Japan tightens foreign license conversions with residency checks and tougher driving tests

New rules close the conversion route for tourists

Japan tightened its rules for converting foreign driving licenses on October 1, 2025, ending access for nonresidents and introducing tougher knowledge and driving skills checks. Foreign residents who want a Japanese license now face more paperwork, greater preparation and a higher standard for showing that they understand local traffic rules.

The changes follow a series of accidents involving drivers who held converted licenses and mark the most substantial reset of the conversion system in years. They address two central concerns: whether applicants have a verifiable address in Japan and whether the checks adequately assess their knowledge and driving ability.

Police figures show that 68,623 people obtained Japanese licenses through conversion in 2024, more than double the number a decade earlier. Vietnamese citizens were the largest group, accounting for 16,681 conversions, followed by Chinese and South Korean nationals.

Police also recorded 7,286 crashes in 2024 in which foreign drivers were assigned the highest share of fault. That was a record and represented about 2.7 percent of all crashes nationwide. Those figures, together with several prominent incidents, intensified debate over the requirements for obtaining a Japanese license through conversion.

The previous system allowed visitors staying for short periods to use a hotel or other temporary lodging as their address. Its knowledge check consisted of just 10 questions, with seven correct answers enough to pass. Lawmakers in the Diet questioned whether such a brief test could establish a sufficient understanding of Japanese road rules.

The reforms replace that arrangement with checks tied more closely to registered residence and a substantially longer examination. The main dates are:

• 2024: License conversions reached 68,623, while crashes in which foreign drivers bore the highest share of fault reached 7,286.
• October 1, 2025: The new residency requirements and stricter knowledge and practical checks took effect.
• October 2, 2025: Applicants seeking conversion are subject to the revised system.

Who can apply under the residency rules?

Nonresidents can no longer convert a foreign license in Japan. A residence certificate, known as a Juminhyo and issued by a municipal office, is now a central application requirement. Tourists and other visitors staying for short periods who are not on the resident registry lose access to the conversion route.

The general requirement applies regardless of nationality, although alternative documentation is available for certain applicants. Japanese citizens who live abroad can still convert a foreign license when they return by presenting alternative proof, such as a family register certificate, instead of a residence certificate.

Special categories, including diplomats and certain organization members, may also be recognized through documents issued by their organizations. Applicants in these categories should confirm the requirements with the prefectural licensing center handling their application.

Address verification was one reason officials tightened the system. When applicants used hotels or other temporary lodging, authorities could find it harder to follow up after a traffic violation or crash. A residence certificate connects the license holder to a verifiable address on the resident registry, helping with notifications, investigations and compliance.

Foreign nationals also face a tighter rule when renewing a converted Japanese license. They must still have a residence certificate at renewal. A holder who has left Japan and is no longer on the resident registry will be denied renewal.

Converted licenses otherwise follow standard renewal cycles. The practical consequence is that residency matters both when a foreign national first applies and when the license later needs renewing.

The knowledge test grows from 10 questions to 50

Applicants who must take the knowledge examination now face 50 questions and need a score of at least 90 percent. That means answering at least 45 correctly, compared with seven out of 10 under the previous system.

Licensing centers continue to offer versions in about 20 languages. The examination is based on text, while explanations at the counter and other guidance are usually given in Japanese. Applicants may therefore need to prepare for both the test itself and the administrative steps around it.

The expanded examination places more weight on realistic traffic situations and the rules that guide safe driving in Japan. Subjects include pedestrian priority at crosswalks, right of way at intersections, stop lines and signals at railway crossings, and suitable speeds on narrow residential roads.

Questions also cover mirrors, hazard lights, road signs, pavement markings and penalties for key violations. Applicants need to understand how these rules work together in everyday situations, rather than prepare only for a short set of questions.

Study materials such as the Rules of the Road handbook are available in several languages. They can help applicants prepare for both the knowledge examination and the practical check.

What examiners expect on the driving course

The practical check still takes place on an enclosed course at a prefectural licensing center, but assessment has become stricter. Examiners pay closer attention to pedestrian crossings, railway crossings and other places where mistakes can create particular danger.

Hazard scanning, signaling and lane discipline are also part of the assessment. Hazard scanning means actively looking for something that could require a response, such as a pedestrian approaching a crossing or a cyclist moving into the vehicle's path.

Drivers are expected to use mirrors and turn their heads to check blind spots, signal at the correct distance before turning, and stop fully at stop lines. At railway tracks, the expected sequence includes a complete stop followed by a deliberate look left and right.

Examiners also watch whether candidates look ahead for pedestrians and cyclists at crossing points and control the vehicle smoothly in tight spaces. These detailed procedures may require preparation even from applicants accustomed to driving elsewhere.

Small procedural errors account for many unsuccessful first attempts. Practice in a training car, particularly with an instructor who can explain local testing conventions in the applicant's language, can improve the chances of passing.

Officials describe the purpose of the tougher checks as keeping conversion available to qualified residents while requiring them to demonstrate a clear grasp of Japanese traffic rules and testing procedures. The revised knowledge and driving checks work alongside the tighter identity and address requirements.

Which licenses qualify for test exemptions?

Conversion requirements fall into two broad groups. Some applicants can complete conversion through document checks without taking the knowledge or practical examination. Others must take both examinations, alongside the required paperwork and vision checks.

