What renshuu does

renshuu is a Japanese study app made by a small independent team. It covers vocabulary, kanji, grammar and full sentences with a spaced repetition system built for Japanese, and it follows paths for common textbooks and the JLPT. The free version is unlimited and has no ads.

Spaced repetition built for Japanese
Vocabulary, kanji, grammar and sentences
Study paths for textbooks and the JLPT
Many quiz types, including writing
Games and an active community
Web, iPhone and Android

You choose what to study, or follow a ready-made schedule matched to a textbook, the JLPT or your own goals. Words come with audio, images and example sentences, and kanji come with mnemonics and radicals. Quizzes let you answer by choosing, typing or writing.

There's a playful side too: single and multiplayer games, a mascot that rewards study with coins and manga pages, and an active community with forums and challenges. A review updated in 2025 notes there's no built-in speaking practice and that the dashboard can feel overwhelming at first.

The free version is genuinely generous, and renshuu pro adds extras if you want to support the developers. If you're serious about Japanese and want one place for vocab, kanji and grammar, start here.
