I had no previous knowledge of any Japanese before I bought this book, but now; after going through the book and cassette, I can converse in Japanese on many subjects. Thebook is quite easy to get to grips with and teaches grammar and vocabulary along side "dialogues" with frequent tests. The dialogues follow the "Yamaguchi" family. It is best used with the cassette and i found that this aids pronunciation. I went through the whole book, covering two chapters a week in a small time ach day. This book helps with Japanese grammar and vocab so that the reader can make their own sentences. Along the way is some information on Japan. A brilliant book if you are thinking of visiting Japan or feel like learning Japanese. It gives very good ground for further work in the language.
