If your driver's license was issued by a country or U.S. state that is not on the National Police Agency's exempt list, converting it to a Japanese license through 外免切替 (gaimen kirikae) means you cannot skip straight to the paperwork stage. You have to sit a 学科試験 (gakka shiken, knowledge test) and pass a 技能試験 (ginō shiken, skills/practical test) on a closed course at your local 運転免許センター (driver's license center). This applies to license holders from countries including China, Brazil, Vietnam, the Philippines, India, Indonesia, Thailand, and Russia, among others — see which countries need the test if you are not sure which group you fall into. This article walks through what the two tests actually involve, why they got dramatically harder in late 2025, what it realistically costs in money and time, and how to prepare. For the full process end to end, including document prep and appointment booking, start with the full 外免切替 conversion guide.
The two tests: knowledge and skills
Everyone in the test-required group faces two separate exams on the same visit to the license center, usually in this order:
- 学科試験 (gakka shiken) — a written knowledge test on Japanese traffic law, road signs, and right-of-way rules. It is multiple choice or true/false, taken on paper or a computer terminal at the center.
- 技能試験 (ginō shiken) — a hands-on driving test performed on a closed course inside the license center grounds, not on public roads. An examiner rides with you and scores your driving against a fixed checklist.
You must pass the knowledge test before you are allowed to attempt the skills test, and most centers require both to be passed within the same testing cycle before they will issue the license. Fail either one and you come back another day to retake just that portion — but as covered below, "another day" can mean weeks, not days.
What the practical test actually grades
The closed-course skills test is not primarily testing whether you can drive a car. Most applicants already can. It is testing whether you drive the way a Japanese driving school teaches, which is a specific, somewhat theatrical style of defensive driving. Examiners are working from a points checklist, starting you at 100 points and deducting for each error; you need 70 or higher to pass. What they are watching for includes:
- Signaling a full two seconds before you move — not simultaneously with the maneuver.
- Exaggerated safety checks: mirror checks plus a visible turn of the head to check the blind spot, known as 目視 (mokushi), at every lane change, turn, and start.
- Correct lane positioning on approach to turns and through intersections.
- Clean execution of the crank (クランク), a tight right-angle turning course, and the S-curve (S字), a narrow winding section — both demand precise low-speed steering with no wheels touching the curb.
- Smooth, consistent speed control rather than hesitant braking or coasting.
The single most common reason foreign applicants fail is not a driving mistake — it's skipping or under-performing the mokushi head-turn and the two-second signal timing. Someone who has driven safely for twenty years in their home country may fail simply because their home-country habits don't include this specific choreography, and the examiner is trained to deduct points for its absence regardless of how safe the driving otherwise looks.
Most first-attempt failures are procedural, not a lack of driving skill. Applicants who drive competently by any normal standard still fail because they don't perform the exaggerated mirror-and-shoulder check, don't pause two seconds after signaling, or drift out of the expected lane position. Knowing this in advance is the single biggest edge you can give yourself.
Why pass rates crashed after October 2025
On October 1, 2025, Japan overhauled both tests for gaimen kirikae applicants, and the numbers moved sharply. The knowledge test grew from 10 questions to 50, and the passing score rose from 70% to 90%. The skills test was raised to the same difficulty level used for first-time Japanese license applicants, rather than a lighter conversion-specific standard.
According to Nikkei's reporting on National Police Agency statistics, first-attempt pass rates for the October–December 2025 period fell from roughly 92.5% to 42.8% on the knowledge test, and from roughly 30.4% to 13.1% on the skills test. In practice, this means passing on the first try is now the exception rather than the norm, and budgeting for multiple attempts is realistic planning rather than pessimism.
Realistic cost and retries
The government fee schedule itself is modest: an application fee of ¥2,550, an issuance fee of ¥2,050, and a test-vehicle usage fee of ¥1,750 charged per attempt at the skills test. A single clean pass — knowledge test on the first try, skills test on the first try — comes to roughly ¥13,000 all in.
Very few test-required applicants clear it that cleanly now. Once you factor in the ¥1,750 vehicle fee charged again for each skills retry, plus optional paid practice lessons at a private course to learn the examiner's expected choreography, the realistic total for most applicants lands somewhere between roughly ¥20,000 and ¥70,000. Paid practice sessions are entirely optional — some people pass through several retries without ever taking one — so treat them as a tool to consider, not a requirement.
Prefecture and language differences
Test-required conversions are administered by your prefecture's official 運転免許センター, and the details vary noticeably from one to the next:
- Booking and wait times: Large metro centers, especially in Tokyo, are often booked out for weeks, so a failed attempt can mean a long gap before your next chance. Regional and smaller-prefecture centers sometimes move faster.
- Course layout: The physical closed course, including exactly how the crank and S-curve are laid out, differs by center, which is one reason some applicants find it useful to see the specific course before their test date if the center allows viewing.
- Test languages: Since 2023, Japan has expanded the written knowledge test to roughly 20 languages in many prefectures, and English is commonly available. However, which languages are offered on which specific test days varies by center, so confirm directly with your prefecture's license center rather than assuming English will be available on your chosen date.
- Testing days: Expect weekday-only testing at most centers, which matters for anyone working a standard Monday–Friday job.
Because these details change and differ by location, treat your prefecture's official license center as the authority, and confirm current requirements before you book. See the documents you need for what to bring on test day.
How to prepare
Given what the test is actually grading, the most useful preparation is narrow and specific rather than general driving practice:
- Learn and rehearse the mokushi safety-check sequence — mirror, then a visible head turn — before every lane change, turn, merge, and start, until it's automatic.
- Practice signaling a full two seconds before beginning any turn or lane change, rather than signaling and moving at the same time.
- If a practice course is available near you, some applicants take a small number of paid lessons specifically to walk the crank and S-curve sections and get feedback on positioning — this is optional and not something to over-invest in, but it can shortcut a few wasted attempts for people who want it.
- Book your knowledge and skills test slots as early as you can, especially at busy metro centers, and confirm which languages are offered on your specific test date in advance.
- Plan your schedule assuming more than one attempt at the skills test — treat a first-attempt pass as a pleasant surprise rather than the baseline expectation.
