Rizin Fighting Federation (stylised in all caps and also known asRizin FF) is a Japanesemixed martial arts organization created in 2015 by the formerPride Fighting Championships andDream Stage Entertainment presidentNobuyuki Sakakibara.^[1][2]

Founded to be thespiritual successor of Pride FC,Hero's andDream, Rizin carries much of the philosophy and ambition of its two predecessors: its events are promoted as larger-than-life events with elaborate opening ceremonies and fighter entrances, its matches are fought in aroped ring and it has a ruleset inherited from Pride and Dream. The organization also promotes "Grand Prix",single-elimination tournaments where fighters have to fight multiple opponents in the same night.^[3][4] Rizin is considered Japan's top MMA promotion.^[5]

Besides MMA, Rizin events also occasionally contain othercombat sport bouts, the promotion promotedkickboxing — with two "Grand Prix" tournaments in 2017^[6] and 2021.^[7] —submission grappling,boxing^[8] andbare-knuckle boxing matches.^[9]

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".^[10]

In 1997,Pride Fighting Championships was founded in Japan, promoted byDream Stage Entertainment. The organization quickly rose up to become the world's most popularMMA promotion and helped to popularize the sport in Japan and in the world. Pride differentiated itself from theUFC with its focus on spectacle and entertainment, as well a more permissive ruleset.^[11] By 2007, a scandal alleging its ties to theyakuza caused a financial decline that led to the promotion folding. Dream Stage Entertainment was bought byZuffa—UFC's holding company—which initially promised to keep the event running. However, Zuffa would lay off most of Pride's staff with several Pride fighters moving to the UFC.^[11]

After Pride folded, most of DSE's former staff, fighters and executives joinedFighting and Entertainment Group, the promoters ofK-1, to organize a successor, which became known asDream.^[12] However, FEG would have its own financial issues and went bankrupt in 2012. As a result, Dream became defunct.^[13]

Three years after Dream folded, rumors began circulating that Pride and Dream founderNobuyuki Sakakibara would return to the industry after an interview withBellator MMA PresidentScott Coker was released.^[14] On September 19, 2015, duringBellator MMA & Glory: Dynamite 1, it was announced that Sakakibara had signed formerPride Heavyweight ChampionFedor Emelianenko to headline a New Year's Eve Show inTokyo for his new MMA promotion.^[15] Sakakibara held a press conference on October 8, 2015, withNobuhiko Takada and other former Pride FC employees to formally announce the launch of "Rizin Fighting Federation".^[16] Initial signees includedKazushi Sakuraba,Shinya Aoki, as well as female competitorsGabi Garcia andRena Kubota.^[17]

A Grand Prix tournament was announced (held at 100 kg or roughly 220 lbs), with champions and competitors from Bellator,KSW,Jungle Fight,^[18]BAMMA, andKing of Kings. Most notably,King Mo was announced to represent Bellator in the tournament.^[19] The 8-man bracket was officially finalized on November 30, 2015, with other bouts also being announced shortly thereafter.^{[20][21][22][23]}Kron Gracie (whose fatherRickson competed at the inaugural PRIDE event) was announced to participate against Asen Yamamoto.^[24] Amongst the veterans in the Japanese scene,Tsuyoshi Kosaka would faceJames Thompson,^[25] andAkebono Tarō would faceBob Sapp.^[26]

Initial plans were to do at least four events per year, as opposed to the more frequent scheduling of other promotions, in order to build up the excitement and anticipation.^[27] Rizin's presentation is modeled after major sporting events, such as theUEFA Champions League andFIFA World Cup.^[28]

In 2018, it was announced that the main event for the traditional New Year's Eve card (Rizin 14) was going to be a boxing match betweenFloyd Mayweather Jr. and undefeated Japanese kickboxerTenshin Nasukawa.^[29] The match ended up with Nasukawa knocked out two minutes into the first round.^[30]

Rizin Trigger 1st, on November 11, 2021, would be Rizin's first event in which matches would take place inside a cage, instead of the traditional roped ring.^[31]

In Summer 2022, Sakakibara would produce theTenshin Nasukawa vs. Takeru PPV broadcast (known as "THE MATCH 2022"), with the broadcast using Rizin's on-air graphics and visual presentation.^[32] Mayweather would return to Rizin that September to co-promote (via The Money Team) and headline the inauguralSuper Rizin card.^[33][34]

