WaniKani is a structured learning system designed to teach 2,000 kanji and 6,000 vocabulary words through an efficient, mnemonic-based approach. The platform breaks down kanji into foundational components called radicals, making complex characters easier to learn and remember through memorable stories and associations. Using a sophisticated spaced repetition system, WaniKani personalizes review intervals for each user, presenting content at optimal times for long-term retention. The subscription-based service claims to compress eight years of traditional kanji education into approximately eighteen months through its systematic, carefully sequenced curriculum.
