Kyokushinkai is a style of karate founded in 1964 by Masutatsu Oyama, combining techniques from Shotokan karate, Goju Ryu karate, judo, boxing, and Muay Thai. It has a philosophy of self-improvement through mind and body control and effectiveness in combat. In addition to point sparring, Kyokushinkai also includes kata forms and competition where opponents aim to knock each other out within 3 minutes using kicks, punches, and knee or elbow strikes while wearing only light protective gear. Some of the most famous practitioners of this martial art include Bas Rutten, Georges St. Pierre, and Dolph Lundgren.
