Kyokushin (極真) is a style of karate originating in Japan. It is a full-contact style of stand-up fighting and is rooted in a philosophy of self-improvement, discipline, and hard training.

Karate (空手), also karate-do , is a martial art developed in the Ryukyu Kingdom. It developed from the indigenous Ryukyuan martial arts under the influence of Chinese martial arts. While modern karate is primarily a striking art that uses punches and kicks, traditional karate also employs throwing and joint locking techniques. A karate practitioner is called a karate-ka (空手家).
