This book is a great reference for nearly any student of Japanese who wants to learn some common Japanese sentence structures. The book does assume that the reader knows some basics, such as simple verb conjugations, but even if one doesn't, the book is still a wonderful guide. It goes into enormous detail about many expressions of the language--too many to count--and has several examples for each (in kana/kanji, romaji, and English), to demonstrate all their possible uses. Also included are exercises and answers that the reader can practice with to guage his or her progress. The author has packed an overwhelming amount of information into this seemingly small volume, and it's simply too good a deal for anyone learning Japanese to pass up.
