Review by Charles Eicher

It's a workbook in the "Japanese for Foreigners" series, it's completely in Japanese and has exercises in increasing levels from intermediate/advanced to brainmelt/even-NS-don't-understand/advanced. My teacher used this book in a 4th year class, we got through about 5 pages of exercises and it's the best thing I ever learned about kanji. This is the sort of book you could study occasionally, year after year, and always find new things to learn and practice.
