It is very easy to use and makes learning Japanese easy and simple!
The book contains many phrases for a wide range of situations. Not to mention, at the end of the book is a dictionary, that translates English words in to Japanese- and also shows you how the word/phrase is written in Japanese and how to pronounce the word/phrase.
I would definitely recommend this to anyone interested in learning Japanese, or is planning on taking a trip to Japan- as it would be extremely useful.
