Free · Designed for iPad. Not verified for macOS.
Ride along with Densha: learn Japanese from N5 to N1 the way you cross the Tokyo metro. Short lessons, reviews at the right time, JLPT mock exams.
Learn Japanese the way you travel the Tokyo metro. Every line is a topic, every station a lesson, and Densha, your little train, rides with you from your first hiragana all the way to JLPT N1.
A REAL PATH, FROM N5 TO N1
• More than 1,300 short lessons, organized as metro lines, from complete beginner to advanced.
• Varied exercises: multiple choice, tiles to put in order, listening, typing in kana or rōmaji.
• A yōkai to defeat at the end of each line to prove what you've learned.
REVIEWS THAT COME AT THE RIGHT TIME
• Spaced-repetition flashcards: each card comes back just before you'd forget it.
• Kanji and vocabulary decks for every JLPT level, plus decks shared by the community.
EVERYTHING TO READ AND WRITE
• Kana to trace with your finger, stroke by stroke.
• A Kanjidex, a dictionary and texts to read with audio, furigana and translation.
• Grammar explained simply, point by point.
MOTIVATION THAT LASTS
• A daily streak, a goal that adapts to your pace, and your flame on the Lock Screen.
• A station stamp book to fill, plus frames and app icons to unlock.
• Widgets for your streak and a word to review every day, a weekly leaderboard and Siri shortcuts.

A comfort and reliability update:
• The voice now reads words and kanji with the right reading: 雨 is "ame", as it should be.
• Softer vibration when you get an answer right.
• Sign in with Apple no longer asks for your name.
• A sturdier session: a network drop or flaky Wi-Fi won't sign you out.
• Fixes for rare crashes (speaking exercises, practice exams) and better protection of your data.
Enjoy the ride with Densha!
