Rizin Fighting Federation
The Rizin Fighting Federation (Rizin FF) is a prominent Japanese mixed martial arts (MMA) promotion company that organizes professional fighting events emphasizing spectacle, grand prix tournaments, and high-stakes bouts, often held in large venues like the Saitama Super Arena.[1][2] Founded in 2015 by Nobuyuki Sakakibara, the former president of the influential Pride Fighting Championships, Rizin was established as a spiritual successor to Pride and the Dream promotion, aiming to revive Japanese MMA's tradition of dramatic, entertainment-focused competitions.[1][3][2] Rizin's inaugural event, Rizin 1, took place on December 31, 2015, featuring notable fighters such as Fedor Emelianenko and Kazushi Sakuraba, and it quickly gained attention for its open-weight grand prix format and crossover appeal.[4][5] The promotion has since hosted annual New Year's Eve extravaganzas, often with multiple title fights and celebrity bouts, such as Floyd Mayweather's exhibition against Tenshin Nasukawa in 2018, solidifying its reputation for blending MMA with broader combat sports entertainment.[6][2] Under Sakakibara's leadership, Rizin has expanded internationally, co-promoting events with organizations like Bellator MMA, and holding cards in Japan and South Korea as of 2025, while maintaining a core focus on Japanese talent development.[7][8] A defining feature of Rizin is its ruleset, adapted from Pride FC with modifications, including three five-minute rounds for non-title fights (and titles), allowance of soccer kicks and stomps to a grounded opponent.[9][3] The promotion prioritizes aggressiveness and damage in judging, often without strict weight classes in grand prix events, which has led to memorable heavyweight clashes and upsets.[9][10] Rizin has produced multiple champions across divisions like bantamweight and featherweight, and it continues to influence global MMA through talent exchanges and innovative event formats.[11][7]History
Formation and launch (2015)
The Rizin Fighting Federation was established in 2015 by Nobuyuki Sakakibara, the former president and co-founder of Pride Fighting Championships, as a direct successor to Pride with a focus on recapturing the spectacle, drama, and grandeur of large-scale Japanese MMA events.[12] Sakakibara, who had previously led Pride to become a global phenomenon before its 2007 dissolution, aimed to revive the promotion's emphasis on entertainment-driven bouts, international talent, and cultural resonance in Japan, positioning Rizin as a platform for high-stakes grand prix tournaments and exhibition matches.[1] Rizin's debut came with the inaugural events in late 2015, including the Rizin Fighting World Grand Prix 2015: IZA on December 31 at Saitama Super Arena in Saitama, Japan, drawing an announced attendance of 18,365 fans and marking a bold entry into the post-Pride MMA landscape.[13] The card highlighted Rizin's flair for unconventional matchups, such as the exhibition bout between Pride icon Kazushi Sakuraba and Shinya Aoki on December 29, underscoring the promotion's commitment to theatrical elements reminiscent of Pride's heyday.[14] The event achieved a peak Japanese TV rating of 7.3% on Fuji TV, reflecting its immediate draw on New Year's Eve programming and signaling a resurgence of MMA interest in Japan after years of dormancy.[13] At launch, Rizin differentiated itself from mainstream promotions like the UFC by adopting a rule set that permitted soccer kicks, stomps, and knees to the head of grounded opponents, fostering a more aggressive and unpredictable fighting style akin to Pride's regulations. These allowances, combined with no weight limits on strikes and the use of a hexagonal ring, were designed to encourage finishing fights and enhance viewer excitement, quickly establishing Rizin's identity as a spectacle-oriented alternative in global MMA.[12] The inaugural event's success in attendance and ratings underscored Rizin's cultural impact, reigniting national enthusiasm for homegrown MMA promotions and setting the stage for its growth.[13]Early development and key events (2016–2017)
