Methodology

The fudami Way

Three pillars make Japanese stick: memory science, honest game design, and one connected graph. No gimmicks.

psychology

Spaced Repetition

FSRS, the state-of-the-art scheduling algorithm, plans each review for the moment just before you'd forget. Maximum retention, minimum reviews.

A Game That Respects You

Streaks, daily goals and quiet celebrations pull you back every day. XP is always tied to a real goal like JLPT N5, never a meaningless leaderboard.

One Living Graph

Kana, radicals, kanji, vocabulary and grammar form one connected graph instead of isolated decks. Mastering each node strengthens its neighbours.

Getting Started

Three steps to fluency

1

Clear the kana gate

Everything starts with Hiragana and Katakana, the sound system of Japanese. Already know them? Test out in minutes during onboarding.

2

Review daily

Short 10–20 card sessions, scheduled by the algorithm. Commute-friendly, one-handed, always progressing.

3

Watch mastery grow

Visualize your progress with our skill radar. See exactly where you excel across JLPT levels and where to focus next.
