Hey everyone! 👋 I’m the creator of KotoJutsu, and I’m really excited to finally share it here. I built KotoJutsu because I wanted a structured way to learn Japanese without having to jump between a bunch of different resources. It covers everything from hiragana and katakana to JLPT N5–N1, with vocabulary, kanji, grammar, reading, flashcards, spaced repetition, and practice exercises. It’s completely free and has no ads. The English version just launched a few days ago, so I’d especially love feedback from Japanese learners outside of France. 🇯🇵 If you try it, let me know what you think — and what you’d like to see added next!
