If you’re moving to Japan from an English-speaking country and plan to drive, it’s important to understand upfront that you likely won’t get the shortcut some nationalities enjoy. Here’s the realistic path: what an International Driving Permit actually covers, and what full license conversion looks like when your country doesn’t have a reciprocal agreement with Japan.
IDP vs Full License Conversion

An International Driving Permit Buys You One Year, Not More
An International Driving Permit (IDP) is valid in Japan for at most one year from the date you enter the country — even if the permit itself has a later expiration date printed on it. Japan only recognizes IDPs issued under the 1949 Geneva Convention on Road Traffic, which most English-speaking countries’ IDPs are (the US, UK, Canada, and Australia all issue under this framework), but it’s worth confirming with your home country’s issuing authority. Either way, an IDP is a temporary bridge, not a long-term solution — you cannot simply renew it indefinitely while living in Japan.
Why the Full Conversion Process Is Harder for Most English Speakers
Japan has reciprocal agreements with roughly 20+ countries — South Korea among them — that let license holders skip Japan’s written and practical driving tests entirely during license conversion (gaimen kirikae). Most US states, the UK, Canada, and Australia do not have this reciprocal exemption. That means if you’re coming from one of these places, you should expect to actually sit both a written knowledge test and a practical driving test — this is a materially harder process than what some other nationalities go through, not a formality.
What Got Harder in October 2025
Japan overhauled the gaimen kirikae system starting October 1, 2025, and the changes hit non-exempt applicants the hardest. The written test grew from 10 questions to 50 questions, and the passing bar rose from 70% to 90% (at least 45 correct). The test also dropped its illustration-based format in favor of realistic driving scenarios. On the practical side, evaluation standards were tightened to match Japan’s provisional license driving test — historically an easier bar — and the test now follows a standardized national format.

Documents You’ll Typically Need
- Your original valid foreign driver’s license
- An official Japanese translation of that license (JAF offers this service)
- Your passport, showing you lived in the issuing country for at least 3 months after the license was issued
- Your Residence Card
- Any additional documents your specific license center requests
The Process, Step by Step
- Book an appointment at your local driver’s license center
- Submit documents for review (license issue date, proof of residency in the issuing country)
- Pass an aptitude test (vision, etc.)
- If your country isn’t exempt: sit the written test, then the practical driving test
- Once you pass everything, your Japanese license is issued
- An IDP is valid in Japan for at most 1 year from your entry date and cannot be renewed indefinitely.
- Most US, UK, Canadian, and Australian license holders do not get Japan’s reciprocal test exemption — expect both a written and practical test.
- Since October 2025, the written test requires 45/50 correct and the practical test follows stricter, standardized criteria.
- You’ll need your original license, an official Japanese translation, proof of 3+ months residency in the issuing country, and your Residence Card.
Quick Summary
| Path | International Driving Permit | Full Conversion (Gaimen Kirikae) |
|---|---|---|
| Validity | At most 1 year from entry into Japan | Same as a regular Japanese license (renewal required) |
| Testing | None — you drive on your existing license | Most English-speaking countries: written + practical test required |
| Fit for long-term residents | Temporary only, cannot be reissued indefinitely | Designed for people settling long-term |
Frequently Asked Questions
Q. Can I just get a new IDP from home and keep using it in Japan?
A. No. Japan’s recognized IDP validity is fixed at one year from your date of entry, so getting a fresh IDP issued back home doesn’t extend how long it’s recognized while you’re living in Japan.
Q. Do all foreign license holders have to take the written and practical tests?
A. No — countries with a reciprocal agreement with Japan (South Korea, for example) skip both tests. Most US, UK, Canadian, and Australian license holders do not have this exemption and should expect to take both.
Q. What changed in the October 2025 reform?
A. The written test expanded from 10 to 50 questions with a 90% passing bar (up from 70%), and the practical test now applies the same strict standard used for Japan’s provisional license test.
Q. What does the “3 months of residency” document requirement mean?
A. You generally need to show, via passport entry/exit stamps or similar records, that you actually lived in the country that issued your license for at least 3 months after it was issued.
