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, 中文, Tiếng Việt, Português and नेपाली. WHAT YOU GET • 504 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 six languages you can switch between on any question. PRACTICAL TEST (技能確認) You can already drive. On Japan's closed course you're graded on procedure — the checks, the positioning, the sequence. Gaimen's Practical Test prep covers: • The instant-fail acts (試験中止) that end the test on the spot • The −20 / −10 / −5 deduction items, grouped and explained • Spot-the-deduction ○× drills, each tied to the rule • The safety-check sequences (the 5-point look, 巻き込み, 一時停止, 踏切) • The course elements: crank, S-curve, hill start, railroad — what each tests Point values follow Japan's national scoring; always confirm specifics with your test centre. 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. Try a full mock exam and a starter set of questions for free. Unlock the entire question bank, unlimited mocks, and the review deck with a single one-time purchase. No subscription, ever.
