Kairou: Learn Japanese

Finally remember Japanese — not just recognize it.

Every word in Kairou arrives as a complete memory: an illustration, a real example sentence, and clear Japanese audio. Meaning, sound, and context land together — so words stick, instead of dissolving the moment the quiz ends.

Start with the 400 most common words, free. When you've worked through a set, add the next. 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. Kairou Premium unlocks all 3,000+ words for $5.99/year, with a free two-week trial. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the period; manage anytime in your Apple Account settings.