The category depends on where the foreign license was issued and whether the holder can show that they lived in that country or region for at least three months after the license was issued. A valid foreign license and evidence of that period of residence are essential to the exemption arrangements.

Holders of licenses from the following countries and regions are generally exempt from both examinations when they meet those conditions:

• Australia, Austria, Belgium, Canada and the Czech Republic.
• Denmark, Finland, France, Germany and Greece.
• Hungary, Iceland, Ireland, Italy and Luxembourg.
• Monaco, the Netherlands, New Zealand, Norway and Poland.
• Portugal, Slovenia, South Korea, Spain and Sweden.
• Switzerland, Taiwan and the United Kingdom.
• The United States states of Colorado, Hawaii, Maryland, Ohio, Oregon, Virginia and Washington.

Indiana license holders are typically exempt from the practical examination but must take the knowledge examination. Applicants whose licenses were issued outside the listed jurisdictions must take the new examination of 50 questions and the driving check on a licensing center course.

The residence requirement after issuance is separate from the requirement to establish an address in Japan. Applicants must prepare evidence covering both their eligibility to use the foreign license for conversion and their current residency documentation.

Visitors still have other ways to drive legally

Visitors staying for short periods can continue to drive in Japan through established arrangements separate from conversion. One route is a valid International Driving Permit, or IDP, issued under the 1949 Geneva Convention by a country that is party to that treaty.

The other route applies to holders of licenses from Switzerland, Germany, France, Belgium, Monaco or Taiwan. They can drive with their original license accompanied by an official Japanese translation.

These arrangements are intended for short periods of driving in Japan. An IDP or translated license does not replace conversion for people who become residents.

Some countries, including China and Vietnam, do not issue an IDP. Citizens from those places who wish to drive in Japan need to convert a license or obtain a Japanese license through the standard tests at a licensing center. With conversion now restricted to residents, tourists from those countries cannot use a temporary address to obtain a Japanese license through that route.

For travelers eligible to use an IDP or one of the designated translated licenses, the practical focus remains on having the correct documents before renting or driving a vehicle. The reform changes access to conversion while leaving those visitor arrangements available.

Documents applicants need to prepare

Prefectural requirements can vary, but licensing centers follow a common set of document checks. Applicants should confirm the local checklist and appointment arrangements before visiting, especially when a driving examination will require more than one trip.

Translations must come from an authorized body, such as the Japan Automobile Federation, known as JAF, or a relevant embassy. Authorities are also checking the authenticity of foreign licenses and their translations carefully.

The common checklist includes:

• A valid foreign driving license.
• A passport.
• An official Japanese translation of the foreign license from JAF, a relevant embassy or another authorized body.
• A residence certificate issued by the municipal office, or accepted alternative documentation where applicable.
• A residence card for foreign residents staying for medium or long periods.
• One recent photograph meeting the required size and format.
• Any Japanese license the applicant currently holds or held previously.
• An International Driving Permit, if applicable.
• Proof of residence in the issuing country for at least three months after the foreign license was issued.
• Additional travel history evidence if the passport lacks entry or exit stamps.
• The necessary fees and any corrective lenses required for driving.

Document verification can take longer when records or passport stamps are difficult to interpret. Preparing supporting travel records in advance can help avoid repeat visits caused by missing evidence.

How the conversion process works

Applicants should first check whether their prefecture requires or offers reservations. Making an appointment early and assembling the complete set of documents before attending can reduce delays.

The usual sequence is:

• Book an appointment where required or available.
• Obtain the official Japanese translation and gather the required documents.
• Submit the application and documents for verification at the licensing center counter.
• Complete eye and color vision checks.
• Take the knowledge examination in an available language, unless exempt.
• Schedule and complete the driving examination on the enclosed course, if required.
• Pay the issuance fees and collect the Japanese license after passing the required checks.

Applicants who need the practical examination should plan for multiple visits. Language options for the written examination do not necessarily extend to the counter, where explanations and instructions are usually in Japanese.

The combination of translation, travel history checks, examinations and scheduling means preparation needs to begin before a license is required for daily life or employment. A complete application is particularly useful where appointment availability is limited.

What changes for residents, employers and tourism

Foreign residents from countries requiring both examinations face the greatest preparation demands. Technical intern trainees, students and new employees who need to drive for work may require help arranging translations, finding study materials and setting aside time for driving practice.

Employers may need to account for those steps when planning when a new worker can begin driving duties. Scheduling can be difficult in large cities, making early reservations useful for shortening the process.

Driving schools report steady demand for instruction in English and other languages. Some provide handbooks and videos in multiple languages, while lessons often concentrate on the test sequence, examiner expectations and common errors that cause otherwise capable drivers to fail.

Car rental firms and tourism operators expect fewer attempts by visitors staying for short periods to obtain Japanese licenses. Eligible travelers will instead need to focus on the IDP route or the translated licenses accepted from Switzerland, Germany, France, Belgium, Monaco and Taiwan.

The reforms connect three parts of the system: eligibility to apply, proof of knowledge and skill, and the ability to reach the license holder at a registered address. Qualified residents retain a route to conversion, with examination exemptions still determined by the issuing jurisdiction and the required residence history.

For foreign nationals, maintaining the required residency documentation will also matter at renewal. Japanese citizens living abroad and applicants in special categories should confirm which alternative documents their prefectural licensing center accepts.
