Tokkun: Japanese Drills

Tokkun is a focused Japanese practice app for the details that only become reliable through repetition. It does not try to be a textbook. Instead, it turns essential but easily confused patterns into short drills you can repeat until the answer feels automatic.

Build fast recall with Japanese number practice and verb conjugation drills, from irregular dates, time, and counters to directional verb-form changes.

FOCUSED JAPANESE DRILLS

Practice carefully curated material including:

• Numbers, dates, time, counters, and sound changes
• Verb and adjective conjugation
• Transitive and intransitive verb pairs
• Giving and receiving expressions
• Katakana and special spellings
• Fixed honorific replacements
• High-frequency special readings
• Fixed particle collocations
• Pronunciation, accent, and mora timing

BUILD YOUR OWN PRACTICES

Choose one category, narrow the scope, set the number of cards per round, and give the practice a name. Each practice keeps its own settings while card progress is shared, so the same card is never treated as a completely different memory just because it appears in another practice.

TWO CARD MODES

Use Flashcards for relaxed recall and self-assessment, or Input mode when you want an objective typing challenge. Tap Japanese text to hear its pronunciation. Favorite useful cards, review mistakes, and mark cards as mastered when they have become automatic.

SMART REVIEW OR FREE PRACTICE

FSRS schedules due cards first and adds new cards only when you have room. Prefer a quick session without a schedule? Free Practice selects a fresh random set each round without changing your FSRS plan.

SEE YOUR PROGRESS
