Prepare for Japan’s foreign-license conversion test with a study routine you can make your own. Gaimen brings written practice, practical driving guidance, paperwork and focused review in one place. Gaimen also covers the driving-school written tests: pick karimen (仮免) or honmen (本免) and practice in the official format. The 仮免 mock is 50 true/false questions in 30 minutes, and both the mock and your plan use only questions in the official 仮免 scope. The 本免 mock is 90 true/false questions plus 5 illustrated hazard prediction (危険予測) items worth 2 points each, in 50 minutes, with 90 of 100 points to pass. The 30 hazard scenes are original illustrations, with questions and explanations in all six languages, so you can practice in your language. Start with Today’s recommended 15-question plan, choose a written or Driving focus, or jump into Learn. The written course includes 504 original true/false questions across 20 topics. Every answer has a clear explanation and source references. Study content works offline, with no account required. For the conversion test, take a timed 50-question mock in 30 minutes, scored against the in-app 45/50 pass bar. Missed questions return in scheduled Review, and recent mocks show recurring weak topics. Set an optional test date for the written or the driving test, and your plan stays visible on Today and Driving. Optional study reminders can prompt your daily plan, count down to your test, and, for the conversion test, warn you before a written pass runs out. They are local notifications you can turn off in Settings. When your test date has passed, Today asks how it went. Pass, and you can share a 合格 card. After a conversion written pass, you can set your driving test date there. If you need another attempt, set a new date and keep everything you studied. The Documents checklist is open to everyone: where your license was issued, the documents to bring, the JAF translation, and links to the license pages of all 47 prefectural police forces, with the date the list was last checked. Your prefecture's police page stays the authority. Signs and markings is open to everyone too: 32 Japanese road signs and road markings, each with its official Japanese name, what it means and what you must do, its legal source in the Sign Ordinance (標識令), a street photo, and the practice questions that use it. Meanings are in all six languages. Then quiz yourself: pick each sign's meaning from four choices. Driving prepares you for the conversion driving check (技能確認) with 77 scenarios, safety routines, a deduction rulebook, and course guides. Missed scenarios return on a spaced schedule in Driving review, with the relevant rule. Hear 46 typical examiner phrases in Japanese, then check your ear with a listening quiz (six phrases are open to everyone). The safety routines are read aloud in all six languages, and the Course day guide includes My route: build the route you were given and drill what comes next at each step. All audio ships inside the app, so it works offline. Without a purchase you get 30 written starter questions, one full mock in any format, 3 hazard items, 12 Driving scenarios, the instant-fail list, reminders, the Documents checklist, and Signs and markings with a 6-sign quiz round. Driving is a separate one-time purchase for the practical content only. Pro is a separate one-time purchase that includes the written course, unlimited 外免, 仮免 and 本免 mocks, all 30 hazard items, Driving, and sign quiz rounds of 10 drawn from all 32 signs and markings. There are no subscriptions. Existing owners keep their access and progress. If you already own Driving, you can upgrade to Pro with a one-time upgrade purchase. Switch between English, 日本語, 中文, Tiếng Việt, Português, and नेपाली on any question. Gaimen is an independent study aid, with original questions based on public sources. It is not affiliated with any police or government body. Rules can change, so confirm details with your test center.
