KanjiTestZ

A minimalist bare-bones simple app to test your Japanese vocabulary.  Load one or more Japanese lists and test yourself on them in a random order.  You can test yourself on vocabulary as well as kanji.  Simple keyboard shortcuts make cycling through words quick and simple.

This app is built for students learning Japanese.  Most vocabulary lists are based on the “Adventures In Japanese” series of textbooks.  Lists based on the “Genki” textbook series are being added, and other lists of related words or kanji may be added as well.

(For non-Japanese-speakers, the kanji character in the icon means “language”.)
