this is undoubtably THE BEST phrasebook. with cute cartoon illustrations, it is organized in a logical thematic way and very easy to use. one of things that makes it exceptional is that it combines practical getting-around information (like the tokyo train and subway system) with other useful words and phrases.
the point and speak series (japanese publisher) is huge and mainly geared towards japanese speakers who are visiting other countries around the world. the japan version is available in various editions for native speakers of other languages, so keep an eye out that you are indeed getting the english/japanese version.
this phrasebook is now available as an iphone/ipad app, which includes audio.
this book is hard to find outside of japan. if you are looking for a copy, let me know, i'd be glad to find one for you.
