Although this book is filled with helpful information, for example, "recommended tours if you have 1 day, 3 days, or 5 days", or "Top 10 Japanese experiences", the (rich, culturally inept) woman who wrote this book intended this for a very specific demographic. This causes a whole plethora of problems when trying to use the book, particularly if you are young, can speak some Japanese, or would like a Real Japanese Experience. Why?
1. Reviews for restaurants and hotels seem to focus on restaurants that serve Western food and speak English (how dare they speak Japanese in Japan!) and Western style hotels that have beds, rather than Japanese styled tatami mat rooms and futons. The humbling experience of entering a small hole-in-the-wall restaurant and pointing at other people's dishes or the pictures on the menu and eating foods you've never seen or heard of-or staying at a fairly inexpensive hotel sleeping on the floor in a futon-is top notch! I felt this book really neglected to mention a lot of these opportunities for cultural experiences, and I found that frustrating when looking for ideas.
2."And what good is a book with no pictures?" Alice wondered...Many of the best ways to get excited about a place is to first see pictures. There are very few, if any pictures in this book.
3. She refers to the Japanese language as "symbols".
4. In addition, rather than giving the Japanese characters for the cities, towns, restaurants and hotels she recommends you visit on that same page (this is very helpful because English translations are not always written, but you can easily make sure you're in the right place simply by comparing the book with the sign), she puts them all in an appendix at the back for inconvenient referencing. Including both the Japanese character and Japanese pronounciation of each location is extremely helpful.
Overall, the book will assist you in having a wonderful English tour of Japan, but I think you may miss out on some great Japanese experiences that do not require a lot of money (which many of her suggestions do require). Of course, this will involve a little bit of work and discomfort on the part of the tourist (although by no means Japanese fluency). Nothing compares to the satisfaction of having successfully ordered yakisoba in broken Japanese!
Bottom Line: This book is better used as supplemental reading to another book, although the beneficial descriptions of must-sees in Japan that are the most helpful in this book can really be found in just about every other guide book.
