Kuizu is a Japanese vocabulary quiz program I wrote for myself. It features several intermediate level word lists, flash cards, multiple choice quizzing, and matching games. It assumes you want to memorize kanji + kana pronunciation + English meaning. Auto-adjusts word frequency based on success rate, tracks progress and mastery. Can sort wordlist, select which words to use, etc.
Thanks to Laurie Hainke and Yuko Matsuda for contributing 7 word lists!
