About this app

Stop translating. Start feeling Japanese.

Onomanabi teaches Japanese onomatopoeia — the sound and mimetic words that carry nuance no dictionary translation captures — through animation, context, and comparison. Built for intermediate-to-advanced learners (N3–N1) and Japanese teachers alike.

WHY ONOMATOPOEIA
"Doki-doki." "Zaa-zaa." "Kira-kira." Japanese is full of words whose real meaning lives in a feeling, not a translation. Onomanabi makes that feeling visible.

FEEL IT THROUGH MOTION
Every word comes with an animation that shows its movement, intensity, and texture — so you feel the difference between "zaa-zaa" and "para-para" instead of just reading about it.

COMPARISON MODE
See closely related onomatopoeia side by side, with native-speaker notes on the decisive difference — the nuance dictionaries flatten out.

QUIZZES THAT STICK
Multiple quiz types (4-choice, typing, comparison fill-in-the-blank) with mistake-prioritized review.

LEVELS & COLLECTION
A guided level system and word-collection progress, plus a daily word and category completion to keep you coming back.

FOR TEACHERS
A category- and level-organized reference for a subject most textbooks barely cover.

FREE TO START
