What an International Driving Permit Is and Why You Need One in Japan

An International Driving Permit (IDP) is a document that translates your home country's driver's license into ten languages recognized by the United Nations. It is not a separate license — it works only alongside your valid home-country license. Japan recognizes IDPs issued by countries that are signatories to the 1926 Convention on Motor Traffic, which includes the United States, Canada, Australia, and most European nations.

If you are a visitor to Japan with a valid home-country license and an IDP, you can legally drive a rental car or borrowed vehicle. Without an IDP, Japanese police will not recognize your home license as valid, even if it is current and legitimate. If you are planning to stay longer than one year or move to Japan permanently, you will need to obtain a Japanese driver's license instead — the IDP does not substitute for permanent residency driving rights.

The IDP must be obtained before you travel to Japan. You cannot get one once you arrive. The process takes place entirely in your home country through your national automobile association or equivalent government body.

Key Takeaways

  • An International Driving Permit is issued by your home country's automobile association or DMV equivalent, not by Japan, and must be obtained before you travel.
  • The IDP is valid for one or three years depending on your home country's issuing body, and it must be carried together with your original home-country license at all times while driving in Japan.
  • In the United States, the American Automobile Association (AAA) and the American Automobile Touring Alliance (AATA) are the only two organizations authorized to issue IDPs.
  • Japan recognizes IDPs from countries that signed the 1926 Convention on Motor Traffic, but not from all countries; check your country's status before paying for an IDP.
  • If you plan to live in Japan for more than one year, you will eventually need to convert your home license to a Japanese license through the prefectural driving center, not use an IDP indefinitely.

Where to Get an International Driving Permit in Your Home Country

The organization that issues your IDP depends on your nationality. In the United States, only two bodies are authorized by the State Department: the American Automobile Association (AAA) and the American Automobile Touring Alliance (AATA). Both charge a fee (typically $15 to $20) and require your valid U.S. driver's license, a completed process form, and a passport-style photograph. AAA has physical offices in most states and can issue an IDP on the same day if you explore in person. AATA operates primarily by mail.

In Canada, the Canadian Automobile Association (CAA) issues IDPs at regional offices. In the United Kingdom, the Automobile Association (AA) and RAC both issue them. In Australia, the National Roads and Motorists' Association (NRMA) and state-based equivalents handle issuance. Each country's issuing body has its own fee structure and processing time. If you are from a country not listed here, search "[your country] international driving permit" plus the name of your national automobile association or transport ministry.

Before you pay for an IDP, confirm that your country is a signatory to the 1926 Convention. Japan does not recognize IDPs from all nations. Most Western countries, Japan's neighbors (South Korea, Taiwan), and many others are signatories, but some countries are not. Your automobile association can confirm this, or you can check the United Nations Economic Commission for Europe (UNECE) list of signatories online.

Documents and Information You Will Need

Gather these items before you contact your home country's issuing organization:

  • Your valid home-country driver's license (must not be expired).
  • Your passport or national ID card (to verify identity).
  • One or two passport-style photographs, depending on your country's requirement (typically 4 × 6 cm or 2 × 2 inches).
  • A completed process form, which the issuing organization will provide.
  • Payment for the fee (typically $15 to $25 USD equivalent, but varies by country).

Some organizations accept applications in person only; others accept mail or online submission. AAA in the United States, for example, accepts walk-in applications at most offices and can issue an IDP the same day. AATA requires mail submission. Check your issuing organization's website for their specific process before you travel.

How Long an International Driving Permit Lasts and When to Renew

An IDP is typically valid for either one year or three years from the date of issue, depending on your home country's issuing body. U.S. IDPs issued by AAA are valid for one year; those issued by AATA are valid for three years. Canadian IDPs are valid for three years. Check your IDP when you receive it to confirm its expiration date.

If your IDP expires while you are in Japan, you cannot renew it in Japan. You must either return to your home country to renew it through the same organization, or you must have already converted your license to a Japanese license. If you are a temporary visitor and your IDP expires before you leave, you are no longer legally permitted to drive. Plan ahead if you are staying longer than your IDP's validity period.

What to Do When You Arrive in Japan

When you enter Japan, you do not need to register your IDP with any Japanese authority. However, you must carry both your original home-country license and your IDP together at all times while driving. Japanese police will ask for both documents if they stop you. Driving with only the IDP and no home license, or only the home license and no IDP, is not legal.

Keep a photocopy of both documents in a separate location (such as your accommodation) in case the originals are lost or stolen. If your IDP or home license is lost in Japan, contact your embassy or consulate when ready. They can issue a temporary replacement or advise you on how to obtain one from your home country while you are abroad.

If you plan to stay in Japan for more than one year, you will need to convert your home license to a Japanese license before your IDP expires. This process takes place at your prefectural driving center (運転免許試験場, unten menkyo shiken-jo) and involves a written test, a practical driving test, and submission of documents including proof of residence and your home license. The conversion process is separate from the IDP and is the only way to drive legally as a long-term resident.

Common Mistakes and How to Avoid Them

The most common mistake is waiting to get an IDP until you arrive at the airport. IDPs cannot be obtained in Japan. If you realize you do not have one after you land, you cannot legally drive a rental car or any other vehicle, and you will have no way to obtain one without leaving the country.

A second mistake is carrying only the IDP without your original home-country license. Japanese law requires both documents together. An IDP alone is not valid proof of driving authorization. Similarly, some people assume that because their home license is valid, they do not need an IDP. This is incorrect in Japan — the IDP is the required translation, and without it your home license is not recognized by Japanese police or rental car companies.

A third mistake is assuming an IDP allows you to drive indefinitely in Japan. It does not. If you move to Japan or stay longer than your IDP's validity period, you must obtain a Japanese license. Continuing to drive on an expired IDP is illegal, even if your home-country license is still valid.

Frequently Asked Questions

Can I drive in Japan with just my home-country license and no IDP?

No. Japanese law requires both your home-country license and a valid IDP. Police will not recognize a home license alone as proof of driving authorization, and rental car companies will refuse to rent to you without an IDP. The IDP is the required translation document.

How much does an International Driving Permit cost?

In the United States, AAA charges approximately $15 to $20, and AATA charges a similar amount. Costs vary by country and issuing organization. Some organizations charge additional fees for expedited processing or mail delivery. Check your specific issuing body's website for exact pricing.

What if my home country is not a signatory to the 1926 Convention?

Japan will not recognize an IDP from a non-signatory country. If your country is not a signatory, you cannot legally drive in Japan using a home license and IDP. You would need to obtain a Japanese license through the conversion or full examination process, which requires proof of residence and typically takes several weeks.

Can I renew my IDP while I am in Japan?

No. IDPs can only be renewed through your home country's issuing organization. If your IDP expires while you are in Japan, you must either return home to renew it or convert to a Japanese license. You cannot legally drive on an expired IDP.

Do I need an IDP if I am only renting a car for one day?

Yes. Rental car companies in Japan will not rent to you without a valid IDP and home-country license, regardless of how long you plan to keep the car. This is a legal requirement, not a company policy.
