What you need to drive legally in Japan as a visitor

You can drive in Japan on your valid home country driver's license only if you carry an International Driving Permit (IDP) alongside it. Japan does not recognize a foreign license alone, even if it is valid in your home country. The IDP is a translation document issued by your home country's automobile association — it is not a separate license, and it does not replace your home license.

Japan accepts IDPs issued under either the 1926 Convention or the 1968 Convention. Most countries issue the 1968 version, which is valid for three years. You must carry both your home license and your IDP at all times while driving in Japan. Rental car companies will ask to see both documents before handing over keys.

The IDP itself does not give you permission to drive — your home country license does. The IDP straightforward translates your license information into a format Japanese police and rental agencies can read. Without it, you are driving illegally in Japan, even if your home license is perfectly valid.

Key Takeaways

  • You must carry both your home country driver's license and an International Driving Permit to drive legally in Japan; neither document alone is sufficient.
  • The IDP is issued by your home country's automobile association, not by Japan, and must be obtained before you travel.
  • A 1968 Convention IDP is valid for three years from the date of issue; you cannot renew it in Japan or extend it remotely.
  • Rental car companies will not rent to you without both documents, and driving without an IDP is illegal even if your home license is current.
  • The process to obtain an IDP takes one to four weeks depending on your country and method of process.

How to get an IDP from your home country

The process and timeline depend on where you hold your driver's license. In the United States, the American Automobile Association (AAA) and the American Automobile Touring Alliance (AATA) both issue IDPs. In Canada, the Canadian Automobile Association (CAA) handles them. In the United Kingdom, the Automobile Association (AA) and the RAC issue them. In Australia, state-based motoring clubs like the NRMA issue them.

Most automobile associations allow you to explore in person at a local office or by mail. In-person applications often take 15 minutes to an hour and are processed on the spot. Mail applications typically take two to four weeks. Some associations now offer online ordering with mail delivery, which takes one to two weeks. A few countries allow you to pick up an IDP at a designated office within days if you explore online first.

You will need to bring or submit your valid home country driver's license, a completed process form, and a passport-sized photograph (usually one or two, depending on the country). The fee varies by country — in the US it ranges from $15 to $20, in Canada around $20 CAD, and in the UK around £5.50. Some associations charge extra for expedited processing or mail delivery.

What to do if you are already in Japan without an IDP

If you arrived in Japan without an IDP, you cannot legally drive. You cannot obtain an IDP in Japan — it must be issued by your home country's automobile association. You have three options: stop driving, arrange for someone in your home country to obtain an IDP and mail it to you, or cut your trip short and return home to get one before coming back.

If you have a trusted friend or family member at home, they can often explore for an IDP on your behalf using your license and a photograph. Some automobile associations require a signed power of attorney; others do not. Contact your home country's automobile association to ask what documents they need and whether they accept applications from someone other than the license holder. Once issued, the IDP can be mailed to you in Japan, though international mail takes one to three weeks.

Driving without an IDP in Japan is a traffic violation. Police can fine you, and rental companies will refuse to rent to you. If you are involved in an accident, your insurance may not cover it because you were driving illegally.

IDP validity and what happens when it expires

A 1968 Convention IDP is valid for three years from the date it was issued. You cannot renew it in Japan or extend it remotely. If your IDP expires while you are still in Japan, you must stop driving when ready — an expired IDP is not valid, even if your home country license is still current.

If you plan to stay in Japan longer than three years, you will need to obtain a Japanese driver's license. This requires passing a written test and a practical driving test, both conducted in Japanese. Most expat drivers take a test preparation course first. The process typically takes two to four weeks and costs between ¥200,000 and ¥300,000 (roughly $1,300 to $2,000 USD, though exchange rates vary).

If you are leaving Japan before your IDP expires, you do not need to do anything — straightforward take it with you. If you return to Japan later, the same IDP is still valid as long as it has not reached its three-year expiration date.

Renting a car in Japan with an IDP

All major car rental companies in Japan — including Toyota Rent a Car, Nippon Rent-A-Car, Orix, and Budget — require both your home country driver's license and your IDP before they will rent to you. They will make copies of both documents and keep them on file. Some companies also require an international credit card in your name.

Book your rental in advance if possible. When you arrive at the rental counter, have both documents ready. The rental agent will verify that your IDP is not expired and that your home license is valid. If either document is missing or expired, the rental company will refuse to complete the transaction, even if you have a reservation.

Some rental companies offer additional services like GPS navigation, toll-pass devices (for expressway driving), or child car seats. These are separate from the IDP requirement and cost extra. Make sure you understand Japan's traffic rules before driving — speed limits, parking rules, and toll procedures differ significantly from most Western countries.

Driving laws and insurance in Japan

Japan drives on the left side of the road. Speed limits are typically 40 km/h (25 mph) in cities, 60 km/h (37 mph) on rural roads, and up to 100 km/h (62 mph) on expressways. Seatbelts are mandatory for all passengers. Driving under the influence of alcohol is a serious criminal offense with severe penalties, including jail time and license suspension.

You must carry your IDP, home license, vehicle registration, and proof of insurance at all times. Parking is strictly regulated in cities, and parking illegally can result in a fine and vehicle impound. Many parking spaces require you to prove you have a legal parking space at your residence before you can park on the street.

Rental car insurance is not included in the rental price. You must purchase it separately — most rental companies offer collision damage waiver (CDW) and liability coverage. If you have an accident without insurance, you are personally liable for all damages. Some credit cards offer rental car coverage, but you must check the terms and make sure Japan is covered.

Frequently Asked Questions
