ONI DOJO
鬼道場From your first hiragana to JLPT N1
Oni Dojo is a complete Japanese course taught by Kurenai 紅, a slightly mischievous oni sensei. Every lesson walks you through new words, grammar, a short dialogue and a checkpoint, and every sentence is voiced.
N5 to N1, with grammar explained in plain English and a checkpoint at the end of every lesson.
Over 15,000 recorded clips, so you hear real pitch and rhythm in every word and sentence.
Spaced repetition for words, kanji and grammar, plus speaking cards that make you produce the word.
Role-plays you answer by typing or out loud, with several right answers and branching endings.
44 graded stories and 38 culture articles, with a meter that shows how many words you already know.
Works offline. No ads, no analytics. An account is optional.
