, a rate between 0% and 100%, and a term above zero (up to 50 years) to see results.
Car finance rates in Japan (2026)
Car loans in Japan typically run about 1.5–4.5% p.a. (bank loans 1.5–3%, dealer 1.9–4.5%). Bank loans are usually cheaper than dealer financing.
These are reference figures for 2026 - always confirm the current rate and the effective (reducing-balance) APR with the lender before you commit.
Where to get a car loan in Japan
Commonly used providers include Toyota Financial Services, Nissan Financial, Rakuten Bank and Orix Auto Leasing. Rates and terms vary by lender, your credit profile, and whether you are buying new or used - it pays to compare at least two or three offers.
Deposit and loan term
Deposit requirements vary by lender. Loan terms run up to about 7 years. A bigger deposit and a shorter term both cut the total interest you pay - use the calculator above to see the trade-off for your own numbers.
Worked example
For every ￥4,000,000 financed at 3.45% over 5 years:
- Monthly installment: ￥72,677
- Total repaid: ￥4,360,647
- Total interest: ￥360,647
Scale to your financed amount, and remember a bigger deposit and shorter term lower the total interest.
How to pay less interest on your car loan
- Put down a larger deposit - it reduces both the monthly payment and the total interest.
- Pick the shortest term you can comfortably afford; a longer term lowers the monthly cost but raises the total.
- Compare the effective reducing-balance rate, not a headline flat rate - a flat rate looks cheaper than it really is.
- A stronger credit profile usually earns a lower rate, so it is worth checking before you apply.
A named-lender rate check: SMBC's マイカーローン (2026)
Sumitomo Mitsui Banking Corporation (SMBC), one of Japan's three megabanks, published a variable マイカーローン (My Car Loan) rate of 3.450% per year as of 2 September 2026. Regional banks price similarly but with a wider spread — San-in Godo Bank's car loan ranged 2.05%–4.55% as of 3 August 2026, depending on the applicant's profile and loan term.
Across the wider market, online banks and dealer financing companies publish their own rates (check on each lender's own site), while dealer financing (tied to a specific new car) sometimes comes with manufacturer-subsidized 0% campaigns on select models. This calculator defaults to 3.45% as a realistic bank-loan reference; always confirm the current sheet with your lender before applying.
A more realistic example: financing a ¥3,000,000 used car at 3.45% over 5 years works out to about ¥54,500/month, with total interest of roughly ¥270,000 over the life of the loan.
The legal ceiling on interest: Japan's Interest Rate Restriction Act
Japan does not leave car loan pricing to the market alone. The Interest Rate Restriction Act (利息制限法) sets a hard statutory ceiling on annual interest depending on the size of the loan principal: 20% for loans under ¥100,000, 18% for ¥100,000 up to ¥1,000,000, and 15% for ¥1,000,000 or more. Any interest charged above these thresholds is void for the excess, whatever the contract says.
For context, almost every car loan in Japan — whether a megabank's variable-rate マイカーローン, a regional bank's product, or dealer financing — is priced in the low single digits (roughly 1.5%–4.5% p.a., see the SMBC and San-in Godo Bank figures above), which sits far inside the 15% ceiling that applies to loans of ¥1,000,000 or more (the typical size of a used-car loan) and even further inside the 18%–20% ceilings that would apply to a smaller loan. In practice the statutory cap matters more for unsecured personal loans and credit-card cashing than for car financing, but it is a useful reference point: if you are ever offered car financing priced anywhere near double digits in Japan, that alone is a signal to check the lender and contract carefully.
What owning the car costs after the loan is repaid
A Japanese car loan's monthly instalment is only part of the running cost. Every registered car also owes an annual automobile tax (自動車税), billed each May 31 for the tax year running from the previous April 1, and scaled to engine displacement for cars first registered from October 2019 onward: ¥25,000 up to 1,000cc, ¥30,500 for 1,001–1,500cc, ¥36,000 for 1,501–2,000cc (the range most ordinary passenger cars fall into), ¥43,500 for 2,001–2,500cc, rising to ¥110,000 above 6,000cc.
