日本人が普段使う言葉が、英語ではどのように使われいるのか、わかります。使い方も書いてあり、本来外国人向けに作られた本だと思いますが、
英語学習者にとっても有用な本だと思います。

視点も、外国人から日本という設定なので、世界から日本を見るといういみでも非常に面白い本だと思います。

ただ、内容は本のタイトル通り下品な言葉も収録されているので、その点はご注意願います。

This book is not nearly worth the 1000yen that it asks for and here's why:

It has more than 150 pages but seriously you only get a few words on each page. What's up with all the wasted blank spaces and the space-filling sketches?

It contains information that is random and incoherent. If one is at the beginning stage where he/she cannot distinguish the different ways of saying the word 'I' in Japanese, then there shouldn't be a reason for the person to learn and use seldomly used obscure slang like 'whaaazzzzaap' in Japanese. Moreover, the factual accuracy of some of the translations is questionable at best.

The worst part about this book is that it is yet another one of those phrase books that hardly provides any substantial information regarding when to use these slang and how these slang can be used in various contexts. If you are the desperate gaijin who is interested in just learning a few 'cool' Japanese so to sound hip or try to impress someone whom you wanna pick up, please do yourself a favour and avoid this book. If anything, 'How to Make Out in Japanese' is a much better book as you get the same useless Japanese phrases/expressions, but 3 times the content.
