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 Try Lv.1-2 lessons and part of the dictionary for free. Free sign-up saves your progress and reviews. PREMIUM (ONE-TIME, NOT A SUBSCRIPTION) - All 1,515 words - Lv.3-6 lessons - Comparison mode - No further payments, ever Japanese nuance isn't something you translate. It's something you feel. Start with today's word.
