What NihonMaster is
NihonMaster is a free Japanese-learning app for learners preparing for JLPT levels N5 through N1. Its guided curriculum teaches hiragana, katakana, kanji, grammar, vocabulary, listening, and writing through checkpoints and a structured roadmap. A placement test helps establish a starting point, while personalized review brings harder material back for practice. The app states that it covers 2,136 kanji with readings, meanings, compound words, stroke-order animation, and a writing pad. It also creates example sentences from studied material and uses VOICEVOX voices for vocabulary and sentence audio. Full-length timed mock tests cover vocabulary, grammar, reading, and listening at every listed JLPT level. Lessons, progress, and audio stay on the device for offline study, and an account is not required to begin. Android, iOS, Linux, macOS, and Windows are supported. The Free plan costs nothing, with no credit card or trial clock. A Pro tier with cloud sync and other extras is planned for later.
