Kyokushin Karate has always been a breeding ground for professional full-contact fighters. Nicholas Pettas, Andy Hug, Francisco Filho, Glaube Feitosa, and Sam Greco, to name a few. Not to mention Georges St. Pierre, former Welterweight Champion of the UFC.
In more recent time, Full-contact karate is beginning to have it’s own “professional” bouts, with organizations like the World Fighting Kyokushin Organization sanctioning professional tournaments for prize. However, it is at the amateur level where these fighters get their start.
