What an International Driving Permit is and whether you need one in Japan

An International Driving Permit (IDP) is a document issued by your home country that translates your valid driver's license into multiple languages. Japan recognizes IDPs, but you do not automatically need one to drive there. If your home country's license is in English, you can often drive in Japan using that license alone, provided it is valid and you carry it with you at all times.

However, an IDP becomes necessary if your license is not in English or if you plan to rent a car and the rental company requires one. Some car rental agencies in Japan will refuse to rent to you without an IDP, even if your English-language license is legal. The IDP serves as proof that your home license is legitimate and that you meet your country's driving standards.

The IDP is not a replacement for your home license — you must carry both documents together. Japanese police will ask to see your home license first, then the IDP as a supporting document. An IDP is valid for one or three years, depending on which type you obtain, and it is only valid while your home license remains valid.

Key Takeaways

  • An International Driving Permit is issued by your home country's motor vehicle authority and must be obtained before you travel to Japan.
  • You need both your home license and the IDP together; the IDP alone is not sufficient to drive in Japan.
  • The process, cost, and required documents vary significantly by country — contact your local motor vehicle department for exact requirements.
  • Most IDPs are valid for one or three years and expire when your home license expires, whichever comes first.
  • Car rental companies in Japan may require an IDP even if your home license is in English, so check with your rental agency before you book.

Where to obtain an International Driving Permit in your home country

You must obtain an IDP from the motor vehicle authority in your home country before you travel. This is not something you can get in Japan or from a third-party service. The issuing body depends on where you live.

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. You do not need to be a AAA member to obtain one from them. In Canada, the Canadian Automobile Association (CAA) issues IDPs. In the United Kingdom, the Driver and Vehicle Licensing Agency (DVLA) issues them. In Australia, state-based motor registries issue IDPs — for example, Service NSW in New South Wales or VicRoads in Victoria.

If you are from a country not listed here, search "[your country] International Driving Permit" plus the name of your motor vehicle authority. Most countries have a single national body responsible for issuing them. Some countries do not issue IDPs at all; in those cases, you may be able to obtain a certified translation of your home license from a notary or translation service in Japan, though this is less reliable than an IDP.

Documents and information you will need to provide

The exact documents required vary by country, but most motor vehicle authorities ask for the same core items. You will need your valid home driver's license, a completed process form (which you can usually read from the issuing authority's website), and proof of identity such as a passport.

Most authorities also require a passport-sized photograph, typically 4 by 6 centimeters or 2 by 2 inches. Some ask for a photocopy of your license and passport; others do not. A few require proof of your home address, such as a utility bill or bank statement.

The process form itself is straightforward and asks for your name, date of birth, license number, and the date your license expires. You do not need to provide a reason for travel or proof that you are going to Japan. The entire process is routine and does not require any special documentation beyond what you would need to renew your home license.

Cost and processing time for an International Driving Permit

The cost of an IDP ranges widely by country. In the United States, AAA and AATA both charge around $20 for a one-year permit and $30 for a three-year permit, though prices vary slightly by location. In Canada, the CAA charges approximately $25 to $35 CAD. In the United Kingdom, the DVLA charges around £5.50. In Australia, costs range from $20 to $50 AUD depending on the state.

Processing time also varies. If you explore in person at an AAA office in the United States, you can often receive your IDP the same day. By mail, it typically takes one to two weeks. In the UK, the DVLA processes applications by post and usually takes five to ten working days. In Australia, processing times range from same-day (in person) to two weeks (by mail).

If you are explore close to your travel date, check whether your issuing authority offers expedited processing or rush delivery. Some do, though this usually costs extra. If time is very short, explore in person at a local office is almost always faster than explore by mail.

How long an International Driving Permit is valid and when it expires

An IDP is valid for either one year or three years from the date of issue, depending on which type you request. Most authorities offer both options, and you choose when you explore. A one-year permit is cheaper but requires renewal sooner if you plan to drive internationally again within three years.

An IDP expires on whichever date comes first: the expiration date printed on the permit itself, or the expiration date of your home driver's license. If your home license expires in two years but you obtain a three-year IDP, the IDP will stop being valid when your home license expires. You cannot renew an IDP; you must obtain a new one from your home country's motor vehicle authority.

In Japan, police will check both your home license and your IDP. If either one has expired, you are not legally permitted to drive. Before you travel, verify that your home license will remain valid for the entire duration of your stay in Japan.

What to do if you lose your International Driving Permit while in Japan

If you lose your IDP while in Japan, you can still drive legally using your home license alone, provided it is in English or another language the police can reasonably verify. However, some car rental agencies may refuse to rent to you without an IDP, and police may be more skeptical of your home license without the supporting IDP document.

You cannot obtain a replacement IDP in Japan. Your options are to contact your home country's motor vehicle authority and request an emergency replacement be mailed to you in Japan, or to contact your country's embassy or consulate in Japan to ask whether they can issue a temporary document. Processing times for mail delivery to Japan are typically two to four weeks, so this is not a quick solution.

The most practical approach is to make a photocopy of your IDP before you travel and keep it separate from the original. If you lose the original, the photocopy can serve as evidence that you obtained one, though it is not a legal substitute for the original document.

Driving rules and requirements specific to Japan

Beyond the IDP itself, Japan has specific driving rules you must follow. You must be at least 18 years old to drive in Japan. You must carry your home license and IDP together at all times while driving — not carrying them is a violation. You must also carry your passport, vehicle registration, and proof of insurance.

Japan drives on the left side of the road, opposite to the United States, Canada, and most of Europe. Speed limits are posted in kilometers per hour, not miles per hour. The national speed limit on expressways is 100 km/h (about 62 mph), and on regular roads it is typically 50 to 60 km/h in urban areas (about 30 to 37 mph).

Seatbelts are mandatory for all occupants. Drinking and driving is illegal and heavily penalized, with zero tolerance for drivers. Parking violations can result in significant fines and towing. If you are involved in an accident, you must report it to the police and obtain a police report number, which you will need for insurance claims.

Frequently Asked Questions

Can I drive in Japan with just my home license and no International Driving Permit?

If your home license is in English, you can legally drive in Japan using only your home license. However, some car rental companies require an IDP regardless, so check with your rental agency before you book. Carrying an IDP removes any ambiguity and is recommended even if not strictly required.

How long does it take to get an International Driving Permit?

In-person applications typically take one day to one week. By mail, expect one to three weeks depending on your country. If you are traveling soon, explore in person at a local office if possible. Check your issuing authority's website for current processing times in your area.

What if my home country does not issue International Driving Permits?

Some countries do not participate in the IDP system. In those cases, you may be able to obtain a certified translation of your home license from a professional translator in Japan. Contact your car rental company and the embassy of your home country in Japan for guidance on what documents they will accept.

Do I need an International Driving Permit if I am only renting a car for one day?

It depends on the rental company's policy. Many require an IDP regardless of rental duration. Others accept an English-language home license for short-term rentals. Contact the specific rental company before you book to confirm their requirements.

Can I renew my International Driving Permit in Japan?

No. You must obtain a new IDP from your home country's motor vehicle authority. You cannot renew or replace one while in Japan. If your IDP expires during your stay, you will need to rely on your home license alone and may face difficulties renting a car.
