Master Japanese vocabulary for the JLPT — from N5 to N1. Smart flashcards, spaced repetition, and daily streaks keep you on track for exam day.

Kotoba — Learn Japanese

Learn Japanese vocabulary that actually sticks.

Kotoba uses spaced repetition — the same science behind the world's best flashcard apps — to show you each word at exactly the right moment. Study a little every day and you'll remember more in a week than you would cramming for a month.

How it works Flip a card, see the word in Japanese, then reveal the meaning. Rate how well you remembered it and Kotoba schedules your next review automatically. Words you find easy come back less often. Words you struggle with come back sooner.

Built for N5 to N1 Whether you're just starting out or pushing for advanced fluency, Kotoba covers all five Japanese proficiency levels. Switch levels any time as your skills grow.

Know exactly where you stand Set your exam date and Kotoba tells you how many words to learn each day to finish on time. Watch your mastered word count climb and your daily pace adjust as you improve.
