Exporting a used car from Japan as a resident: costs, paperwork and risks

To export used car Japan paperwork starts with the owner: you first file export deregistration (輸出抹消仮登録, yushutsu massho kari-toroku) at your transport branch office (運輸支局). You can apply once the export date is decided, up to 6 months before it. The fee is 500 yen (from April 2026). You need an owner’s seal certificate (印鑑証明書), so register a seal at the city office first. All as of October 2026.

Two situations, not one

• You sell your car to a buyer who will export it. This is the common case when leaving Japan. The buyer or dealer handles deregistration and customs. Your risks are on the selling side, covered below. For the sale itself, see selling or scrapping your car.
• You export your own car to your home country or next posting. This is the procedure below.

What is export deregistration?

It is the registration step for sending a car overseas. A car stays registered in Japan until you do it. It does not apply to large special vehicles or towed vehicles. Once the car is deregistered for export, the certificate you receive is what customs looks at.

If you cancel the export, or the planned export date passes, you must return the certificate to the office (500 yen at the window).

What does a foreign owner need?

The seal is the foreigner snag. The seal certificate comes from your city office and needs a registered seal. Foreign residents can register one; see hanko for foreigners. If you moved since the car was registered and the address on the 車検証 differs, the office wants documents proving the move, so also read car registration and transfer in Japan.

If the owner on the 車検証 is not you, ask the transport office what they need.

The steps

Customs: why you cannot just carry it

Since July 2005, customs checks the 輸出抹消仮登録証明書 when reviewing an export declaration for a used car. Also since 2005, cars (including motorcycles and mopeds) are excluded from traveler’s-baggage customs (旅具通関) and handled only through business customs clearance (業務通関). In practice that means you work with a shipping agent or a customs broker.

Customs uses police stolen-vehicle data and the registration data to examine used-car exports, and large X-ray equipment on containers. This is aimed at stolen cars. A legitimate export with the certificate in hand is the normal case.

Taxes and what comes back

Ask a 税理士 about your own case.

Fraud and selling risks

The consumer center reports these complaints about selling used cars:

• a forced contract at the appraisal, with the buyer reluctant to leave
• high cancellation fees
• price cuts after the contract, such as for “engine noise” or accident history

Its advice: do not sign at the appraisal, read the cancellation clause in advance, and if you told them about accident history beforehand you need not accept later reductions for it. Car sales to dealers have no cooling-off (they fall outside the Specified Commercial Transactions Act). Complaints about used cars numbered 8,642 in FY2025.

Also:

• Make sure the car is actually deregistered or transferred. If the buyer does not transfer registration, Tokyo’s tax bureau says the seller keeps getting billed for car tax. Ask the transport office or your buyer for proof.
• Expect an ID check. Secondhand dealers must verify your identity for purchases of 10,000 yen or more, and for motorcycles at any price.
• For disputes, call the Consumer Hotline 188, or the JPUC car-selling helpline (0120-93-4595).

If you are leaving Japan

Work backwards from your departure date. See the leaving Japan checklist. Start the seal registration early, because the seal certificate must be less than 3 months old when you file.
