Kotomora is a Japanese dictionary built for learners who want more than quick definitions.
Search in English, romaji, kana, or kanji, or draw a character by hand when you don't know its reading. Entries go well beyond a one-line gloss: readings with furigana, pitch accent, audio, example sentences, conjugations, frequency, JLPT level, related words, related kanji, and written-form notes.
Paste a Japanese sentence, or share one from any app, and the sentence analyzer breaks it down word by word, with readings, meanings, and dictionary forms.
Kotomora includes a complete grammar reference: 710 grammar points from JLPT N5 to N1, from essentials like は and ている to advanced forms like べく and とはいえ. Each page says what a form means, how to build it, and when to use it, with example sentences you can listen to, and ends with practice to check yourself. 48 comparisons put forms that say nearly the same thing side by side, like the ways to say "because," or respectful and humble keigo.
Translation guides explain how English words and phrases map to natural Japanese. Learn the difference between ありがとう, ありがとうございます, and すみません, or how words like "run," "wear," "please," and "but" change with context.
Browse words by JLPT level, part of speech, and theme, or start from curated collections: onomatopoeia, four-character idioms, proverbs, idioms, slang, keigo, counters, and Japanese-made English (wasei-eigo).