On December 31, 2022, as the traditional New Year's Eve event, Rizin hosted a crossoverBellator vs Rizin card withBellator MMA as part ofRizin 40.^[35] The card saw fighters from each promotion fight each other.^[36] The card saw Bellator MMA fighters Gadzhi Rabadanov, former championsA.J. McKee,Juan Archuleta andKyoji Horiguchi, and current championPatricio Freire, fighting against Rizin representatives Koji Takeda, Soo Chul Kim,Hiromasa Ougikubo and championsKleber Koike Erbst andRoberto de Souza. All five Bellator representatives would win their matches in a clean sweep.^[37] During the event, formerboxing world championManny Pacquiao made a public announcement that he had signed with Rizin for a boxing exhibition match against a yet-unannounced opponent.^[38]

During theSuper Rizin 2 card on July 30, 2023, the promotion announced their first international event,Rizin Landmark 7, to take place in Azerbaijan on November 4.^[39] It will also be the first major MMA event to take place in the country.^[40]

In June 2024, Rizin announced a partnership withBare Knuckle Fighting Championship (BKFC), which both companies would allow talent fight in each other's organizations in bareknuckle bouts. AtSuper Rizin 3 on July 28, 2024, Charisa Sigal, Tai Emery, Takaki Soya, andJohn Dodson all fought in bare-knucking bouts on the undercard.^[41][9]

Rizin's inaugural event was broadcast in North America onSpike TV.^[42] Other broadcasters have includedSKY Perfect JSAT Corporation,Fuji Television,Fox Sports Brazil,Kix andMatch TV.^[43] From 2017 to 2020, Rizin events have been streaming onFITE TV in North America and Europe.^[44] Rizin 26 to Rizin 37 would stream onLIVENow in Europe and North America.^[45]

In 2022, due to several controversies, Rizin would be dropped by Fuji by May of that year.^[46][47] Rizin would since begin broadcasting on events via PPV on their streaming service, RIZIN STREAM PASS, and various other streaming platforms in Japan.^[48]

Starting withSuper Rizin & Rizin 38 in 2022,^[49][50] Integrated Sports would produce English-language PPVs of Rizin events for FITE.^[51]

In February 2024, Rizin announced the launch of a new international service,RIZIN.tv. From March, the service will be subscription-based, and will include past events.^[52]

The rules in Rizin FF have been adopted from Pride FC with some slight modifications over the years. Matches are three rounds in length. Prior to May 2018, the first round of men's matches spanned 10 minutes, while the final two rounds lasted five minutes each. Since then matches have been three rounds of five minutes each. Victory can be attained byknockout,submission,technical knockout byreferee stoppage, or by judges' decision.

All strikes, throws and chokes are permitted, with the exception ofheadbutts and strikes to the back of the head,medulla oblongata, spinal cord or genitals.^[53]Soccer kicks,knees andstomps to grounded opponents are also permitted. However, if there is a weight discrepancy of 15 kg (33 lb) or more, the lighter fighter is allowed to choose if such ground attacks are permitted.^[53] Unlike Pride, Rizin allows the use ofelbow strikes, including the12–6 elbow.^[54]

Fights are judged on the following criteria:^[53]

• Damage: when assessing damage, both striking and grappling are given the same weight. The judges will place value on the extent to which the effective striking or grappling 'influences the match' - in other words, whether there was such damage/advantage to the fighter which would have led to the fight being ended by the opponent tapping out or being knocked out.
• Aggressiveness: the judges will consider which fighter was more effective in delivering attacks which may end the fight in a finish. Note this element does not take into consideration the actual impact of damage caused by the fighter's strikes, throws or submission. Rather, the judges will place value on whether fighters were aggressive and proactive in their approach during the fight.
• Generalship: the judges will consider which fighter was more effective in dominating the pace, place and position of the fight. Judges will also consider the amount of time spent in a ground position or the standing position.

Although not outlined in the Rizin rules, scorecards published on the JMOC website suggest that damage, aggressiveness and generalship are scored 50, 30 and 20 points respectively. Where the fighter has not fulfilled the element, they are given a score of zero - there are no in-betweens.^[54]

Rizin kickboxing matches are three rounds of three minutes each. Victory can be attained by knockout, technical knockout by referee stoppage, or by judges' decision. If the match goes the distance, a 10-point system is used to judge.^[53] Threeknockdowns in a single round will result in a technical knockout.^[53] All forms of elbow strikes are illegal.^[53]
