Rizin Fighting Federation (Rizin FF) is a Japanese mixed martial arts (MMA) promotion founded in 2015 by Nobuyuki Sakakibara, the former president of Pride Fighting Championships, as a spiritual successor to Pride and Dream. Based in Tokyo, Rizin quickly became Japan’s top MMA organization, known for its spectacle-style events with elaborate fighter entrances and a traditional roped ring rather than a cage. It also features Grand Prix-style tournaments where fighters may face multiple opponents in one night, and occasionally includes kickboxing, submission grappling, and other combat sports bouts on its cards.
Rizin blends high-production entertainment with a ruleset that allows exciting techniques like soccer kicks and stomps under certain conditions, drawing on its Pride-era heritage. Its flagship events — especially the annual New Year’s Eve shows at Saitama Super Arena — showcase top Japanese talent alongside international fighters and co-promotions with organizations like Bellator MMA, helping it maintain a strong presence in global MMA while honoring Japanese fight culture.
