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. Rizin also revived Pride's tradition of holding major events on New Year's Eve, beginning with its inaugural event in 2015, and has continued to hold New Year's Eve cards in subsequent years. The organization also promotes "Grand Prix", single-elimination tournaments where fighters have to fight multiple opponents in the same night. Rizin is considered Japan's top MMA promotion.

Besides MMA, Rizin events also occasionally contain other combat sport bouts, the promotion promoted kickboxing — with two "Grand Prix" tournaments in 2017 and 2021. — submission grappling, boxing and bare-knuckle boxing matches.

The promotion's name is a combination of "Raijin", the Japanese god of lightning; the word "rising", meaning "to prosper and thrive"; and the letter, 'Z', meaning "ultimate".
