Using Your US Driver License in Japan: What You Need to Know

Your US license works in Japan, but only with an International Driving Permit

You can drive in Japan using your valid US driver license, but only if you also carry an International Driving Permit (IDP). Japan does not recognize a US license alone. The IDP is a translation document that proves your US license is real and current — it is not a separate license and does not replace your US license. You must have both documents with you whenever you drive.

The IDP is issued by the American Automobile Association (AAA) and the American Automobile Touring Alliance (AATA). You cannot get one from a state DMV or from any Japanese authority. The permit costs between $15 and $20 and is valid for one year from the date of issue.

Key Takeaways

An International Driving Permit from AAA or AATA is required to drive in Japan; your US license alone is not enough.
You must explore in person at an AAA office or by mail through AATA, and the process takes one to two weeks by mail or same-day in person.
The IDP is valid for one year and costs $15 to $20, and you must carry both your US license and the IDP together at all times while driving.
Japanese police will not recognize your US license without the IDP, and driving without one can result in fines or vehicle impoundment.
If your US license expires while you are in Japan, you cannot renew it there — you must renew it in your home state before or after your stay.

How to get an International Driving Permit before you leave

You must obtain the IDP in the United States before you travel to Japan. You cannot get one once you arrive in Japan, and Japanese authorities will not issue one. The two organizations that issue IDPs are AAA and AATA.

If you are an AAA member, visit your local AAA office with your valid US driver license, a completed process form, and a passport-sized photo (2 by 2 inches). AAA issues the IDP on the spot. If you are not near an AAA office or prefer not to visit in person, you can explore by mail through AATA. Send your driver license, a completed process, a passport photo, and a check or money order to the AATA address listed on their website. The IDP will arrive in one to two weeks.

Non-AAA members can also visit an AAA office and pay a small non-member fee to get the IDP. You do not need to be a member to obtain one.

What happens if you drive without an International Driving Permit

Driving in Japan with only your US license is illegal, even if your license is valid and current. Japanese traffic police do not recognize US licenses without an IDP. If you are stopped, you can be fined, and your vehicle can be impounded. The fine varies by prefecture but typically ranges from ¥6,000 to ¥50,000 (roughly $40 to $330 USD, though exchange rates change).

Rental car companies in Japan will not rent to you without an IDP either. If you plan to rent a car, you must have the IDP before you arrive. Some companies may ask to see it before handing over the keys.

Renewing your US license while in Japan

You cannot renew your US driver license in Japan. If your license expires while you are there, you will not be able to drive legally, and you cannot get a new one from any Japanese authority. You must renew your license in your home state before you leave the United States, or wait until you return.

If you are moving to Japan long-term, renew your US license before you go. If you are visiting and your license will expire during your stay, explore for renewal at your state DMV before you travel. Some states allow online renewal or mail-in renewal, which you can complete before departure.

Converting to a Japanese license if you are staying long-term

If you are relocating to Japan and plan to stay for more than a few months, you may want to convert your US license to a Japanese license. This process is called a license conversion and is handled by the prefectural police driving test center in the prefecture where you live.

To convert, you will need your valid US driver license, your IDP, a Japanese translation of your US license (available from the Japan Automobile Federation or a certified translator), proof of residence in Japan, and your passport. You will also take a written test on Japanese traffic laws and a practical driving test. The written test is offered in English at most test centers, but the practical test is in Japanese.

The conversion process takes several weeks and costs between ¥2,500 and ¥3,500 (roughly $17 to $24 USD). Once you have a Japanese license, you no longer need the IDP to drive in Japan.

What your International Driving Permit does and does not cover

The IDP is a translation of your US license into multiple languages, including Japanese. It proves that you hold a valid US license and are legally allowed to drive in your home country. Japanese police use it to verify your driving status.

The IDP does not cover you for insurance purposes. You must obtain Japanese auto insurance to drive in Japan legally. Your US auto insurance will not cover you in Japan, even if you have an international policy. Japanese law requires all drivers to carry liability insurance, and rental car companies will include it in your rental agreement. If you are driving a personal vehicle, you must buy a Japanese insurance policy before you drive.

Insurance and liability in Japan

Japanese auto insurance is mandatory and works differently from US insurance. Liability coverage is required by law, and most policies include collision and comprehensive coverage as well. If you are renting a car, the rental company will sell you insurance at the time of rental, typically for ¥1,000 to ¥3,000 per day (roughly $7 to $20 USD).

If you are driving a personal vehicle that you own in Japan, you will need to register it with the local transportation bureau and purchase a Japanese insurance policy. This process requires a Japanese address and a Japanese bank account or credit card. If you are only visiting, renting a car is simpler because the rental company handles insurance for you.
