Rizin Fighting Federation

Rizin Fighting Federation (stylised in all caps and also known as Rizin FF) is a Japanese mixed martial arts organization created in 2015 by the former Pride Fighting Championships and Dream Stage Entertainment president Nobuyuki Sakakibara. Founded to be the spiritual successor of Pride FC, Hero's and Dream, Rizin carries much of the philosophy and ambition of its predecessors: its events are promoted as larger-than-life events with elaborate opening ceremonies and fighter entrances, its matches are fought in a roped ring and it has a ruleset inherited from Pride and Dream.
