A small, focused practice.
ippun is built around a simple idea: a single minute of careful attention, repeated, builds real fluency. Each round gives you an anchor character and a tray of drifting kanji — your job is to find the compounds that fit, before the timer runs down.
No streaks to guilt you. No notifications to interrupt you. Just a calm, repeatable loop you can return to whenever you have the time.
What's inside
Designed with care.
Built for short sessions
Every round lasts about a minute. Play on the train, between meetings, or before bed — it fits.
Thoughtful difficulty
Beginner and Intermediate tracks, with compounds chosen and reviewed by native speakers.
Private by design
No accounts required. No personal data collected. Analytics are anonymous and can be switched off entirely.
English and 日本語
Fully localized in both languages, with furigana readings on every compound.
