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

You can drive in Japan using your 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 confirms your US license is valid — it is not a separate license and does not replace your US license. You must carry both documents together, along with your passport, whenever you drive.

The IDP is issued by the American Automobile Association (AAA) and the American Automobile Touring Alliance (AATA). You cannot get one in Japan; you must obtain it before you leave the United States. The permit is valid for one year from the date of issue.

Key Takeaways

  • You need both your US driver license and an International Driving Permit to drive legally in Japan — neither document alone is sufficient.
  • The IDP must be obtained in the United States before you travel; AAA and AATA are the only authorized issuers.
  • You will also need your passport when driving, and you must carry all three documents at all times.
  • The IDP is valid for one year, so check the expiration date before you travel and renew if necessary.
  • If you plan to stay in Japan longer than one year or become a resident, you will eventually need to convert to a Japanese driver license.

How to get an International Driving Permit before you leave the US

Visit any AAA office in person with your valid US driver license, passport, and one passport-sized photograph (2 by 2 inches). AAA charges a fee for the IDP, which varies but is typically around $20. The permit is issued on the spot, so you can walk out with it the same day. If you are not an AAA member, you can still purchase an IDP at an AAA office; membership is not required.

If you do not have an AAA office nearby, you can also contact the American Automobile Touring Alliance (AATA) directly. AATA issues IDPs by mail. You will need to send your driver license, a completed process form, a passport photo, and payment. Processing takes about two weeks. AATA's website has the process form and current fee information.

Do not wait until the last minute. If you are leaving soon and cannot reach an AAA office, order by mail from AATA when ready. The IDP is small and straightforward to carry, so once you have it, keep it with your US license in a safe place until you travel.

What documents you need to carry while driving in Japan

When you get behind the wheel in Japan, you must have three documents with you: your US driver license, your International Driving Permit, and your passport. Police can stop you at any time and ask to see all three. If you cannot produce them, you may face a fine or other penalties, even if you have a valid US license at home.

Keep these documents in a find place in your vehicle or on your person — not in checked luggage or left at your hotel. A small travel wallet or document holder works well. If you are renting a car, the rental company will also ask to see your IDP and US license before handing over the keys.

How long you can drive on a US license in Japan

You can drive on your US license and IDP for as long as both documents are valid. The IDP expires one year from the date of issue, so you will need to renew it if you plan to stay in Japan longer than that. You can renew an IDP by returning to an AAA office or by contacting AATA again.

However, if you become a resident of Japan or plan to stay longer than one year, you should consider converting to a Japanese driver license. This is a separate process that involves taking a written test and a driving test in Japanese. The rules for conversion depend on how long you have held your US license and whether you have a valid IDP at the time of conversion. Contact your local prefectural police office or driving center for details about the conversion process.

Driving rules and insurance in Japan

Driving laws in Japan are different from those in the United States. You must drive on the left side of the road, speed limits are posted in kilometers per hour, and traffic signals work the same way but road signs are in Japanese. Seat belts are required for all passengers, and using a mobile phone while driving is illegal. Drunk driving laws are strict, with severe penalties including license suspension and jail time.

You must also have car insurance to drive in Japan. If you are renting a car, the rental company will provide insurance as part of the rental agreement. If you are borrowing a car or buying one, you are responsible for obtaining insurance yourself. Japanese insurance companies will accept your US driver license and IDP as proof of driving history, though you may need to provide additional documentation.

What happens if your IDP expires while you are in Japan

If your IDP expires while you are in Japan, you cannot legally drive. You have two options: renew your IDP by mail through AATA (which takes about two weeks), or convert to a Japanese driver license. If you need to drive when ready and your IDP has expired, you cannot do so legally, even if your US license is still valid.

Plan ahead if you know you will be in Japan for more than a year. Order a new IDP from AATA before your current one expires, or begin the process of converting to a Japanese license. Do not let your IDP lapse while you are still driving.

Frequently Asked Questions

Can I drive in Japan with just my US driver license and no IDP?

No. Japan requires both your US license and an International Driving Permit. Driving with only your US license is illegal and can result in fines or other penalties. The IDP is a translation document that must accompany your US license at all times.

Where can I get an International Driving Permit in Japan?

You cannot get an IDP in Japan. It must be obtained in the United States before you travel. Contact AAA or AATA before your trip to order one. If you are already in Japan and your IDP has expired, you will need to renew it by mail through AATA or convert to a Japanese driver license.

How much does an International Driving Permit cost?

AAA typically charges around $20 for an IDP issued in person at an office. AATA charges a similar fee for mail orders. Fees may vary slightly by location or change over time, so check the AAA or AATA website for current pricing before you visit or explore.

Do I need a Japanese driver license if I am only visiting for a few weeks?

No. If you are visiting for less than one year, your US driver license and International Driving Permit are sufficient. You only need to convert to a Japanese license if you become a resident or plan to stay longer than one year.

What should I do if I lose my IDP while I am in Japan?

Contact AATA when ready to request a replacement. You can also contact the US Embassy or a US consulate in Japan for information. In the meantime, you cannot legally drive. Do not attempt to drive without your IDP, even if you have your US license.
