What does this book have to do with Shotokan you ask? Well, some advanced Shotokan practitioners who are into studying kata applications believe that movements from karate kata contain Ju-jutsu moves such as joint locks and throws. I bought the book on the recommendation of one such practitioner and when I first looked at the book I thought there was no way this stuff had anything to do with Shotokan kata. After some prodding and a harder look, lo and behold, some of the techniques these Daitoryu guys practice are right there in our katas! On page 120-121 you've got movements 11 and 12 from Heian Sandan. Page 140 has the ending of Jion. Page 144 has movement 6 from Bassai Dai. I'm sure there's more that I haven't discovered yet. Get this book, it's cool.
