Shotokan Karate of America (SKA) is a nonprofit organization teaching traditional karate-do in the United States since 1956 (most Americans had never even heard of karate in 1956). Because of SKA’s strong resolve to offer high-quality martial arts to the public, SKA has remained non-commercial, non-profit, and continues to offer authentic, traditional martial arts instruction at affordable rates under the direction and leadership of Mr. Tsutomu Ohshima, Shihan (chief instructor) through more than 140 dojos across the United States and Canada with affiliates worldwide.
