Ashihara kaikan is a modern full contact street karate developed from Kyokushin karate by Hideyuki Ashihara with influences from various martial arts including Muay Thai, Pankration, and Jujutsu with an emphasis on Sabaki, using footwork and techniques to turn an opponent's power and momentum against them and to reposition oneself to the opponent's "blind" spot. The style is focused on practical application in a real fight including multiple attackers.
