As I mentioned in the Release #2562 thread (Shoho Kara wa Hajimeru Otona no Eitango Renshuu)...
This is probably one of the best tools Japanese learners can use.
As long as you are familiar with hiragana/katakana and know basic Japanese, this can build up your kanji vocab well.
There is a test at the beginning to determine how much kanji you already know (or your age, lol) or you can start at Level 1 and start from scratch.
Good for those practicing for JLPT.
This was released November 22. lol only dumped now.
