Car Tax Calculator

Japanese automobile tax is a local tax generally charged to the vehicle owner as of April 1. Amounts are based mainly on engine displacement brackets. This tool estimates the annual automobile tax amount for private passenger cars by combining the base bracket, age-related surcharge, and green tax incentive settings.

What This Estimate Includes and Excludes

This page focuses on an estimate of annual automobile tax and kei car tax. It does not include automobile weight tax, environmental performance tax, inspection fees, compulsory automobile liability insurance, voluntary insurance, or local administrative differences. For actual payment, follow the tax notice from your prefecture or municipality, vehicle inspection documents, and official guidance.

When comparing yearly car ownership costs, look beyond tax alone: fuel, parking, insurance, inspection, and loan costs can matter just as much.
