I just bought a karate book last monday. It had good pictures but was a bit of, just a ted. The techniques where the same but not. Only few things made me go hmm ok .. I don't do it excactly that way. Then somewhere inside the book I noticed it said Wado Ryu but I do Shotokan. So the question I have for you out there is: Is there great diffrence between Shotokan and Wado Ryu?
