Menkyo Helper
Menkyo Helper features
Everything the app does, in detail and with pictures. Free to study; Premium adds unlimited mock exams, the lesson videos, the Menkyo Drive game free at launch, Kageno all day and no ads.
Practice questions and mock exams
More than 1,100 original questions in the official ○× format, organised by chapter, each with the rule explained in your language. Five tracks: 仮免 (50 questions / 30 min), 本免 (95 incl. illustration questions / 50 min), 外免切替, 原付, 二種. The mock exam copies the timing, the pass mark and the illustration-question scoring. Mistakes come back through spaced repetition; a diagnostic test builds a personal study plan. Free: all questions and one mock exam a day; Premium: unlimited.
Kageno — your shadow study companion
A small shadow companion who lives in the app. He sits and moves on the bars and cards, cheers your right answers and, after a wrong one, offers “I can explain” — a short explanation of that question. Two forms, a chibi ninja boy and a chibi fox-girl, switch in a swirl of liquid shadow. Signed in, you can chat with him about the app, your study plan and your weak chapters in your language, and he opens the right page for you. He guides new users through the first tour, lives in a little house in the Pro navigation bar, stays silent during mock exams and while driving with Drive Coach, and can be switched off in Settings. Free: 3 minutes a day and a few chat messages; Premium: Kageno all day and many more messages.
Real on-road lesson videos
An instructor drives the real route and shows how to handle every situation in the test: moving off, intersections, pedestrians, lane changes, stopping. Instructor lessons and the Kadoma (Osaka) test course stage by stage. The first 30 seconds of every video are free without signing in; protected streaming on one device at a time; Premium unlocks everything.
Car-paper scanner
Photograph the 車検証 (or the 記録事項 sheet that comes with the electronic card), the windshield sticker or the 自賠責 certificate, and the app reads the expiry date and the plate for you to confirm. Nothing is saved until you tap Use; the photo is processed in memory and deleted immediately. The driving licence is read the same way.
Deadline vault and reminders
Licence expiry, first-licence date (the 初心者マーク year), and the 車検 and 自賠責 of up to five cars per household. Days left, when the renewal window opens, what to do and where, your prefecture licence centre with call and map, and push reminders 60, 30 and 7 days ahead in your language with the car name.
Listen mode
Every question is read aloud, then the explanation after you answer, using your phone or browser voice — 11 of the 12 languages on Android. Study on the train without looking at the screen. Nothing is sent to our server.
Road-sign trainer
Over 100 regulatory, warning, guide and auxiliary signs and road markings with the Japanese name and the meaning in your language: flashcards, sign-to-meaning and meaning-to-sign quizzes, and difference cards for look-alike signs.
Procedure guide for every prefecture
Licence centre, required documents, booking, fees, test languages, JAF translation and phone phrases for all 47 prefectures, each item with its official source link and the date it was last checked, plus a test-day checklist. Always confirm with the official centre before you go.
