Uechi Ryu (上地流) is a style of Karate originated by Master Kanbun Uechi (上地完文), who studied Pan Gai Noon (half-hard half soft) Kung Fu on Mainland China. His son Kanei Uechi taught the style at the Futenma City Dojo, Okinawa. Some of his more famous students are George Mattson of Boston, who authored several books on the subject, and Alan Dollar who teaches in Antioch California and is also an author of the same. Uechi Ryu emphasises toughness of the body with quick highly effective hand and foot strikes. There are no jumping spin kicks as one would find in Tae Kwon Do. The main weapons are the one-knuckle punch (shoken), spearhand (nukite) and toe kick.