Following the inaugural events in late 2015, Rizin Fighting Federation solidified its presence in 2016 with a series of high-profile cards that emphasized spectacle and veteran matchups, drawing on Pride FC's legacy of open-weight tournaments. Rizin 1 on April 17 in Nagoya featured bouts like the tag-team grappling match between Kazushi Sakuraba and Hideo Tokoro against Wanderlei Silva and Kiyoshi Tamura, which ended in a draw, and the debut of rising star Kyoji Horiguchi, who submitted Vaughn Lee, helping to build momentum with approximately 7,300 attendees. The promotion then launched its first major tournament at Rizin 2 on September 25 in Saitama Super Arena, the World Grand Prix 2016 opening round, where 16 heavyweights competed in an open-weight format, highlighted by Mirko "Cro Cop" Filipovic's Achilles tendon hold submission of Wanderlei Silva in a highly anticipated rematch from their 2006 Pride encounter.[15] Subsequent events included Rizin 3 on November 5 in Fukuoka, showcasing international talent like Jussier Formiga's win over Kai Asakura, and Rizin 4 on December 30 in Saitama, which served as the Grand Prix quarterfinals and semifinals. The 2016 open-weight Grand Prix culminated on December 31 at Saitama Super Arena, where Filipovic claimed the title with back-to-back first-round knockouts, defeating Anthony "Lionheart" Smith in the semifinals and Amir Aliakbari in the final via strikes, earning a $1 million prize and marking a triumphant return for the 42-year-old Croatian after his 2015 retirement.[16] This tournament format, with its single-night eliminations and no weight restrictions, drew criticism for safety concerns but boosted viewership, with the event broadcast live on Japanese television and streamed internationally. However, the planned rematch between Silva and Filipovic fell through when Silva withdrew from the December 29 quarterfinal due to a back injury sustained in training, prompting heated public exchanges where Filipovic accused Silva of fear and unreliability, escalating tensions and underscoring the promotion's challenges with fighter availability.[17] In 2017, Rizin shifted toward structured weight classes to attract broader talent pools and address open-weight risks, introducing the Bantamweight Grand Prix as its centerpiece tournament while maintaining Pride-inspired rules like permitted soccer kicks to grounded opponents despite international feedback on their brutality following high-profile uses in 2016 events. No major rule alterations occurred that year, but officials clarified the "grounded" definition—requiring both hands and a knee on the canvas—to mitigate excessive ground strikes after incidents like those in the 2016 Grand Prix drew scrutiny from athletic commissions abroad.[18] The year opened with Rizin 5 on April 16 in Yokohama Arena, featuring veteran Tatsuya Kawajiri's loss to Anthony Birchak and a kickboxing showcase by Tenshin Nasukawa, drawing around 12,000 fans and highlighting Rizin's blend of MMA and striking rulesets. Rizin 6 on June 10 in Nagoya included notable wins for Issei Tamura over Satoru Kitaoka, while Rizin 11 on July 29 in Saitama saw Jiri Prochazka's first-round knockout victory over Bruno Cappelozza in the latter's promotional debut. The Bantamweight Grand Prix opening rounds spanned Rizin 8 on July 30 in Saitama, where Kyoji Horiguchi advanced via first-round TKO over Hideo Tokoro, and the October 15 event in Fukuoka (Rizin 7), building to the December finals.[19] The 2017 Bantamweight Grand Prix semifinals and finals on December 29-31 in Saitama showcased intense competition, with Horiguchi defeating Shintaro Ishiwatari via second-round submission in the final to win the $500,000 prize after earlier victories over Darryle Owen and Ishiwatari, solidifying his status as a top draw. Featured non-tournament bouts included Ulka Sasaki's unanimous decision win over Manel Kape in a bantamweight clash on December 31, demonstrating Rizin's growing emphasis on ranked divisions beyond open-weight spectacles. Rizin 8 through the year-end events averaged 20,000 attendees per major card, supported by financial backing from Japanese broadcaster WOWOW for domestic telecasts and international streaming deals with platforms like UFC Fight Pass, which provided global access starting in 2016 and helped offset production costs amid sponsorships from brands like Asics and Japanese energy firms.[20] These developments marked Rizin's transition from novelty-driven events to a sustainable promotion, though fighter injuries—like those plaguing the Grand Prix brackets—remained a persistent challenge.[21]Growth and international expansion (2018–2025)
