Car Ownership Costs in Japan: Taxes, Insurance, Maintenance

Owning a car in Japan involves far more than the purchase price. Drivers must budget for car tax (自動車税), shaken inspection (車検), mandatory insurance (自動車保険), financing, and yearly maintenance (自動車維持費).

Many underestimate the real car ownership cost in Japan (日本の自動車維持費). Kei cars (軽自動車), standard sedans (普通車), and imported vehicles all bring different expenses. Taxes, insurance, and inspections quickly add up every year.

With our calculators, you can estimate vehicle tax (自動車税) in Japan, shaken inspection fees (車検費用), and annual maintenance costs (自動車維持費用). These tools help drivers plan clearly, compare car insurance (自動車保険)quotes, and prepare for personal or commercial vehicle use.

Vehicle Tax in Japan (自動車税)

Annual vehicle tax (自動車税) depends on engine displacement, type, and vehicle age. Kei cars (軽自動車) pay around ¥10,800 yearly, while larger sedans and SUVs can exceed ¥50,000. This system encourages drivers to choose eco-friendly and fuel-efficient vehicles.

Cars older than 13 years face additional surcharges. Japanese authorities apply higher automobile tax (自動車税増税)for older cars, pushing owners toward newer, environmentally friendly models. This policy reduces pollution and ensures road safety, but it increases costs for drivers who keep cars long-term.

Our tax calculator instantly estimates yearly payments based on engine size, age, and usage, providing accurate numbers instead of vague averages.

Shaken Inspection and Mandatory Costs (車検と自賠責保険)

The shaken inspection (車検) is mandatory in Japan. Conducted every two years, it checks safety, emissions, and overall compliance with regulations. Depending on the car type, shaken fees (車検費用) can reach ¥40,000–¥100,000 annually when averaged.

Alongside shaken, drivers must pay compulsory auto insurance Jibaiseki (自賠責保険). This coverage is required by law and protects against injury liability. In addition, most drivers purchase voluntary insurance (任意保険) to cover accidents, damage, and theft.

Combining shaken (車検), insurance (自動車保険), and taxes (自動車税) provides the true picture of car ownership costs in Japan.

Annual Maintenance Expenses (自動車維持費)

Beyond taxes and inspections, drivers face yearly maintenance expenses (維持費). These include oil changes, tires, brakes, and unexpected repairs. On average, Japanese households spend ¥200,000–¥500,000 per year on maintenance, depending on mileage and vehicle type.

Kei cars (軽自動車) are cheaper to maintain, but imported cars and luxury sedans often require higher repair and service costs. Shaken inspections also reveal repairs that may increase yearly expenses significantly.

Our maintenance calculator estimates costs based on mileage, car age, and region. It includes shaken, insurance, and taxes, giving drivers a complete financial overview.