On top of that, a separate weight tax (自動車重量税) is paid at first registration and again at every shaken (vehicle inspection) renewal, charged per 0.5 tonnes of vehicle weight per year of the inspection cycle: ¥2,500 per 0.5t/year for cars that meet current fuel-efficiency standards ("eco-cars"), versus ¥4,100 per 0.5t/year for cars that do not. Finally, compulsory third-party insurance (jibaiseki hoken, 自賺責保険) must be renewed alongside shaken; the 24-month premium for a standard passenger car is ¥17,650 for policies starting before 1 November 2026, rising to ¥18,560 from that date — the first change to this compulsory-insurance rate in 13 years. Budgeting a Japanese car purchase means adding these recurring taxes and mandatory insurance on top of whatever the loan calculator above shows for the financed amount. As a rough illustration, a 1,500–2,000cc car already on the road faces roughly ¥36,000 in automobile tax, plus weight tax and a share of the 24-month compulsory-insurance premium each shaken cycle — several tens of thousands of yen a year that a loan quote alone will not reveal, and that is before optional comprehensive insurance, which the law does not mandate but which almost every lender and dealer will strongly encourage for a financed vehicle.
Frequently Asked Questions
What is the typical car loan rate in Japan?
As a 2026 reference, car finance in Japan runs about 1.5–4.5% p.a. (bank loans 1.5–3%, dealer 1.9–4.5%). Your actual rate depends on the lender, your credit profile, and whether the car is new or used.
How much deposit do I need for a car loan in Japan?
Deposit requirements vary by lender. A larger deposit lowers both your monthly payment and the total interest you pay.
Which lenders offer car loans in Japan?
Commonly used providers include Toyota Financial Services, Nissan Financial, Rakuten Bank and Orix Auto Leasing. It pays to compare two or three offers, since rates and terms vary by lender and by your credit profile.
How is the car loan installment calculated?
Using the reducing-balance formula P × r × (1+r)ⁿ ÷ ((1+r)ⁿ − 1) on the financed amount. Dealers may quote a lower-looking flat rate; convert to the effective rate to compare.
What car loan rate does SMBC currently offer?
Sumitomo Mitsui Banking Corporation's variable-rate マイカーローン (My Car Loan) stood at 3.450% per year as of 2 September 2026, per the bank's own published rate table. Rates at other megabanks and regional banks vary, so it's worth checking the current sheet before applying.
Bank loan or dealer financing — which is cheaper in Japan?
Bank loans are usually cheaper on the headline rate (SMBC published 3.450% and San-in Godo Bank 2.05%–4.55%; check dealer finance rates on the finance company's own site), but dealer financing occasionally beats that with manufacturer-subsidized 0% campaigns tied to a specific new model — worth comparing both before you decide.
Are Japanese car loan rates rising with the Bank of Japan's policy rate?
Yes — variable-rate bank car loans have been drifting upward through 2024–2026 as the Bank of Japan has moved its policy rate off zero, though the increases have been gradual rather than sharp.
What is the maximum interest rate a lender can legally charge on a car loan in Japan?
Japan's Interest Rate Restriction Act caps annual interest at 20% for loans under ¥100,000, 18% for ¥100,000–¥1,000,000, and 15% for loans of ¥1,000,000 or more; interest above these limits is void. Actual car loan rates (roughly 1.5%–4.5% p.a.) sit far below any of these ceilings.
Besides the loan payment, what does a car cost to keep on the road each year in Japan?
Expect an annual automobile tax of ¥25,000–¥43,500 depending on engine size (most ordinary cars owe ¥36,000), a weight tax of ¥2,500–¥4,100 per 0.5 tonnes per year paid at each shaken inspection, and compulsory third-party insurance renewed with shaken (¥17,650 for 24 months, rising to ¥18,560 from 1 November 2026). None of these are included in the loan repayment itself.
