Gaimen Kirikae - JP Licence

Since Oct 2025: 50 questions, 30 minutes, 45 to pass. 497 questions, each showing the rulebook text it rests on.

Practice for the written test (chishiki kakunin) you sit when converting a foreign driving licence to a Japanese one. Japanese, English and Simplified Chinese — switch any time.

■ The test changed in October 2025 It went from 10 questions to 50: you have 30 minutes and need 45 correct (90%). Six wrong and you fail. The mock exam here uses exactly those conditions.

■ Every question shows its source Questions are drawn from the Rules for Road Use published by the National Police Agency. After each answer you see which chapter and section it rests on, plus the original Japanese sentence, word for word. When you doubt an answer, you don't have to take our word for it.

■ What's inside · 497 questions across all 11 chapters · Meanings of signals, signs and road markings · A 50-question, 30-minute mock exam matching the real thing · Redo only the ones you got wrong

■ Find out whether you even have to sit it Pick the country that issued your licence and see whether the written and practical tests apply. 29 countries and regions are exempt; the United States depends on the state — Indiana is exempt from the practical test only, and you still sit the written one.

■ The paperwork Original licence, translation, residence certificate, proof of stay, booking, what to bring on the day — eight steps as a checklist you can tick off.

■ Pricing Chapters 1 and 4 are free. The rest, and the mock exam, are a one-time purchase — not a subscription.

■ Works offline Questions and explanations ship inside the app. Your answers stay on your device and are never uploaded. No account, no sign-up.
