Full RTK set — every kanji from Remembering the Kanji
Japanese students spend 12 years learning these kanji in school. With FSRS spaced repetition and ~20 min/day of consistent reviews, many learners work through the full set in 1–2 years — your actual pace depends on consistency and retention.
Smarter Scheduling
Most SRS tools use fixed intervals — review every N days regardless of how well you actually know the item. Kanji Kraken uses FSRS, the open-source algorithm behind Anki, which adapts intervals to your actual memory strength.
The result: items you know well get pushed further out, items you struggle with come back sooner. Independent studies show FSRS reduces total review volume by around 30% compared to fixed-interval SRS while maintaining the same retention rate.
