Kotomora: Japanese Dictionary

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.

Study grammar by JLPT level, N5 to N1, with grammar points and guides that connect related patterns.

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).
