Converting a foreign driver’s license to a Japanese license is done through a procedure called Gaimen Kirikae, which lets long-term residents swap a valid overseas license for a Japanese one without going through driving school from scratch. Depending on where your license was issued, you may only need to pass a vision and hearing screening, or you may also face a 50-question written test and a practical driving exam on a closed course. An International Driving Permit only covers you for one year from your date of entry into Japan, so anyone staying longer needs to complete this conversion before that clock runs out.
Who Can Skip the Written and Practical Tests
The first thing to check is whether your issuing country or state exempts you from testing. Japan has bilateral arrangements with roughly two dozen countries whose license holders skip both the written knowledge test and the practical driving exam. Applicants still take the aptitude screening and submit the full document set, but they walk out with a Japanese license the same day.
Countries on the exempt list include Australia, Austria, Belgium, Canada, the Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, the Netherlands, New Zealand, Norway, Portugal, South Korea, Spain, Sweden, Switzerland, Taiwan, and the United Kingdom, among others. The list can change, so confirm with your local Driver’s License Center before booking.
There is no nationwide exemption for the United States. Only holders of a valid license from Virginia, Maryland, Ohio, or Washington State are exempt from testing under separate arrangements with Japan’s National Police Agency. Every other U.S. state license holder has to complete the full testing process.
Proving 90 Days of Residency After Your License Was Issued
Whatever country issued your license, you must prove you lived there for at least 90 cumulative days after it was granted. Examiners will page through every passport you own, counting entry and exit stamps to reconstruct your travel history and confirm the license wasn’t picked up during a short visit. If your current passport doesn’t cover the period since the license was first issued, bring older passports or official immigration records to fill the gaps.
The 90 days don’t have to be consecutive. Separate stays in the issuing country can be added together, as long as the total reaches 90 days during a period when the license was valid. Failing to demonstrate this stay is the most common reason applications get rejected on the spot.
Documents to Bring
Missing a single item usually means rebooking. Bring all of the following:
- Your valid foreign driver’s license. Expired licenses cannot be converted, with no grace period.
- A Japanese translation of the license from the Japan Automobile Federation (JAF) or a recognized diplomatic mission. As of April 1, 2026, the JAF translation fee is ¥6,000, up from ¥4,000. The U.S. Embassy in Tokyo does not translate American licenses and directs applicants to JAF or private translators.
- A Certificate of Residence (Juminhyo) from your municipal office, issued within the last six months. For foreign nationals it must include nationality, residence status, and period of stay.
- Your Residence Card (Zairyu Card) showing your current immigration status.
- All passports, current and expired, for the 90-day residency check.
- One recent photograph, 3 cm by 2.4 cm, taken within the last six months against a plain background, facing forward with no hat.
The application form is provided at the center and asks for personal details, current address, nationality, and a short driving history. Every entry has to match your supporting documents; inconsistencies trigger delays.
The Aptitude Screening
Every applicant goes through a short physical screening before any other testing. Visual acuity is measured with the Landolt C chart. You need at least 0.7 combined for both eyes and at least 0.3 in each eye. Corrective lenses are allowed, and a restriction will be noted on your license if you use them. Examiners also check that you can distinguish red, yellow, and blue, the three colors used in Japanese traffic signals, and a basic hearing check confirms you can detect horns and sirens at standard volumes.
The Written Knowledge Test
Rules tightened significantly in October 2025. The written test grew from 10 true-or-false questions to 50, and the passing threshold rose from 70 percent to 90 percent. You now need at least 45 correct answers out of 50. The test is available in several languages, including English, and covers traffic rules, road signs, and right-of-way principles.
The difficulty jump is real. Questions test speed limits on different road types, rules at crosswalks and intersections, and behavior at railroad crossings. Working through a Japanese traffic rules handbook before your appointment is the practical difference between passing and rebooking weeks or months later. Applicants from exempt countries and the four exempt U.S. states skip this test entirely.
