Japan Light Vehicle Tax Calculator

Owning a car in Japan comes with more than just fuel, insurance, and maintenance. One of the biggest costs drivers face every year is the annual vehicle tax (自動車税). This mandatory tax depends on the type of vehicle you drive, its engine displacement, and in some cases, its age.

For many foreign residents and new buyers in Japan, calculating this tax can be confusing. Should you choose a Kei car (軽自動車) to reduce costs, or go for a larger sedan or SUV?

Understanding how the tax system works can help you budget more effectively and avoid surprises. That’s why we created a Vehicle Tax Calculator for Japan 2025 to give you quick, accurate estimates.

With just a few clicks, you’ll know how much you’re expected to pay every year. This tool is based on official tax brackets from the Japanese government, adjusted for the current 2025 rates.

How the annual car tax is calculated in Japan

The annual tax is primarily based on the engine displacement of your vehicle, measured in liters (cc). The larger the engine, the higher the tax. For example:

• A 1.0L car pays significantly less than a 3.0L SUV.
• Kei cars are taxed at a fixed rate regardless of engine size.
• Vehicles older than 13 years receive a surcharge of about 15%.

This system encourages drivers to choose fuel-efficient vehicles and discourages keeping older cars on the road. For many families, it makes Kei cars the most economical choice.

Kei cars: the affordable option

Kei cars (軽自動車) are small vehicles with engines up to 660cc, designed for city use. In 2025, the annual tax for a Kei car is around ¥10,800, making them extremely popular in urban areas like Tokyo and Osaka.

Not only do they save on taxes, but also on insurance, parking permits, and fuel. For students, single workers, or families needing a second car, Kei cars represent a practical and budget-friendly option.

Normal cars and larger vehicles

For regular cars, taxes scale with engine size. For example:

• Up to 1.5L: about ¥34,500
• Around 2.0L: about ¥39,500
• Above 3.5L: ¥58,000 or more
• Luxury cars over 4.5L: ¥76,500+

If your car is over 13 years old, expect the surcharge. That means a 2.0L sedan that normally costs ¥39,500 will jump to ¥45,400.

This is why many owners trade in or upgrade vehicles before the 13-year mark. Dealers and resellers also use this cutoff to price used cars more competitively.