Following the success of its early Grand Prix tournaments, Rizin Fighting Federation transitioned toward establishing permanent championships to provide ongoing structure and prestige to its divisions. The inaugural Rizin Bantamweight Championship was created in December 2018, with Kyoji Horiguchi defeating Darrion Caldwell via guillotine choke submission at Rizin 14 to claim the title in a crossover bout co-promoted with Bellator MMA.[22] Horiguchi, who had previously won the 2017 Bantamweight Grand Prix, defended the belt in 2019 before vacating it later that year to focus on opportunities in Bellator, marking the beginning of a more stable title system amid Rizin's maturation.[23] This shift to permanent titles continued with additional divisions, including the Flyweight Championship introduced in December 2023, where Horiguchi again emerged victorious by submitting Makoto Shinryu via rear-naked choke at Rizin 45 to become the first champion.[24] These developments helped solidify Rizin's competitive landscape, attracting top talent and fostering rivalries that extended beyond one-off tournaments, with Horiguchi's defenses exemplifying the promotion's emphasis on high-level matchmaking. Rizin's international expansion gained momentum in the late 2010s, highlighted by crossover events with Bellator that featured Rizin title fights on American soil, such as Horiguchi's 2019 defense preparations tied to U.S.-based bouts.[25] Efforts to host full events abroad culminated in the Rizin World Series in Korea on May 31, 2025, at Paradise City in Incheon, South Korea, marking the promotion's first standalone card outside Japan and drawing a diverse lineup of regional and international fighters.[26] Attendance at major events reflected growing global interest, with Rizin 45 in 2023 selling out Saitama Super Arena to 23,013 fans, while viewership trends showed steady increases, including over 420,000 PPV buys for Super Rizin 3 earlier that year. By 2025, events like Otoko Matsuri at Tokyo Dome attracted 42,706 attendees, underscoring Rizin's expanding footprint.[27] The COVID-19 pandemic significantly disrupted Rizin's operations from 2020 to 2021, limiting international fighter imports and leading to hybrid formats with reduced crowds and domestic-only rosters to comply with Japanese health protocols.[28] Events like Rizin 22 in August 2020 proceeded with limited capacity at Marine Messe Fukuoka, focusing on local talent amid travel restrictions that halted cross-promotional appearances. Recovery accelerated post-2021, with full-capacity mega-events returning; Rizin 45 in December 2023 exemplified this rebound, hosting 17 bouts including multiple title fights and drawing record domestic viewership on Fuji TV.[24] In 2025, Rizin marked further milestones with Rizin 50 on March 30 at Anabuki Arena Kagawa, where Naoki Inoue defended the Bantamweight Championship via split decision against Yuki Motoya in the main event.[29] Otoko Matsuri followed on May 4 at Tokyo Dome, featuring 19 fights across MMA and kickboxing, including featherweight title action and heavyweight Grand Prix quarterfinals, solidifying its status as a premier annual spectacle.[30] The promotion announced the 2025 Flyweight Grand Prix in June, an eight-man tournament starting July 27 at Super Rizin 4 to crown a new champion following Horiguchi's departure to the UFC, with participants including Jose Torres and Hiromasa Ougikubo.[31] Following Super Rizin 4, Rizin continued with Rizin 51 on September 28 in Nagoya, featuring Flyweight Grand Prix semifinals and reserve matches, and Rizin Landmark 12 on November 3 in Kobe, which included title defenses and international bouts. In November 2025, Rizin announced the Super Powerhouse Festival for December 31 at Saitama Super Arena, headlined by six title fights, including Bellator lightweight champion Ryan Bader's promotional debut.[32] These initiatives, amid a competitive global MMA landscape, affirm Rizin's enduring relevance through innovative formats and talent development.[33]Organization and management
Founders and executive leadership
Nobuyuki Sakakibara serves as the founder and CEO of the Rizin Fighting Federation, established in 2015 as a spiritual successor to the Pride Fighting Championships and Dream Stage Entertainment promotions.[1] Sakakibara co-founded Pride FC in the late 1990s, where he rose to president, overseeing its growth into a global MMA powerhouse before its sale to Zuffa in 2007 and subsequent closure.[1] Following Pride's end, he launched Dream in 2008, managing it until 2012, before shifting focus to Rizin to revive Japanese MMA's spectacle-driven style.[2] Under Sakakibara's leadership, Rizin operates as a federation model, partnering with established Japanese promotions such as Deep, Shooto, and Pancrase to curate events, emphasizing collaborative decision-making for fight card assembly and fighter selection.[1] Key executives include matchmaker Shingo Kashiwagi, responsible for matchmaking strategies that prioritize exciting, marketable bouts over strict rankings.