This quiz includes words on Peter van der Woude's JLPT Level 4 Vocabulary List (July 4, 2006 - Used with permission.) which includes definitions from Jim Breen's Japanese Dictionary (EDICT) (C) 2001-2003.
NOTE: CK adapted the na-adjectives.

An Academic Associate from The Japan Foundation, Los Angeles suggested that I put a disclaimer on my site stating "...that it does not offer any official information on the JLPT. In fact there are no official lists of vocabulary to choose from. Your lists should be viewed as useful tools, not a comprehensive guide."
