Quick Answer: Since October 1, 2025, Japan's foreign license conversion process has become stricter. Applicants who must take a knowledge test now face 50 questions with a 90% pass rate, and a residence certificate with specific foreign-resident details is generally required. However, exemptions apply based on your license's issuing country or region—29 countries may skip both knowledge and skills tests. Medium- to long-term residents should confirm their exemption category and documents with their prefectural police. Short-term visitors generally cannot convert a license and should check international driving permit or foreign-license rules instead.
What is foreign license conversion, and what changed in October 2025?
Foreign license conversion (外免切替: gaimen kirikae) is the procedure to exchange a valid foreign driver's license for a Japanese one without going through a full driving school. It is governed by the Road Traffic Act and handled by prefectural police at driving license centers.
On October 1, 2025, amendments to the Road Traffic Act Enforcement Regulations tightened three areas nationwide.
- Before (through Sept. 30, 2025)
- Flexible; passport and temporary-stay proof could suffice in some cases
- After (from Oct. 1, 2025)
- Residence certificate generally required; short-stay visitors generally cannot apply
- Before (through Sept. 30, 2025)
- 10 illustrated questions; 70% pass rate
- After (from Oct. 1, 2025)
- 50 text-based questions; 90% pass rate (45+ correct)
- Before (through Sept. 30, 2025)
- On-course driving; 70% pass rate
- After (from Oct. 1, 2025)
- Added tasks (e.g., crosswalk passage); stricter scoring
| Area | Before (through Sept. 30, 2025) | After (from Oct. 1, 2025) |
|---|---|---|
| Address verification | Flexible; passport and temporary-stay proof could suffice in some cases | Residence certificate generally required; short-stay visitors generally cannot apply |
| Knowledge test (when required) | 10 illustrated questions; 70% pass rate | 50 text-based questions; 90% pass rate (45+ correct) |
| Skills test (when required) | On-course driving; 70% pass rate | Added tasks (e.g., crosswalk passage); stricter scoring |
📌 Important: The 50-question / 90% standard applies to applicants who are required to take the knowledge test. It is not a universal bar for every applicant. Licenses from certain countries or regions are exempt from one or both tests—see below.
The reforms aim to ensure applicants understand Japan's traffic rules before receiving a Japanese license, following concerns about accidents involving converted licenses.
What do you need to convert your foreign license?
Requirements vary by nationality, residence status, and issuing country. At minimum, most applicants need the following.
Core documents (typical checklist)
| Document | Notes |
|---|---|
| Valid foreign driver's license | Original only; copies are not accepted |
| Japanese translation of the license | Prepared by an authorized translator (e.g., embassy, JAF, or designated agencies) |
| Passport | To verify entry/exit and stay history |
| Proof of 3+ months' stay in the issuing country | After obtaining the license, you must have stayed in that country for a cumulative total of at least three months |
| Residence certificate with specific items (住民票・特定事項記載) | For foreign residents covered by the Basic Resident Registration Act; issued within six months |
| Residence Card or Special Permanent Resident Certificate | May be requested during the process |
| Application photo | Per license-center specifications |
| Fees | Application fee (e.g., ¥2,500 for a standard car license in Tokyo) plus issuance fee (¥2,350) |
📌 If your passport stamps do not show enough stay history, you may need additional proof-of-stay documents. Check your prefectural police page before booking.
Who needs a residence certificate?
Under the October 2025 rules, foreign nationals covered by the Basic Resident Registration Act must submit a residence certificate listing specific foreign-resident items—nationality, residence status, period of stay, expiration date, and residence card number (for medium- to long-term residents).
Foreign nationals not covered by the Act (e.g., diplomatic or official visa holders) follow a different document set defined by the National Public Safety Commission. Short-term visitors without a registered address generally cannot apply for conversion, except in legally defined special cases.
If you have not yet registered your address, see our city hall registration guide first.
How does the conversion process work?
Procedures differ by prefecture, but the general flow is as follows.
- Check eligibility — Confirm your issuing country, exemption status, and residence documents
- Make a reservation — Most centers require advance booking (online or by phone)
- Submit documents — Staff review originals at the license center
- Knowledge test (if not exempt) — 50 questions; offered in several languages at major centers
- Skills test (if not exempt) — Must be reserved separately; not available on a walk-in basis the same day
- License issuance — Receive your Japanese license (green band for converted licenses)
⏰ Time: Document review may take one visit; tests are usually scheduled on separate days. Allow several weeks from start to finish.
