🚗 Want to drive in Japan? It just got a lot harder. Until recently, foreigners could convert their home country's driver's license to a Japanese one by passing a simple 10-question true-or-false test — with a pass rate of nearly 90%. As of October 2025, the test has jumped to 50 questions, tourists can no longer apply, and the pass rate has plummeted to the 30–40% range. Here's what happened, why, and what it means for you.

What Is "Gaimen Kirikae"?

In Japan, foreigners who want to drive have three main options: use an International Driving Permit (IDP), attend a Japanese driving school from scratch, or convert their existing foreign license through a process called gaimen kirikae (外免切替, literally "foreign license conversion").

The conversion route has long been the most practical path for foreign residents. Instead of spending upwards of $2,000 and weeks at a driving school, applicants could take a written knowledge test and a practical driving test at a license center to receive a full Japanese license. For many expats, international workers, and long-term residents, this was the go-to method.

What Changed in October 2025

Japan's National Police Agency (NPA) implemented sweeping reforms to the conversion system on October 1, 2025. The changes were dramatic.

The written test expanded from 10 to 50 questions. Previously, applicants answered just 10 true-or-false questions, needing only 7 correct to pass. Now, they face the same 50-question exam that Japanese first-time applicants take, requiring 45 or more correct answers — a 90% threshold. The questions cover traffic signs, right-of-way rules, emergency vehicle protocols, DUI penalties, highway driving regulations, and other aspects of Japan's Road Traffic Act.

Proof of residency is now mandatory. Applicants must submit a juminhyo (certificate of residence), which means they need to be formally registered at a Japanese address. This effectively eliminates anyone without an established residential base in Japan.

Tourists are completely barred from applying. Visitors on short-term tourist visas can no longer apply for license conversion at all. Previously, social media posts in multiple languages circulated tips about flying to Japan on a tourist visa and converting a license during the visit — that loophole is now sealed.

Driving history verification is stricter. Officials now more thoroughly verify applicants' driving records in their home countries and their length of stay in Japan.

The Numbers Tell the Story

The impact was immediate and stark. Chiba Prefectural Police data, for example, showed the pass rate falling from 93.3% before the change to 34.4% after it, and Oita police likewise put the earlier rate at about 90%. Figures vary by location, but at many test centers more than half of applicants now fail.

More than half of all test-takers are now failing — a dramatic reversal from a system where nearly everyone passed. For context, Japanese citizens take the same 50-question test when getting their first license, but only after completing dozens of hours of classroom instruction at driving school. Foreign applicants must study on their own.

Why Japan Tightened the Rules

Several factors converged to push policymakers toward reform.

Accidents and violations by converted drivers. In May 2025, a hit-and-run that injured an elementary school child in Misato, Saitama (the arrested driver had converted a Chinese license), and a wrong-way driving incident by a Peruvian man on the Shin-Meishin Expressway in Mie were the direct triggers for the review. National Police Agency Commissioner General Yoshinobu Kusunoki announced in May that the knowledge and skills checks would be tightened.

A sharp rise in usage. Conversions had surged: 68,623 people used the system in 2024, about 2.4 times the 2015 figure (28,886), with Vietnam the largest source, followed by China and South Korea—driven by growth in technical trainees and foreign visitors.

Social media exploitation of the old system. Online communities shared detailed guides — in multiple languages — on how to pass the 10-question test through pure memorization, how to apply on a tourist visa, and even alleged leaked test questions. Some reports suggested proxy test-taking. The ease of gaming the system undermined its credibility.

A perceived fairness gap. Japanese citizens voiced frustration that they had to invest roughly $2,000 and weeks of instruction to earn a license, while foreigners could achieve the same result with a 10-question quiz. The phrase "not fair" (fukouhei, 不公平) became a recurring theme in online discussions.

How Does Japan Compare to Other Countries?

Japan's old system was, by international standards, exceptionally lenient. The new system brings it closer to the global norm.

United States — Rules vary by state. California requires 30 of 36 correct on the written test. New York requires 14 of 20. Many states offer the test in multiple languages. Some states allow direct conversion for certain countries.

Germany — EU/EEA licenses convert with minimal paperwork. For non-EU licenses (including Japanese licenses held by foreigners), both a theory exam and a practical test are required. Total costs often exceed $1,100.

Australia — Some countries have bilateral agreements allowing automatic recognition. Others require both written and practical tests. Rules differ by state and territory.

South Korea — Notably tightened its own foreign license conversion system in recent years after facing similar problems with poorly qualified drivers obtaining licenses through an easy 13-question test.

United Kingdom — Licenses from "designated countries" (including Japan) can be exchanged directly. All others must take the full UK theory and practical driving tests.

The pattern is clear: most developed nations require meaningful testing for foreign license conversion, and several have tightened their rules in recent years for similar reasons.

What This Means for Foreign Residents and Future Expats

If you're living in Japan or planning to move there, here's what you need to know.

Plan for serious study time. The 50-question test covers the full scope of Japanese traffic law. Study materials are available in multiple languages from police-affiliated sources, and several third-party apps and books have been updated for the new format. Cramming the night before is no longer a viable strategy.

Establish residency first. You'll need a valid juminhyo, which requires registering at your local city or ward office. This is a standard step for anyone living in Japan long-term but may require advance planning for those who just arrived.

Check your country's bilateral agreement status. Approximately 30 countries and territories — including Switzerland, Belgium, Taiwan, and South Korea — have reciprocal license recognition agreements with Japan. If your country is on this list, the conversion process remains relatively straightforward with less rigorous testing requirements.

Budget extra time for the practical test. The driving skills test hasn't changed in format, but it remains a separate hurdle. Many applicants report needing multiple attempts, particularly those unfamiliar with Japan's emphasis on exaggerated mirror-checking, precise lane positioning, and specific behaviors at railroad crossings.

The Bigger Picture

The consensus in Japan is that these reforms were overdue. The old system's leniency was an anomaly — one that was actively being exploited. For Japanese citizens, the change addresses a long-standing sense of unfairness. For road safety advocates, it's a necessary step toward reducing accidents.

But there's a real cost to foreign residents. Navigating 50 questions on Japanese traffic law in a non-native language is a significant challenge. Advocacy groups have called for expanded multilingual support, more accessible study resources, and possibly preparatory courses specifically designed for foreign applicants.

Every country wrestles with the same fundamental question: how do you balance road safety with accessibility for newcomers? Japan's answer, as of late 2025, is clear — safety comes first.

What about your country? Is converting a foreign driver's license easy or difficult where you live? Have you gone through the process yourself — in Japan or elsewhere? We'd love to hear your experiences and thoughts.
