Kyokushin kaikan (極真会館) is a style of full-contact, stand-up, karate founded in 1964 by Masutatsu Oyama (大山倍達 ,Ōyama Masutatsu) a Japanese citizen of A Zainichi Korean origin, who was born under the name Choi Yong-I (최영의).
Etymologically, Kyoku stands for "Ultimate", Shin for "Truth" or "Reality", Kai for "Organization" and Kan for "Building" or "School". The symbol of Kyokushin Karate is the Kanku, which is derived from the Kanku Kata, the 'Sky Gazing Form'.
touching at the bottom, symbolizing the peaks or ultimate points. The thick sections at the sides represent the wrists, symbolizing power. The center circle represents the opening between the hands through which the sky is viewed, symbolizing infinite depth. The whole Kanku is enclosed by a circle, symbolizing continuity and circular action.

In some Kyokushin organizations, especially outside of a tournament environment, gloves and shin protectors are worn. Children always wear head gear to lessen the impact of any kicks to the head.
Most Kyokushin tournaments follow "knock-down karate" rules in which points are awarded for knocking one's opponent to the floor with kicks, punches, or sweeps. Grabbing and throwing are generally not allowed in Kyokushin tournaments. When they are, they are legal only if performed in less than a second. Hooks are usually legal if performed for a 'split second.' Arm or hand strikes to the head, face, neck or spine are usually not permitted, but kicks to the head are allowed. If, however, the opponent turns his back while the opponent is throwing a technique, there is no penalty. Outside of Japan straight kicks to the front of the knee are usually disallowed. Knock-outs do sometimes occur and minor to moderate injuries are common, but serious injuries are rare."
Tournament fighting under knock-down karate rules is significantly different as the objective is to down an opponent. Full-contact sparring in Kyokushin is considered the ultimate test of strength, endurance, and spirit.
In Kyokushin the order of the belts are:
* White
* red (Sometimes orange)
* Blue
* Yellow
* Green
* Brown
* Black
Each colored belt had two levels, the second being represented by a stripe on through the belt.
In addition to the number of rounds of kumite as mentioned above in the Grading section, a special tradition of Kyokushin has been the 50- and 100- man kumite. The 100-man kumite was designed as a special test for advanced practitioners of the art. In these extreme examples of kumite, the subject of the test fights 50 to 100 opponents (depending on the test) in rapid succession, usually two-minute bouts separated by one-minute rest periods. The subject has to "win" (i.e., not get knocked-out) in at least 50-percent of the bouts in order to be deemed as passing the test. One example of someone who successfully completed the 100-man fight is Miyuki Miura. Reportedly, only 16 people have successfully completed the 100-man fight.
In this kata, the hands are raised and the fingers meet to form an opening through which the sky is viewed. The top and bottom points of the Kanku represent the first fingers of each hand touching at the top and the thumbs
