Buying and registering a car in Japan can be a straightforward process if you understand the necessary steps and legal requirements. Whether you're a military personnel looking for a Y-Plate SOFA car, an expat needing an Embassy Blue Plate vehicle, or a resident purchasing a standard Kanji Japanese plate car, this guide will walk you through the essential steps to own and register your vehicle in Japan hassle-free.
Before starting the registration process, decide what type of vehicle suits your needs. In Japan, cars are categorized into different plate types:
Y-Plate SOFA Cars – These are vehicles registered under the Status of Forces Agreement (SOFA) and are specifically for U.S. military personnel.
Embassy Blue Plate Cars – Vehicles used by diplomats or embassy staff.
Kanji Japanese Plate Cars – Standard cars owned by residents and businesses in Japan.
Once you determine your needs, explore car dealerships or online platforms like Direct Cars that specialize in providing SOFA, Embassy, and Kanji plate vehicles.
To purchase a vehicle in Japan, you’ll need to prepare the following documents:
Alien Registration Card or SOFA License (for Y-Plate buyers)
Passport or Resident Card (for Embassy or Kanji plate buyers)
Valid Japanese driver’s license or SOFA permit
Garage certificate (Shakoshomeisho) – Proof that you have a legal parking space
Inkan (Personal Seal) or Signature
JCI (Japanese Compulsory Insurance) Certificate
Shaken (Vehicle Inspection Certificate) for used cars
After selecting your desired car, the dealership or private seller will provide a Bill of Sale (Jidōsha Baikyaku Shōmeisho). If financing is required, dealerships like DirectCars offer assistance in arranging loan options.
A garage certificate is required unless you're buying a 660cc Kei car, which is exempt. To get this:
Visit your local police station with a completed parking space application form.
Provide a lease agreement or proof of ownership of the parking space.
Receive approval (takes about a week).
For SOFA personnel, this step may not be required if living on a military base.
After obtaining the necessary documents, register your car at the nearest Land Transport Bureau (陸運局, Rikuun Kyoku). Steps include:
Submit documents (Bill of Sale, Garage Certificate, Inkan, etc.).
Pay registration taxes and fees, which include:
Weight tax
Automobile tax (based on engine size)
Registration fee
Receive the official license plates for your vehicle.
For Y-Plate and Embassy cars, a different process applies, handled through SOFA offices or embassies.
JCI is mandatory for all vehicles in Japan and is required before the car is legally drivable. It covers third-party liability but does not include comprehensive coverage. Most dealerships assist in arranging JCI for buyers.
While JCI is required, it’s highly recommended to obtain voluntary insurance to cover:
Collision damage
Theft
Natural disasters
Third-party property damage
For used cars or vehicles over 3 years old, a Shaken (車検) inspection is required. This ensures your car meets Japan’s strict safety and emissions standards. Dealerships like DirectCars often sell vehicles with a freshly completed Shaken to simplify the process.
Once your vehicle is registered and insured, you’re ready to hit the road! Keep the following documents in your car at all times:
JCI Certificate
Shaken Certificate (if applicable)
Registration papers
Driver’s license/SOFA permit
Whether you're purchasing a Y-Plate military car, an Embassy Blue Plate vehicle, or a standard Kanji plate car, following these steps ensures a smooth buying and registration process. If you’re looking for a trusted dealership that specializes in all these types of vehicles, Direct Cars provides hassle-free purchases, free delivery around Tokyo and Kanagawa, and assistance with registration and documentation.
