What an International Driver's Permit Is and Whether You Need One
An International Driver's Permit (IDP) is a document that translates your home country's driver's license into multiple languages. It is not a separate license — it is a companion document that sits alongside your original license. Japan recognizes IDPs issued under the 1926 Convention, which most countries follow.
You need an IDP to legally drive in Japan if you plan to rent a car or drive someone else's vehicle. Japanese police will ask for both your original license and the IDP at a traffic stop. Without the IDP, you may be fined or have your rental car impounded, even if your home license is valid. The IDP proves to Japanese authorities that your license is legitimate and what it permits you to do.
If you are only visiting Japan and do not plan to drive, you do not need an IDP. If you are moving to Japan permanently or staying longer than one year, you will eventually need to exchange your home license for a Japanese license instead — the IDP is a temporary solution for visitors.
Key Takeaways
- An International Driver's Permit is issued by your home country's licensing authority before you travel and must accompany your original driver's license at all times while driving in Japan.
- The IDP is valid for one year from the date of issue, so you must obtain it close to your departure date, not months in advance.
- You cannot obtain an IDP in Japan — you must get it in your home country before you leave.
- Rental car companies in Japan will require both your original license and your IDP before they hand over the keys.
- If you stay in Japan longer than one year, you must exchange your home license for a Japanese license; the IDP expires and cannot be renewed.
How to Get an International Driver's Permit in Your Home Country
The process and cost vary by country, but the general steps are the same. You must visit the licensing authority that issued your original driver's license — in the United States, this is your state's Department of Motor Vehicles; in the United Kingdom, it is the DVLA; in Canada, it is your provincial licensing office. Contact them directly to confirm their current process, because some now accept mail-in requests while others require an in-person visit.
You will need to bring your original driver's license, a completed process form (which the licensing authority provides), a passport-sized photograph, and proof of your address. Some countries charge a small fee — typically between $10 and $30 USD equivalent — and issue the permit on the spot or within a few days. The IDP is valid for one year from the date of issue, so do not obtain it too far in advance. If you are planning a trip six months away, wait until one to two months before departure to explore.
Once you have the IDP, keep it with your original license at all times while driving in Japan. The IDP alone is not valid — you must carry both documents together. If you lose the IDP while in Japan, you cannot drive legally, and you cannot obtain a replacement in Japan. You would need to contact your home country's licensing authority to request an emergency replacement sent to you.
Renting a Car in Japan With an International Driver's Permit
Japanese rental car companies will not hand over a vehicle without seeing both your original license and your IDP. When you make a reservation online or by phone, mention that you are an international visitor and confirm that the rental company accepts your home country's license and IDP. Most major companies — Toyota Rent-a-Car, Nippon Rent-a-Car, Orix, and Budget — do accept them, but smaller local companies may have different policies.
At pickup, bring your passport, your original driver's license, your IDP, and an international credit card in your name. The rental agent will photocopy your license and IDP and may ask you to sign a form acknowledging that you understand Japanese traffic laws. Rental rates for international visitors are often higher than for Japanese residents, and you will be required to purchase collision damage waiver insurance. Ask the rental company whether your home country's auto insurance or credit card covers rentals in Japan — many do not, so the waiver is often necessary.
Before you drive away, inspect the car for existing damage and photograph or video-record the condition. Japanese rental companies are strict about damage charges, and a pre-existing scratch you did not notice can result in a large bill when you return the car.
Japanese Traffic Laws and Driving Differences You Should Know
Japan drives on the left side of the road, the same as the United Kingdom and Australia. If you come from a country that drives on the right, this will feel unfamiliar for the first hour or two. Take a short practice drive in a quiet area before you venture onto highways or into cities.
Speed limits are posted in kilometers per hour, not miles per hour. Highways typically have a 100 km/h limit (about 62 mph), and city streets are usually 40 to 60 km/h (25 to 37 mph). Police enforce speed limits strictly, and speeding fines are high. Seatbelts are mandatory for all passengers, and children under six must sit in a car seat.
Parking is expensive and often requires a parking ticket from a machine. Many parking lots in cities do not accept foreign credit cards, so carry cash. Drinking and driving is illegal with zero tolerance — even a small amount of alcohol in your system can result in arrest, license suspension, and jail time. Do not drive after drinking at all.
Toll roads are common, especially around Tokyo and Osaka. Most toll booths accept cash and Japanese credit cards, but some now accept international cards. Ask your rental company how tolls work on your specific route and whether they can be prepaid.
What Happens If You Drive Without an International Driver's Permit
Driving in Japan without an IDP is illegal, even if you have a valid home country license. If you are stopped by police, you can be fined up to ¥100,000 (roughly $700 USD, though exchange rates vary). More seriously, if you are involved in an accident, your insurance may not cover the damage because you were driving illegally. The rental car company can charge you for the full cost of repairs, and you could be held liable for injuries or damage to other vehicles.
If you are caught driving without an IDP, the police will confiscate your vehicle and may require you to appear in court. This can derail your travel plans and create legal complications that extend beyond your trip. The cost and hassle of obtaining an IDP before you leave home is far smaller than the consequences of driving without one.
Exchanging Your License for a Japanese License If You Stay Longer Than One Year
If you move to Japan or stay longer than one year, your IDP will expire and cannot be renewed. Instead, you must exchange your home country license for a Japanese license. You do this at a local prefectural police station's driver licensing center — every prefecture has one. The process is called a gaikokujin menkyō kōkan (foreign license exchange).
Bring your original home country license, your passport, proof of your address in Japan (a utility bill or rental agreement), and a completed process form. You will take a written test on Japanese traffic laws (available in multiple languages) and a practical driving test. The written test covers road signs, right-of-way rules, and safe driving practices. If you pass both tests, you receive a Japanese license valid for three to five years.
The exchange process typically takes one to two weeks. During that time, you can still drive with your home license and IDP if your IDP has not yet expired. Once you receive your Japanese license, you no longer need the IDP and should not drive with it alone.
Frequently Asked Questions
Can I drive in Japan with just my home country license and no IDP?
No. Japanese law requires both your original license and an IDP. Driving with only your home license is illegal and can result in fines, impoundment of the rental car, and insurance denial if you are in an accident. The IDP is mandatory.
How long is an International Driver's Permit valid?
An IDP is valid for one year from the date of issue. If you are planning a trip to Japan in six months, do not obtain the IDP now — wait until one to two months before you leave so it does not expire before your trip ends.
What if my home country does not issue International Driver's Permits?
Most countries that are signatories to the 1926 Convention issue IDPs. If your country does not, contact the Japanese embassy or consulate in your home country to ask about alternative documentation. Some countries issue a certified translation of the license instead, though this is less common and may not be accepted by all rental companies.
Do I need an IDP if I am only taking taxis and public transportation?
No. An IDP is only needed if you plan to drive a car yourself. If you use taxis, trains, buses, and rental services like Uber, you do not need an IDP.
Can I get an International Driver's Permit while I am already in Japan?
No. IDPs are issued only by your home country's licensing authority. You must obtain it before you travel to Japan. If you arrive without one and want to rent a car, you cannot drive legally.
