Kairou Premium opens the full catalog: over 3,000 words spanning JLPT N5 through N3. WHY IT STICKS - Every card anchors three ways: image, sentence, sound - Real Japanese sentences, never isolated word lists - Kanji breakdowns show the characters inside every word - Words arrive in sets ordered by frequency — the Japanese you'll actually meet comes first STUDY YOUR WAY - Flashcards and guided study sets - Quizzes that check what's actually sticking - Reading mode with word-by-word sentences - Listening mode for walks and commutes — study without looking - Kana reference for hiragana and katakana - A quiet garden that grows each day you show up NO STRINGS - Everything works offline — words, audio, and images live on your phone - No account, no sign-up, no ads - A calm alternative to noisy, game-like language apps FOR YOU IF YOU - Recognize words in the app but blank on them in the wild - Want to hear Japanese as you study, not just read it - Are building toward JLPT N5–N3 vocabulary - Want studying to feel like a ritual, not a slot machine The first 400 words are free with every study mode included.
