From words you know to conversations you can practise.
Kaiwa Days turns everyday situations into branching Japanese conversations. Choose a reply, read feedback on awkward or impolite expressions, and compare how the same message changes with the listener. No account is required.
Explore 612 Japanese conversation scenarios, from everyday errands to the hobbies you love.
464 daily-life scenarios and 148 hobby scenarios: shopping, transport, clinics, work, anime shops, games and fan events. Every scenario includes a cultural note, so you can explore the context behind the words. Compare the same intention across two or three relationships in 69 linked groups. Includes 100 added scenarios focused on travel: transport, hotels, sightseeing, shopping and travel problems. Choose travel as your learning goal to start with a station conversation.
Some scenarios require a rewarded ad to unlock. Difficulty labels are learning guides, not JLPT certification. Some content uses English as a fallback.
01
Follow a conversation by choosing your own replies. Feedback explains selected expressions that sound unnatural or impolite in context. Practise deciding what to say, with furigana or romaji when you need reading support.
02
How would you say the same thing to a friend, a senior colleague or a customer? Complete two or more linked conversations to see their expressions together. Comparison is available for supported scenario groups.
03
With gradual support reduction enabled, repeat a conversation with fewer reading aids, then try listening before revealing the other speaker’s lines. You can reveal the text when needed. Revisit collected phrases with quizzes and audio drills.
Think about your next conversation.
Order at a café. Make plans. Say how you feel. Practise exchanges that have a place beyond the textbook.
Explore scenes from daily life and hobbies in Kaiwa Days. Find a conversation that interests you, then start by choosing just one reply.
Daily-life and hobby scenarios; title search; difficulty filters; today’s recommendation and next-practice suggestions; learning-goal selection.
Branching replies, contextual feedback, grammar notes where available, cultural notes, and comparison of completed linked conversations. Optional pauses before choices and before sending a spoken reply.
Japanese text, furigana, romaji or both; meanings; optional gradual reduction of reading hints on repeat playthroughs; reveal hidden lines when needed.
Japanese text-to-speech, slow playback, read-aloud, shadowing and recall audio drills. Playback needs a Japanese voice on your device.
Phrasebook, review queue, mastery groups and function tags such as requests or refusals. Scheduled review quizzes include multiple choice, word order and fill-in-the-blank; a separate drill reviews phrases just collected.
Optional on-device speech recognition offers three-level reading feedback and pace hints. Requires a model download, a compatible device and microphone permission; it is not expert pronunciation assessment.
On supported scenarios and devices, type Japanese and let on-device AI choose from prepared replies. A summary covers politeness, clarity and vocabulary, with suggested phrases to save. Model download required; responses and ratings can be wrong. Time and turn limits apply. A demo uses a simpler reply-selection method before the model is downloaded.
Scenario completion counts, current and best streaks, earned Rest Passes that protect missed days, and sharing of a completion summary.
Optional daily reminders at a fixed time or your last study time; eight interface languages with a system-language option; practice switches, slow-speech setting and license information.
No account required; learning records are saved on your device. Core scripts are bundled. Contains ads; some scenarios unlock through rewarded ads. Ads and model downloads need internet. Some content may fall back to English.
Practise Japanese conversations at your own pace.
