Gaimen: Japan License Test
Conversion Mock Exams & Drills
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Japan's new license-conversion written test fails most applicants. Gaimen gets you ready: 500 practice questions, real 50-question mock exams, and clear explanations.
Pass Japan's foreign-license conversion written test.
In October 2025, Japan changed the written knowledge test for converting a foreign driver's license (外免切替 / gaimen kirikae): 50 questions, a 90% pass bar, and a pass rate that fell below 45%. Gaimen is built to get you through it — in English, 日本語, and 中文.
WHAT YOU GET
• 500 original practice questions, written from Japan's road-traffic law — with a clear explanation for every answer.
• Timed mock exams in the real format: 50 questions, 30 minutes, the actual 90% pass bar, and a pass/fail verdict that shows your weakest topics.
• Topic drills across 20 areas — signs, right-of-way, pedestrians, expressways, parking, alcohol & penalties, and more.
• Spaced-repetition review that brings back the questions you miss, right before you'd forget them.
• A readiness estimate so you know when you're ready — and three languages you can switch between on any question.
WHY GAIMEN
Most apps cover the generic Japanese learner's test, in Japanese only. Gaimen targets the conversion test specifically, with carefully written, explained questions in the languages foreign residents actually read.
FREE TO START. ONE-TIME UNLOCK — NOT A SUBSCRIPTION.

See the signs — don't just read them.
New in 1.2: every sign question now shows the actual Japanese road sign, and right-of-way questions show a clear top-down diagram.
• 27 real road signs — stop, no-entry, speed, no-parking, warning signs and more
• 15 situational diagrams — intersections, priority roads, overtaking, crossings, signals
• Road markings too — centre lines, stop lines, lane arrows
Recognise the signs and read the scene the way the real 外免切替 exam tests you. Included in all six study languages — free.