The Practical Driving Test
The practical exam takes place on a closed course inside the Driver’s License Center, not on public roads. Scoring starts at 100 points, with deductions for each error. You need 70 or higher to pass. Examiners are watching for technical control, safety awareness, and compliance with Japanese driving conventions.
Before You Start the Engine
Scoring begins before you touch the wheel. You are expected to walk around the vehicle and check underneath for obstructions. Once inside, the examiner watches for specific gestures: physically adjusting mirrors, checking the rearview mirror, and visually confirming the area behind the car before putting it in gear. Skipping any of these costs points immediately.
On the Course
Lane positioning is scrutinized heavily. Preparing for a left turn, you must move close to the left curb; for a right turn, toward the center line. Turn signals go on at least 30 meters before a turn and at least three seconds before a lane change. The course includes two signature maneuvers: the S-curve, a winding path between curbs, and the Crank, a set of sharp right-angle turns through a narrow corridor. Touching a curb during either results in heavy deductions or immediate failure.
Speed matters too. You are expected to reach the posted speed on straightaway sections rather than crawling. At every stop sign (marked “止まれ”), the car must come to a complete stop with no rolling. Throughout the run, the examiner watches for head turns at blind spots. A glance in the mirror is not enough; you have to physically turn your head for the check to count.
Automatic or Manual
You can take the test in an automatic vehicle, but the Japanese license you receive will be restricted to automatics only (marked “AT限定”). To get an unrestricted license that covers manual cars, you have to pass in a manual. Most applicants pick automatic, since the course maneuvers are demanding enough without clutch control on top.
If You Fail the Practical Test
Most applicants fail the practical on the first try. After the October 2025 rule changes, the practical pass rate dropped to roughly 13 percent between October and December 2025, from about 30 percent in 2024. Treat a first-attempt failure as the expected outcome and plan around it.
There is no mandatory waiting period between attempts, but appointment availability is the real bottleneck. Prefectural police report rising applicant numbers, and practical test slots in Tokyo have been running about three months out as of late 2025. Most centers open their calendars only 60 days in advance, so book your next slot immediately after a failed attempt.
Practicing at a licensed driving school with a Gaimen Kirikae-style closed course is the most effective preparation. One well-known school in Tokyo charges around ¥14,500 for a 100-minute session. That cost usually pays for itself by cutting the number of retakes and the months of waiting attached to each one.
What the Conversion Costs
Total cost depends on how many practical attempts you need. At a minimum, plan for:
- JAF translation: ¥6,000 as of April 2026.
- License conversion and issuance fees: roughly ¥4,000 to ¥5,000 combined, paid through revenue stamps at the center. Amounts vary slightly by prefecture.
- Juminhyo: about ¥200 to ¥400 at your municipal office.
- Photograph: around ¥800 at a photo booth.
Your First Japanese License
After passing, a photo is taken on site, you set two four-digit PINs for the IC chip, and the card is printed and handed to you. Your first Japanese license carries a green background stripe, indicating beginner status. A green license is valid until one month after your third birthday following the issue date. At renewal the stripe changes to blue, and eventually gold with a clean record. The green marking is administrative only; no highway bans, passenger limits, or similar restrictions come with it.
If Your IDP Expires Before You Finish Converting
Driving in Japan after your International Driving Permit expires and before you hold a Japanese license is a criminal offense. Under the Road Traffic Act, operating a vehicle without a valid license carries a penalty of up to three years in prison or a fine of up to ¥500,000. That is a criminal charge, not a traffic ticket, and it can affect your visa and future residence.
A common misconception is that leaving Japan briefly and re-entering resets the one-year IDP clock. It does not. If you are registered as a resident and leave for fewer than three months, the countdown keeps running from your original entry date. Only an absence of three months or longer resets the period, and authorities scrutinize whether the departure was genuine.
Given current appointment backlogs and low pass rates, the full conversion process can take four to six months from gathering documents to passing the practical. Start well before your IDP expires, not after.
