April 29, 2026 in Tokyo, Japan — Owning a car in Japan involves navigating multiple layers of taxation: acquisition tax paid once at purchase, annual weight tax, annual road tax, and the periodic shaken inspection. For a typical family car, first-year ownership costs above the purchase price can exceed ¥150,000. Understanding these costs is essential before buying any vehicle in Japan.
Japan's Vehicle Tax Structure: An Overview
Japan imposes four main categories of vehicle-related taxation:
- Acquisition tax (取得税): One-time tax at purchase, based on vehicle price and engine size
- Weight tax (重量税): Annual tax based on vehicle weight class
- Road tax (自動車税): Annual tax based on engine displacement size
- Shaken inspection (八年式検査): Mandatory periodic inspection with associated fees
These are in addition to parking requirements, compulsory insurance, and fuel taxes already embedded in the price of gasoline.
Acquisition Tax (取得税)
Acquisition tax is paid once at the time of vehicle purchase and is based on the vehicle's assessed value:
| Vehicle Type | Engine Size | Acquisition Tax Rate | ¥2M Car Tax |
|---|---|---|---|
| Regular passenger car | 660cc+ | Up to 3% | ¥60,000 |
| Kei car (mini-car) | 660cc and below | 2% | ¥40,000 |
| Commercial vehicle | All sizes | 3% | ¥60,000 |
| EV (until Mar 2029) | Any | 0% | ¥0 |
For context, the typical new car price in Japan is ¥2,500,000-¥3,500,000, making acquisition tax ¥60,000-¥105,000 for a standard vehicle.
Weight Tax (重量税)
Weight tax is an annual tax levied based on the vehicle's weight category. It is collected when you renew your shaken inspection:
| Weight Category | Annual Weight Tax | 2-Year (Shaken) Amount |
|---|---|---|
| Up to 500kg | ¥500 | ¥1,000 |
| 501-1,000kg | ¥8,200 | ¥16,400 |
| 1,001-1,500kg | ¥16,400 | ¥32,800 |
| 1,501-2,000kg | ¥20,500 | ¥41,000 |
| 2,001-2,500kg | ¥23,600 | ¥47,200 |
| Over 2,500kg | ¥25,200 | ¥50,400 |
Weight tax is typically paid every 2 years at the shaken inspection, so the biennial amount shown above is the amount you pay at each shaken. New cars first pay shaken at 3 years, then every 2 years thereafter.
Annual Road Tax (自動車税)
Road tax is an annual tax based on engine displacement, collected with your vehicle license renewal:
| Engine Displacement | Annual Road Tax |
|---|---|
| 660cc and below (kei) | ¥10,800 |
| 1,001-1,500cc | ¥30,500 |
| 1,501-2,000cc | ¥36,000 |
| 2,001-2,500cc | ¥45,000 |
| 2,501-3,000cc | ¥51,000 |
| 3,001cc and above | ¥58,000 |
A 2.0L (2,000cc) car pays ¥36,000/year in road tax. A kei car (660cc) pays only ¥10,800 — the significant difference incentivises smaller vehicles.
EV Tax Benefits Until March 2029
Japan has extended EV tax benefits to encourage electric vehicle adoption:
- Acquisition tax: 0% (full exemption) until March 31, 2029
- Weight tax: Reduced rate, typically halved for EVs
- Road tax: EV rates are lower, around ¥25,000/year for full EVs
After March 2029, EV tax benefits are expected to be reduced — those planning to buy an EV should do so before the deadline to maximise tax savings.
Shaken Periodic Inspection
Shaken is Japan's mandatory vehicle inspection system. All vehicles must pass shaken inspection:
- New cars: First inspection at 3 years, then every 2 years
- Inspection contents: Safety equipment, emissions, lights, brakes, structure
| Shaken Cost Component | Typical Cost Range |
|---|---|
| Inspection fee (検査料) | ¥30,000-¥50,000 |
| Weight tax (biennial) | ¥16,400-¥41,000 |
| Auto inspection fee (自動車技術審査機構) | ¥1,400-¥2,100 |
| Weight measurement fee | ¥1,800-¥2,500 |
| Total per shaken | ¥50,000-¥100,000+ |
For a typical 1,500kg car at 2-year shaken, total cost is approximately ¥70,000 including inspection fee and weight tax.
Total First-Year Car Ownership Cost Example
| Cost Item | 2.0L Car (¥2.5M) | Kei Car (¥1.2M) | EV (¥4.5M) |
|---|---|---|---|
| Acquisition tax (3%/2%/0%) | ¥75,000 | ¥24,000 | ¥0 |
| First year weight tax | ¥20,500 | ¥8,200 | ¥10,200 |
| Annual road tax | ¥36,000 | ¥10,800 | ¥25,000 |
| First shaken (3yr new) | ¥85,000 | ¥60,000 | ¥75,000 |
| Registration fee | ¥20,000 | ¥15,000 | ¥20,000 |
| Total above purchase price | ¥236,500 | ¥118,000 | ¥130,200 |
Conclusion
Japan's vehicle tax system adds significant first-year costs above the purchase price. A standard 2.0L car priced at ¥2.5M carries approximately ¥236,500 in additional taxes and fees in year one. Kei cars are significantly cheaper to own due to reduced tax rates across all categories. EVs enjoy acquisition tax exemption and reduced weight tax until March 2029 — making now an excellent time to purchase an EV in Japan.
