Karate (空手, Karate?) or karate-dō (空手道, karate-dō?) is a martial art that developed from a synthesis of indigenous Ryukyuan fighting methods and kempo. "Karate" originally meant Chinese hand, but was later changed to a homonym meaning "empty hand" in Japanese. It is known primarily as a striking art, featuring punching, kicking, knee/elbow strikes and open handed techniques. However, grappling, joint manipulations, locks, restraints/traps, throws and vital point striking also appear in karate. A practitioner of karate is called a karateka (空手家).

In general, there are many components to modern karate training. One common division is between the areas of kihon (basics or fundamentals), kata (forms), and kumite (sparring). Another popular division is between art, sport, and self defense training. Weapons (kobudo) comprise another important training area, as well as the psychological elements incorporated into a proper kokoro (attitude) such as perseverance, fearlessness, virtue, and leadership skills. Often in the execution of a technique, karateka are encouraged to issue a loud kiai or 'spirit shout'.
