What is Kanji Koohii?
Kanji Koohii is a free web-based SRS (spaced repetition system) flashcard program designed specifically for learning Japanese kanji characters. It allows users to create digital flashcards containing a kanji character, its possible readings, English meanings, and example sentences demonstrating usage.
Users can study their flashcard decks by going through review sessions where cards are shown based on an algorithm that spaces repetitions optimally for long-term retention. Newly introduced cards appear more frequently, while older learned cards appear less often. This approach leverages the scientific understanding of memory and the “spacing effect”.
Besides creating and studying digital flashcards, Kanji Koohii also features community-sourced content and discussions for each kanji entry. Users can look up detailed information on kanji that includes stroke order diagrams, common vocabulary, and forums where learners ask questions and native speakers provide insight.
By combining flashcards rooted in SRS principles with a crowdsourced wiki-style knowledge base, Kanji Koohii offers a unique and effective way to learn Japanese kanji for students at multiple skill levels. The system is entirely web-based so it accessible from any internet-connected device.