[1][34] In April 2025, Michael Craven, formerly of New Japan Pro-Wrestling, joined the executive team.[35] Sakakibara maintains central authority on strategic decisions, including event planning and high-profile signings, fostering a board-like structure through these partnerships rather than a traditional corporate hierarchy. Sakakibara's vision positions Rizin as a distinct entertainment entity, blending MMA with theatrical elements like New Year's Eve spectacles and co-promotions to differentiate from UFC's model, aiming to build a global audience through narrative-driven content and diverse combat formats.[2][1] Leadership has remained stable through 2025, with Sakakibara actively leading press conferences and negotiations, such as those for the Rizin World Grand Prix, ensuring continuity in operations amid international expansions.[36]Affiliated promotions and partnerships
Rizin Fighting Federation has forged a significant partnership with Bellator MMA, enabling fighter crossovers and co-promoted events that enhance talent exchange between the promotions. This collaboration gained momentum in 2019, highlighted by the participation of fighters like Kyoji Horiguchi, who competed in both organizations following his departure from UFC.[7] Co-promoted cards, such as the 2022 New Year's Eve event at Saitama Super Arena, featured Bellator athletes competing under Rizin rules, culminating in a 5-0 victory sweep for Bellator.[37] Subsequent events in 2023, including Super Rizin 2 and Bellator X Rizin, further solidified this alliance, with Bellator president Scott Coker emphasizing its role in revitalizing Japanese MMA.[38] Even after PFL's 2023 acquisition of Bellator, Rizin executives expressed intent to continue these cooperative efforts.[39] Within Japan, Rizin maintains close ties to longstanding promotions like Pancrase and Shooto, functioning as a premier stage for their emerging talents and fostering a domestic feeder system. Fighters from these organizations, such as former Shooto champion Kyoji Horiguchi and Pancrase competitors like Taichi Nakajima, have transitioned to Rizin bouts, promoting cross-promotional growth without direct rivalry.[34] Rizin CEO Nobuyuki Sakakibara has underscored this symbiotic relationship, noting that the promotion was designed to complement rather than compete with established Japanese entities like Pancrase and Shooto.[40] This integration has allowed Rizin to draw from a deep pool of regional talent, enhancing event quality through joint exposure opportunities. In a push for international expansion, Rizin hosted its inaugural event in South Korea with the RIZIN World Series in Korea on May 31, 2025, at Paradise City in Incheon, structured around a Japan-versus-Korea theme to build regional partnerships.[41] The card featured matchups pitting Japanese fighters against Korean counterparts, aiming to cultivate alliances with local MMA scenes and attract cross-border talent.[42] This debut marked Rizin's strategic entry into the Korean market, leveraging the event's success to explore further collaborations.[26] Rizin has also secured key sponsorships and broadcasting partnerships to support its operations, including a title sponsorship from SAMURAI ENERGY for multiple 2023 events.[36] The promotion's official streaming service, RIZIN.tv, provides global access to live PPV events and archives, broadening its audience reach.[43] In June 2024, Rizin announced a partnership with Bare Knuckle Fighting Championship (BKFC) for fighter sharing and potential co-promoted events, expanding into hybrid combat sports collaborations.[44] To ensure integrity, Rizin aligns its anti-doping policies with World Anti-Doping Agency (WADA) standards, utilizing WADA-accredited testing for fighters, as demonstrated by the 2023 positive steroid result for Minoru Kimura following Rizin 43.[45] Since its inception, Rizin has committed to strict drug controls, including contract clauses for positive tests, to maintain a clean competitive environment.[46]Rules and regulations
Unified rules framework
