Study Japanese your way with an offline dictionary, adaptive flashcards, focused learning paths, quick games, and classic stories—no account or ads required.
Japanese dictionaries are good at telling you what a word means. They are not always as good at explaining when to use it. Sumigo helps with both. Alongside definitions, many entries include practical usage notes covering nuance, formality, similar words, and common mistakes. When you find a word you want to remember, save it and study it with the built-in spaced-repetition system.
DICTIONARY
• More than 200,000 Japanese–English dictionary entries
• Search using kanji, kana, romaji, or English
• Draw unfamiliar kanji directly in the search field
• View furigana and complete conjugation tables for verbs and adjectives
• Learn how words are actually used through detailed usage notes and examples
FLASHCARDS AND LEARNING PATHS
Review saved vocabulary with adaptive flashcards, or start with First 100 words in five small groups. Study kanji, grammar, and kana in separate paths. Choose what to practice, track progress, and set the length of each session.
GAMES
Practice your selected words, kanji, and kana in quick games. Catch the matching word, find the kanji missing from a Japanese word, or test your kana recognition. Build combos and see your score at the end of each session.

• Follow animated stroke-order diagrams
• Practice writing kanji with a guide and optional writing grid
• Study complete groups by school grade or JLPT level
