I was reccomended this book by Iain Abernethy (author of Bunkai-Jutsu). His comment to me was "Once I started reading it, I just couldn't put it down till I'd finished it". I read the book this way 4 times!
Unfortunately, the book is about 50 years too late in some respects. The die has been set, and the Shotokan practitioners around the world are pretty much (but not completely...) going to do it the way they always have. There are however, a very few of us, who have a serious interest in uncovering the true origins of so called "modern Karate". For me, this book is not late, but smack on time....it fills in the huge gaps in understanding I have about Karate (despite enormous amounts of reading). Bruces' research, hypothesis and subsequent discussion of the material is exemplory. Like any good piece of research, he provides the salient facts with depth and conviction, yet he does not insist his observations are "the truth". There is no such thing in the case of Okinawan Karate history anyway.
To my mind, this work is probably the most important to have come forward about the subject of Karate (specifically the origins of Shuri-te/Shotokan) since Karate was introduced to mainland Japan. Quite simply, no one has ever done this before. It is ground breaking, and as such will contradict the strongly held beliefs of many Karateka. So if you are dyed in the wool JKA/JKS, then prepare to be rocked to the core. If you have an open mind, it's just going to get stretched!
