As a practitioner of Wado, I don’t think I would say that "grappling" features heavily in our Karate (or at least not in the modern MMA way of looking at it) however many techniques utilise "Toru" holding, throwing and sweeping movements. We also have "Idori" which is a form ground work but again is more Aiki based rather than grappling. To an extent I think that it is fair to say that wado is less physically demanding than the other style mentioned and certainly we do not place as much emphasis on the conditioning of the body, but that said you will get fit training in Wado! As a Japanese (as opposed to Okinawan) style with its roots embedded in Shindo Yoshin Ryu Jujitsu, Wado is as not so much about physical perfection, but more about developing the mind. Therein lies the problem. There are not that many instructors around that can truly impart that knowledge. Z
