Converting a Foreign Driver's License to a Japanese License

In 2024, roughly nine in ten people passed the written test to convert a foreign driver's license in Japan. In the first three months after the rules changed on October 1, 2025, fewer than half did — the knowledge-test pass rate fell from about 92.5% to about 42.8%, with the practical test dropping just as steeply. That collapse is the single most important thing to understand before you begin gaimen kirikae (外免切替) — literally "switching a foreign license," the process of converting an existing foreign license into a Japanese one. It still lets most drivers convert without repeating the full course of driving school, but who can apply, which documents you need, and how many attempts to budget for all look different than they did a year ago.

Rule change in effect since October 1, 2025. A revision to the Order for Enforcement of the Road Traffic Act tightened gaimen kirikae nationwide — tourists can no longer apply, and the written and practical tests got noticeably harder. If you read an older guide (from before mid-2025) about this process, treat it as outdated. The requirements below reflect the post-revision system as confirmed against National Police Agency (NPA) and prefectural police sources on 2026-07-15 — see Sources at the end of this article.

What changed on October 1, 2025

For years, gaimen kirikae had a reputation as a relatively easy back door: the standard knowledge test was ten questions built around simple illustrations, and a pass required only seven correct. Address checks were loose enough that some short-term visitors applied using a hotel or temporary address. Following a string of serious traffic accidents involving foreign-licensed drivers and public criticism that the system was too permissive, Japan's National Public Safety Commission approved a stricter framework, and the National Police Agency implemented it nationwide from October 1, 2025. The headline changes:

The effect has been significant: according to Nikkei's reporting on police data, the knowledge test pass rate fell from about 92.5% in 2024 to about 42.8% in the October–December 2025 period after the revision, and the practical test pass rate fell from about 30.4% to about 13.1% over the same comparison. If you are budgeting time for this process, plan for the possibility of more than one attempt.

Who can apply

In general, you need (1) a valid driver's license from another country or region, (2) a registered residence in Japan under a mid- or long-term residence status (so that a jūminhyō can be issued to you), and (3) proof that you actually held and used the license for a period in the country that issued it, discussed below. Whether your specific license, nationality, or residence status qualifies is exactly the kind of individual determination this guide does not make — that confirmation happens at the driver's license center reception desk, with your actual documents in hand. If your situation is unusual (a license from a country you no longer live in, a recent change of residence status, a license nearing its own expiration), it is worth calling ahead or asking at the counter before you invest in a translation and book a test slot.

The document checklist

Exact requirements vary somewhat by the issuing country and by prefecture, but the core set of documents is consistent nationwide:

Some countries have additional documentation requirements or issue licenses in formats that need extra verification, and these details do change. Your prefectural driver's license center publishes a country-by-country document list — check it for your specific licensing country before you go, rather than relying solely on this general overview.

Countries exempt from the written and practical tests

Separately from the October 2025 changes above, Japan maintains a list of countries and regions whose licensing and driver-testing standards are recognized as comparable to Japan's. If your license was issued by one of these places, you generally skip the 50-question knowledge test and the practical driving test, and only need to pass a basic eyesight check alongside the document and residence review. As of this writing, the list runs to just under thirty countries and regions, including (among others) the United Kingdom, Germany, France, Switzerland, Taiwan, and South Korea, plus a short list of specific U.S. states (most U.S. states are not on the exempt list, so the state that issued your license matters).

This exemption applies to the tests only — the residence certificate and other document requirements introduced in October 2025 still apply to everyone. The exempt-country list itself is reviewed periodically and is not something this guide reproduces in full, since an out-of-date list is worse than no list. Confirm your country's current status directly with your prefectural driver's license center or the National Police Agency before assuming either way.

If you're not exempt: the knowledge and practical tests

For everyone outside the exempt-country list, gaimen kirikae now involves the tightened knowledge test and practical test described above. Some test centers offer official practice materials or past-style questions; a number of private driving schools also now offer paid lessons aimed specifically at the gaimen kirikae practical test, given how much harder it has become. Whether that kind of preparation is worth it depends on your existing driving experience and comfort navigating the test in Japanese — this guide does not endorse or recommend a specific provider.

Fees and scheduling

Fees are set at the prefectural level and can shift over time, so treat any number here as a rough example rather than a current price. For reference, Tokyo's fee schedule lists an application fee in the neighborhood of ¥2,500, plus roughly ¥2,350 for issuing the physical IC license card and a small additional fee if a dual-purpose license category is recorded — altogether commonly landing somewhere in the ¥4,000–5,000 range before any retake fees, though your prefecture may differ. Since the October 2025 tightening pushed pass rates down sharply, budgeting for at least one repeat attempt at either test is realistic for many applicants, which adds to both cost and time.

Appointment availability is the other practical constraint: application reception and test slots at driver's license centers are limited and often need to be booked in advance by phone or online, and centers in busy areas have reported bookings filling up well ahead — plan to start the reservation process early rather than assuming you can walk in and be seen the same week.

The general process

  1. Confirm your eligibility and document requirements for your specific licensing country with your local driver's license center.
  2. Get an official Japanese translation of your foreign license (JAF or an accepted alternative).
  3. Gather your remaining documents: jūminhyō, residence card, passport, photo.
  4. Reserve an appointment at your prefectural driver's license center — reception hours and booking methods vary by prefecture.
  5. Attend your appointment for document and address review, plus an eyesight check.
  6. If you are not from an exempt country: take the knowledge test, and, if you pass, schedule and take the practical test (often on a separate visit).
  7. Pay the applicable fees and receive your Japanese driver's license.

A safety and legality note

Until your Japanese license is issued, make sure whatever you are driving on is actually valid: an International Driving Permit (IDP) is only valid in Japan for one year from your entry date and only if it was issued under the 1949 Geneva Convention format (some countries issue IDPs Japan does not recognize), and a foreign license alone, without a valid IDP or without meeting the criteria for a small number of countries with bilateral recognition, generally does not authorize driving in Japan on its own. Driving without a valid license, or continuing to drive on an expired IDP, is a traffic offense in Japan. If you are unsure whether your current permit is still valid, that is worth confirming before you get behind the wheel, not after.

Where this fits into settling in Japan

Gaimen kirikae usually comes up once you have already handled the earlier layer of paperwork that every new resident works through — getting your residence card, registering your address, and setting up the basics of daily life. If you have not gone through those yet, our guides on the My Number card, opening a bank account in Japan, and getting a phone and SIM set up cover adjacent parts of that same early-residency paperwork, since several of them rely on the same residence card and address registration this process also depends on.

None of this is a substitute for checking with the office that actually issues the license. Rules that involve public safety tend to be enforced literally and to keep changing at the margins — this guide's job is to get you to the counter with the right documents and realistic expectations, not to make the final call for you.

This article is general information, not legal advice, and does not determine your individual eligibility for gaimen kirikae. Requirements depend on your nationality, licensing country, residence status, and prefecture, and can change. For an authoritative answer about your situation, contact your prefectural driver's license center directly. Content last verified against official sources: 2026-07-15. See the disclaimer.