💰 Tokyo example fees (Metropolitan Police Department): application ¥2,500 + issuance ¥2,350 for a standard car license. Fees vary by license class and prefecture.
📌 Prefectural differences: Reservation systems, test languages, and which license centers accept which countries vary. Always check your local prefectural police website—not every center handles every issuing country.
Exemptions by issuing country
The Metropolitan Police Department and other prefectural police publish the same nationwide exemption categories. As of the current guidance, the main groups are as follows.
- 29 countries/regions: Both knowledge and skills tests waived (e.g., Germany, France, UK, Australia, South Korea, Taiwan, and most EU states—with specific US state limits)
- Indiana, USA only: Skills test waived; knowledge test still required
- All other countries: Both tests generally required
Reservation methods, test sites, available languages, and fees still vary by prefecture—confirm those details with your local police before booking.
Can tourists or short-term visitors convert a license?
Generally, no. Under the October 2025 reforms, applicants must prove a registered Japanese address via a residence certificate. Short-term visitors (Temporary Visitor status, stays of three months or less without resident registration) are not eligible for foreign license conversion in principle.
Exceptions exist for legally defined cases—such as diplomatic or official visa holders and certain event-related visitors—but these are narrow. Do not assume a hotel address or tourist visa qualifies.
If you are visiting Japan briefly and want to drive, see the next section on international driving permits and foreign-license driving rules.
How is conversion different from an international driving permit?
These are separate routes with different purposes.
- Who it is for
- Medium- to long-term residents who want a Japanese license
- Key conditions
- Registered address, 3+ months in issuing country, tests or exemptions per country
- Who it is for
- Short- to medium-term visitors driving temporarily
- Key conditions
- Geneva Convention format IDP from a convention member country; valid within one year of issue and one year of landing in Japan; "three-month rule" applies to registered residents who leave and return
- Who it is for
- Holders of licenses from designated countries (Switzerland, Germany, France, Belgium, Monaco, Taiwan)
- Key conditions
- Authorized Japanese translation attached; valid within one year of landing; same three-month rule for registered residents
| Route | Who it is for | Key conditions |
|---|---|---|
| Foreign license conversion | Medium- to long-term residents who want a Japanese license | Registered address, 3+ months in issuing country, tests or exemptions per country |
| International Driving Permit (IDP) | Short- to medium-term visitors driving temporarily | Geneva Convention format IDP from a convention member country; valid within one year of issue and one year of landing in Japan; "three-month rule" applies to registered residents who leave and return |
| Foreign license + Japanese translation | Holders of licenses from designated countries (Switzerland, Germany, France, Belgium, Monaco, Taiwan) | Authorized Japanese translation attached; valid within one year of landing; same three-month rule for registered residents |
📌 For residents: An IDP is a temporary solution. If you plan to drive long-term in Japan, conversion (or obtaining a Japanese license through driving school) is the sustainable path.
📌 For visitors: Conversion is not the right route. Check the Metropolitan Police IDP guidance and designated-country foreign license guidance for your situation.
Understanding your status of residence helps clarify which driving route applies to you.
Cultural context: why the rules feel strict
Japan's roads differ from many countries—narrow streets, left-side traffic with predominantly right-hand-drive vehicles, strict pedestrian priority at crosswalks, and unique signage. The 2025 reforms reflect a policy shift toward verifying that converted-license holders understand these rules, not just that they hold a valid license elsewhere.

FAQ
Does the 50-question test apply to everyone? No. It applies only to applicants who are not exempt based on their license's issuing country or region. If your country is on the exemption list, you skip the knowledge test entirely.
Can I take the knowledge test in English? Major license centers (e.g., in Tokyo) offer knowledge tests in several foreign languages. Confirm available languages on your prefectural police website before booking.
What happens if I fail the knowledge or skills test? You can retake the failed test on a later date, subject to reservation availability and any prefectural rules. There is no automatic pass after conversion attempts.
Does motorcycle (bike) license conversion follow the same rules? The same conversion framework applies, but license class, age requirements, and test content differ. Confirm motorcycle-specific requirements with your prefectural police.
I live outside Tokyo. Are the rules the same? The October 2025 legal reforms and exemption categories apply nationwide, but reservation methods, test sites, available test languages, and fees vary by prefectural police. Always check your local authority.
