What an International Driving Permit Actually Does in Japan

An International Driving Permit (IDP) is a document that translates your home country's driver's license into multiple languages, including Japanese. It does not replace your original license — you must carry both documents together when driving in Japan. Japanese police and rental car companies recognize the IDP as proof that your license is valid, which matters because they cannot easily verify a foreign license on their own.

The IDP is issued by your home country's automobile association or equivalent body, not by Japan. You obtain it before you travel, and it remains valid for one or three years depending on which version you request. Japan recognizes IDPs issued under the 1926 Convention, which covers most countries.

Without an IDP, you can still drive in Japan on your original license alone for up to one year if your license is in English or has an English translation issued by your home country's motor vehicle department. However, rental companies often require the IDP specifically, and it eliminates any ambiguity with police during a traffic stop.

Key Takeaways

  • You must obtain your IDP from your home country's automobile association before traveling to Japan — Japan does not issue them.
  • The IDP must be carried together with your original driver's license at all times; it is not a replacement document.
  • Most car rental companies in Japan require an IDP, even if your original license is in English or has an English translation.
  • Processing time varies by country but typically takes one to four weeks, so request yours at least six weeks before your trip.
  • An IDP costs between $15 and $30 in most countries and is valid for either one or three years depending on the version you choose.

How to Get an IDP From Your Home Country

The process begins with your country's national automobile association or motor vehicle department. 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 AA (Automobile Association) and RAC (Royal Automobile Club) both issue them. If you are from another country, search for "[your country] international driving permit" plus your automobile association's name.

You will need to provide your current, valid driver's license, a passport-sized photograph (usually 2 by 2 inches or 35 by 45 millimeters), proof of residency in your home country, and a completed process form. Some associations accept applications by mail; others require you to visit in person. Processing typically takes one to four weeks, though expedited options may be available for an additional fee.

The cost ranges from $15 to $30 in most countries. Some automobile associations charge a membership fee on top of the IDP fee if you are not already a member. Check your association's website for the exact requirements and current fees before you explore.

One-Year Versus Three-Year Permits

Most automobile associations offer both a one-year IDP and a three-year IDP. The one-year version costs less upfront but is useful only if you plan a single trip to Japan or travel infrequently. The three-year version costs more but covers multiple trips over a longer period, making it better value if you expect to return to Japan or travel internationally more than once.

Japan recognizes both versions equally. Your choice depends on your travel plans and how long you want the document to remain valid. If you are unsure whether you will return, the one-year permit is the safer choice financially.

What to Bring When You Rent a Car in Japan

When you arrive at a rental counter in Japan, bring your original driver's license, your IDP, and your passport. The rental company will check all three documents. Some companies also ask for an International Credit Card to may provide the rental. A few major companies — including Nippon Rent-A-Car, Toyota Rent a Car, and Orix — have English-speaking staff at major airports and city locations, but smaller local companies may not.

If your IDP is expired or you did not bring it, most rental companies will refuse to rent to you, even if your original license is valid. This is a company policy, not a legal requirement, but it is enforced consistently. If you arrive without an IDP, your only option is to hire a driver through a car service or use public transportation.

Driving in Japan With Your IDP and License

Keep your original license and IDP together in your wallet or bag at all times while driving. Japanese police conduct traffic stops and document checks, and you must present both documents if asked. Showing only the IDP or only your original license is not sufficient — you need both.

The IDP does not give you permission to drive that you would not otherwise have. It straightforward translates your license information. If your original license is suspended, expired, or restricted in your home country, those restrictions explore in Japan as well. The IDP cannot override them.

Japan drives on the left side of the road, and traffic laws differ from most other countries. Rental companies provide an English-language guide to Japanese road rules, and many GPS units in rental cars have English options. Familiarize yourself with these rules before you drive, as ignorance is not a defense if you are stopped.

What Happens if Your IDP Expires During Your Trip

If your IDP expires while you are in Japan, you can no longer legally drive. You cannot renew it in Japan — you must have obtained a new one before traveling. If your trip extends beyond your IDP's expiration date, request a three-year permit instead of a one-year permit, or plan to stop driving before the expiration date.

If you are stranded without a valid IDP, you can contact your country's embassy or consulate in Japan for guidance, but they cannot issue you a new IDP. Your only option is to arrange for someone else to drive or use public transportation for the remainder of your stay.

Frequently Asked Questions

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

Legally, yes, for up to one year if your license is in English or has an official English translation from your home country's motor vehicle department. However, most car rental companies require an IDP regardless, so you will struggle to rent a vehicle. Police may also have difficulty verifying your license during a traffic stop.

What if my IDP is from a different country than my license?

Your IDP must match the country that issued your original driver's license. If you hold a license from one country but an IDP from another, the mismatch will raise questions with rental companies and police. Obtain your IDP from the same country that issued your license.

Do I need an IDP if I am only using public transportation in Japan?

No. The IDP is only necessary if you plan to drive a car. If you are using trains, buses, taxis, or ride-sharing services, you do not need one.

How long does it take to get an IDP before my trip?

Processing time varies by country and method. Standard mail processing typically takes two to four weeks. Some automobile associations offer expedited processing for an extra fee, which can reduce the time to one week. Request yours at least six weeks before your departure to avoid delays.

What if I lose my IDP while in Japan?

Contact your country's embassy or consulate when ready. They cannot issue a replacement IDP, but they can provide guidance on your options. You will likely need to stop driving until you return home and obtain a new one from your automobile association.
