Master Japanese VocabularyThe Smart Way
Learn the Core 10k — Japan's 10,000 most essential words — with smart flashcards and spaced repetition. A few minutes a day is all it takes.
HOW IT WORKS
Build vocabulary through daily recall
Torii combines curated Japanese vocabulary, typed reviews, and an SRS schedule so each word comes back when it needs practice.
Learn From Curated Decks
Start with Core 10k vocabulary, JLPT-focused sets, kana-only words, or WaniKani supplement content.
- Daily lessons introduce new words in manageable batches
- Vocabulary includes readings, meanings, parts of speech, and example sentences
- Pitch accent, furigana, and audio options support deeper study
- Prioritize, archive, or customize what enters your lesson queue
Practice With Typed Recall
Reviews ask you to produce answers, not just recognize them, so you strengthen active memory.
- Choose Japanese to English, English to Japanese, mixed, or Japanese-only reviews
- Type answers with romaji-to-kana input support
- Alternate meanings, readings, synonyms, and minor typos are handled gracefully
- Use Quick Review or audio-focused practice when you want a lighter session
Let SRS Schedule The Next Review
Correct answers move words forward through SRS stages; missed words return sooner for reinforcement.
- Words progress from Lesson through Rookie, Apprentice, Adept, Expert, and Sensei
- Missed answers move items back based on their current stage
- Daily review counts keep the workload visible
- Vacation Mode can pause scheduling while you are away
Keep Studying Anywhere
Torii is built for regular use, including offline study and flexible extra practice outside the SRS queue.
- Lessons, reviews, self-study, and browsing work from local data
- Progress syncs across devices when you are online
- Self-Study lets you drill learned, custom, or archived vocabulary
- Add custom vocabulary manually or from dictionary search
