If your are studying/learning conversational Japanese (and/or trying to email messages in romanized Japanese), you will be hard pressed to find a better reference guide. This dictionary is not for the beginner (or anyone casually interested in just memorizing/speaking “canned” Japanese phrases), but will prove to be extremely valuable after a year or so of dealing with conversational Japanese. In addition to extensive, but easy to follow definitions, there are numerous illustrative sentences (in romanized Japanese and English) showing word usage. They are there to tutor you (and, of course, expand your skills) in a user-friendly manner. An expensive book, but well worth it! The gold standard in this market, so far. WILLIAM FLANIGAN, PhD.
