I first took Aikido. I also took Tae Kwon Do, Ninjitsu, AkiJujitsu, Krav Maga, etc. This book my father gave to me after his service in World War II in Okinawa around 1945. This book has a cloth cover. My father said hit to the throat, or kiss of death, and this book shows the toughnes for fighting like no other. Whether a tournament fight or street fighter this book is a need for any fighter, of any type. No book on the market shows how to do Karata this well except this book from Japan, thats intelligence.
