Title: Interesting, but I will not buy this book.
Review: I am a Japanese. This book is interesting, but many of slang written in this book are out of date. Most of those slang was used by oldfashioned yakuza or criminals in 20th century. Most of ordinary people in Japan don't speak like that. If you go to Japan, then talk to Japanese like this, people will be astonished, then they will recommend you not to use those words "for your own good".Okashina nihongo wo oboetemo shikata arimasen. Watashi ha minasan ni tadashii nihongo wo oboete hoshii desu. Onegaishimasu!!!
