Pick a dojo, pick a few characters, and start drilling Japanese in seconds with KanaDojo, a clean practice app inspired by Duolingo and Monkeytype. The Kana dojo covers hiragana and katakana, with base, dakuon, and yoon sets that can be selected group by group. The Kanji dojo follows JLPT levels from N5 to N1 and shows on and kun readings with meanings beside each character, and the Vocabulary dojo drills common everyday words grouped into the same five units. Four game modes keep practice varied: pick the answer, reverse pick, type the answer, or type it in reverse. Instant feedback, running scores, and streak counters make each session feel like a game. Progress pages track statistics, daily streaks, and more than eighty achievements, and pronunciation buttons read the readings aloud. Preferences control furigana, sound effects, and visual effects, and over one hundred themes plus a collection of Japanese fonts let learners set the mood. The layout adapts to desktop, tablet, and phone screens. Use it as a personal study companion, a classroom or club practice site, or a quick daily warm-up before reading manga or watching anime. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.
