Nani?! Japanese teaches the fun, weird, real Japanese textbooks skip — gyaru slang, Kansai dialect, Edo-era speech, net slang, otaku words, Reiwa youth slang, classical Heian, and Okinawan.
Every word is checked against real sources and native usage, tagged with its era, who actually says it, and a cringe rating so you never embarrass yourself. Learn a few new words a day with spaced-repetition review and build your own collection.
Free: 5 packs, 5 new words/day, and review.
Nani?! Pro (auto-renewing subscription): unlocks all 8 packs and unlimited new words/day.
• Monthly or yearly. Billed to your Apple ID; auto-renews unless cancelled at least 24h before the period ends; manage or cancel in your Apple ID settings.
