I have several other books from this author published recently and though I treasure those, I believe this book to be the most practical for my understanding of Japan.
Between the years 1962 & 1964 while with the military I resided in Japan on the Kanto Plain between Tokyo and Yokohama. During those years I visited many shrines, temples, and places of the Kami. In fact I was stationed at a Navy/Marine base named Kamiseya. Many of the questions I had and still have concerning sacred things of the Kami, Shinto, Buddha, temples, Torii gates, pagodas and shrines are addressed in this book. In addition, the numerous color photographs which exist on almost every page only heighten the understanding; as I look at many of these I know what it felt like to actually be there. The photos offer much greater realism to the text.
In addition the author traces the path of Buddhism from India through China and Korea to eventually reach Japan, where it was intermingled with both existing Shintoism and the Imperial family. The fact of the sun goddess being intertwined with the Imperial family explain why the Emperors were seen to be divine. All of this gives more understanding of just 'what' makes the Japanese to be "Japanese" than many other volumes I've read.
If you have any interest in the history of Japan concerning her religious roots that continue through present day, this is a book for you. Mr. Turnbull has issued at least 3 major books in the last few years that deal with both Japanese history and the Samurai, but this latest is the best for anyone wanting to know the force other than military that has both driven and sustained Japan through the centuries.
