Karate (空手) is a martial art developed in the Ryukyu Kingdom. It developed from the indigenous Ryukyuan martial arts under the influence of Kung Fu, particularly Fujian White Crane. Karate is now predominantly a striking art using punching, kicking, knee strikes, elbow strikes and open-hand techniques such as knife-hands, spear-hands and palm-heel strikes. Historically, and in some modern styles, grappling, throws, joint locks, restraints and vital-point strikes are also taught. A karate practitioner is called a karateka (空手家).
