I bought this book more than ten years ago when I first started my Otaku phase and didn't really have that much knowledge of the Japanese language. At the time, I cherished the book. I found the phrases interesting, and used them to sound cool to my friends who knew even less Japanese than I did. We giggled together as we learned Japanese curses, insults and pick up lines. For this purpose, the book was quite useful and entertaining.
However, I have now been studying the Japanese language (in and out of classrooms) for several years. I have come to find that in a formal business situation, a lot of this language would be highly inappropriate. On the streets, most of the basic Japanese is accepted, but the slang, is a bit dated.
Also, the book really does not teach you Japanese. If you are looking for a few easy phrases to memorize and sling around, then this book can do that for you but it is by no means a definitive resource. I recommend using this only as a supplement for more in depth texts if you truly wish to learn the language.
I've only poked around this book a little bit at the bookstore. I wish I had it when I was first learning Japanese. This is how people actually talk in Japan! Yes, it helps to know the proper way to say things, but if you want to understand casual conversation you need to know what's in this book.
This one made me giggle a bit. I found it on my boyfriend's shelf and leafed through it. Some of the phrases were hunorous, but one must keep in mind it is a different culture. How we say things and what we talk about could seem weird and unbelievable to those in other countries as well.
I enjoyed the small look into the social, relationship behavior of another culture. It taught me a lot about not only the Japanese culture but also my own American one. I think I might have to pick up the second obe.
Entertaining, well-organized, and relatively up to date. Expressing emotion in Japanese has been the hardest thing so far, and this definitely helped out.
