K-1 is a martial arts fighting sport which fuses centuries of tradition from martial arts such as karate, kung fu, tae kwon do and kickboxing (the "K") into a thoroughly modern and electrifying spectator sport, to determine the single best stand-up fighter in the world (the "1").

K-1 rules allow fighters from many different disciplines to compete, and the elaborate production values of K-1 events makes these extravaganzas a veritable feast for the senses. Since its introduction in 1993 under the direction of founder Master Kazuyoshi Ishii, K-1 has become one of the world's fastest-growing sports.

Honor and respect rule in the K-1 arena, combatants draw on their finely-honed skills to deliver the artful punches and kicks that have wowed millions and made K-1 the terrific success that it is. You don't have to be a martial arts aficionado to enjoy K-1: People everywhere enjoy action and excitement, and K-1, the world's premier fighting sport, delivers.
