What You Need to Drive Legally in Japan
Japan recognizes an International Driving Permit (IDP) issued by your home country, but only as a companion document to your valid home-country driver's license. You cannot drive in Japan with only an IDP. You must carry both your home license and your IDP together at all times while driving. If you plan to stay longer than one year, you will need to convert your foreign license to a Japanese license through the local prefectural driving center.
Japan does not have a reciprocal agreement with most countries that allows you to straightforward exchange a foreign license for a Japanese one without testing. The conversion process requires a written exam (in English, if available at your location), a practical driving test, and a vision and medical check. Some countries have limited reciprocal agreements that waive the practical test, but the United States, Canada, Australia, and most other nations do not.
Driving with an expired IDP or without your home license present is illegal in Japan and can result in fines, vehicle impoundment, and deportation proceedings if you are a foreign national.
Key Takeaways
- An International Driving Permit is valid in Japan only when carried together with your original home-country driver's license.
- Your IDP is valid for one year from the date of issue, and Japan will not recognize it after that period, even if your home license remains valid.
- If you stay in Japan longer than one year, you must obtain a Japanese driver's license by passing a written exam and practical driving test at a prefectural driving center.
- A small number of countries (including France, Germany, and Switzerland) have reciprocal agreements that waive the practical driving test for license conversion.
- Rental car companies in Japan require both your home license and IDP, and some will not rent to drivers over 70 years old regardless of license status.
How Long Your IDP Is Valid in Japan
Your International Driving Permit is valid in Japan for exactly one year from the date it was issued by your home country's automobile association or DMV. After that date, it expires and becomes invalid, even if your home-country driver's license itself has not expired. Japan does not extend or renew IDPs — you must obtain a new one from your home country if you need to continue driving after the first year.
If you are planning a trip longer than one year, you should explore for a Japanese driver's license before your IDP expires. The conversion process typically takes four to six weeks from the date you first visit the prefectural driving center, so plan ahead. Driving on an expired IDP is treated the same as driving without a license and can result in criminal charges.
Getting a Japanese Driver's License If You Stay Longer Than One Year
To convert your foreign license to a Japanese license, you must visit the prefectural driving center (運転免許試験場) in the prefecture where you live or work. You cannot explore by mail or through an online system. The process requires four separate visits: one for initial paperwork and medical exam, one for the written test, one for the practical driving test, and one to collect your new license.
The written exam covers Japanese traffic laws, road signs, and safe driving practices. Most prefectures offer the exam in English, but availability varies — Tokyo and Osaka offer English exams regularly, while rural prefectures may not. You must pass with a score of at least 90 out of 100. The practical test is conducted entirely in Japanese and includes basic vehicle control, parking, and real-world driving on public roads. An examiner sits in the passenger seat and scores your performance.
You will also need a medical certificate confirming you are fit to drive, obtained from any doctor in Japan. The fee for the entire conversion process is approximately 2,550 yen (about $17 USD), though this varies slightly by prefecture. Processing time is typically four to six weeks from your first visit to license issuance.
Documents You Must Bring to the Driving Center
Bring your original home-country driver's license, your passport, and your residence card (if you are a resident alien). You will also need a Japanese address — a temporary address is acceptable if you have just arrived. Bring proof of your address, such as a rental agreement, utility bill, or residence card.
You will need one passport-sized photograph (4 cm × 3 cm) for the license process. Some driving centers sell photographs on-site if you do not have one. Bring your seal (inkan) or a pen for signing documents, depending on the prefecture's requirements.
If your home-country license is not in English or Japanese, bring an official translation certified by your embassy or a professional translator. Some prefectures accept translations from the Japan Automobile Federation (JAF), which can be faster and cheaper than embassy translation.
Countries with Reciprocal Agreements That Waive the Practical Test
Japan has reciprocal agreements with a small number of countries that allow drivers to skip the practical driving test during license conversion. These countries are: Belgium, France, Germany, Monaco, South Korea, and Switzerland. Drivers from these countries still must pass the written exam and medical check, but do not need to demonstrate driving ability on the road test.
Even with a reciprocal agreement, the written exam is mandatory and must be passed on the first or second attempt. If you fail the written exam twice, you must take the practical test like any other foreign driver. The reciprocal agreement does not reduce the overall timeline significantly — you still need multiple visits to the driving center and must wait for exam scheduling.
Renting a Car in Japan with a Foreign License
All major car rental companies in Japan (Toyota Rent-a-Car, Nippon Rent-a-Car, Orix, and others) require both your home-country driver's license and your International Driving Permit at the time of rental. They will not rent to you if you have only one document. Some companies also require an international credit card in your name.
Many rental companies impose an age restriction: drivers under 21 or over 70 may be refused rental, or charged a higher daily rate. This policy varies by company and location, so confirm when you book. Some companies require an International Driving Permit even if your home license is valid, while others accept only the home license if you are a resident of Japan with a Japanese address.
Rental rates in Japan are typically higher than in North America or Europe — expect to pay 5,000 to 10,000 yen (about $35 to $70 USD) per day for a compact car, plus fuel, tolls, and optional insurance. Expressway tolls are paid at toll booths and can be significant on long drives.
Common Mistakes and What Happens If You Drive Illegally
The most common mistake is driving with only an IDP and no home license, or driving after your IDP has expired. Police conduct random license checks, especially at highway toll booths and in urban areas. If you cannot produce both documents, you will be cited for driving without a valid license (無免許運転), which carries a fine of up to 1 million yen and possible jail time.
A second common mistake is assuming your home license alone is valid after your IDP expires. It is not — Japan does not recognize foreign licenses without an IDP, regardless of how new or valid your home license is. If you are stopped after your IDP expires, you will be treated as an unlicensed driver.
If you are involved in an accident while driving illegally, your insurance may not cover damages, and you may face criminal charges in addition to civil liability. Rental car companies will hold you responsible for all damages if you were driving without valid documentation.
Frequently Asked Questions
Can I drive in Japan with just my home-country license, without an International Driving Permit?
No. Japan requires both your home-country license and a valid International Driving Permit. Your home license alone is not recognized. You must obtain an IDP from your home country's automobile association or DMV before you travel.
What happens if my IDP expires while I am still in Japan?
Your IDP becomes invalid when ready upon expiration. You cannot legally drive after that date. If you need to continue driving, you must obtain a new IDP from your home country (which requires returning home or using a mail service) or convert to a Japanese license by passing the written and practical exams at a prefectural driving center.
Do I need to take the practical driving test if I am from a country with a reciprocal agreement?
No, drivers from Belgium, France, Germany, Monaco, South Korea, and Switzerland can skip the practical test. However, you must still pass the written exam in Japanese (or English if available) and complete the medical check. The written exam is the main hurdle for most foreign drivers.
Can I convert my foreign license to a Japanese license without taking any tests?
Only if you are from one of the six countries with reciprocal agreements, and even then you must pass the written exam. All other drivers must pass both the written and practical tests. There is no way to convert a foreign license without at least the written exam.
How much does it cost to rent a car in Japan, and do I need both my license and IDP?
Daily rental rates range from 5,000 to 10,000 yen for a compact car, plus fuel and tolls. Yes, you must present both your home-country license and your International Driving Permit at the rental counter. Some companies will refuse to rent if you cannot produce both documents.