The Rizin Fighting Federation employs a hybrid ruleset that draws inspiration from the Pride Fighting Championships and contemporary mixed martial arts standards, overseen by the Japan MMA Officials Committee (JMOC) to ensure consistency and fairness across events.[9][47] This framework prioritizes athlete safety through strict prohibitions on fouls such as eye gouges, hair pulling, and other unsportsmanlike conduct, while mandating comprehensive medical evaluations prior to bouts, including blood tests and physical assessments to confirm fighter fitness.[9][48] Event protocols emphasize controlled aggression and recovery, incorporating standing restarts after prolonged ground inactivity to promote dynamic action, alongside measures to curb extreme weight-cutting practices that could compromise health, such as monitored rehydration periods and penalties for significant weight misses.[9] Since its inception in 2015, the framework has evolved under JMOC guidance—established in 2017 to standardize Japanese MMA regulations—introducing updates like the legalization of certain strikes and the implementation of video review for controversial decisions by 2022, enhancing accountability and precision in officiating.[47][48] This alignment with JMOC's oversight ensures compliance with broader Japanese combat sports licensing and insurance standards, fostering a secure environment for all combatants.[47]MMA-specific rules and judging
Rizin Fighting Federation's MMA rules diverge from the standard Unified Rules of Mixed Martial Arts by permitting certain strikes to grounded opponents that are prohibited elsewhere, such as soccer kicks, stomps, knees to the head, and 12-6 elbow strikes. These techniques are allowed provided the opponent is considered grounded, defined similarly to legacy promotions like Pride FC, where any body part other than the soles of the feet touching the canvas qualifies the fighter as grounded, enabling the standing fighter to target the head without restriction. This contrasts sharply with the Unified Rules, which ban such strikes to a grounded opponent to prioritize safety and limit potential for excessive damage.[9][49] Judging in Rizin MMA employs a holistic scoring system for the entire fight rather than round-by-round evaluation, overseen by the Japan MMA Officials Committee (JMOC). Criteria emphasize damage (50% weight), assessing the cumulative impact of both striking and grappling exchanges equally; aggressiveness (30% weight), rewarding fighters who press the action with potential fight-ending intent; and generalship (20% weight), favoring control over pace, position, and overall fight dominance. This approach prioritizes effective striking, sustained aggression, and grappling control to reward dynamic performances over mere accumulation of minor damage, differing from the damage-centric focus in many Western promotions. While not using the traditional 10-point must system, scores reflect these weighted factors to determine the winner, with draws possible if no clear superiority is established.[9] To promote continuous action, Rizin referees enforce stand-up policies more proactively than in Unified Rules bouts, intervening to restart fighters on their feet if grappling exchanges stall without significant advancement, such as prolonged inert top control or mutual resting on the ground. A fighter is deemed grounded only when a knee or other non-foot body part contacts the mat, allowing strikes in transitional positions; otherwise, the referee may stand them up to prevent stagnation. This policy underscores Rizin's emphasis on spectacle and forward momentum in MMA contests.[9]Kickboxing rules and variations
Rizin's kickboxing bouts adhere to a stand-up-only format that prohibits takedowns and any ground fighting, emphasizing pure striking exchanges while allowing limited clinching for offensive purposes.[50] Fighters may utilize punches, kicks to the body and head, knees, and elbows during clinches, with referees intervening to break prolonged holds that stall the action.[51] These matches consist of three rounds lasting three minutes each, followed by one-minute rest periods, though championship contests may extend to five rounds.[50] Scoring in Rizin kickboxing employs a 10-point must system across three judges, prioritizing the effectiveness of clean strikes—particularly damaging leg kicks that impair mobility—alongside overall aggression and control of the ring space.[50] Deductions are applied for infractions like excessive clinching, holding, or illegal strikes, which can result in point reductions or disqualification if repeated.[50] This framework parallels aspects of Rizin's MMA judging in its focus on impactful offense but excludes grappling metrics to maintain striking purity.[50] Kickboxing has been a staple on Rizin's main cards since 2016, often featuring high-profile title fights that showcase international talent under these regulations.[36]Divisions and weight classes
Men's MMA divisions
The Rizin Fighting Federation employs a series of men's MMA weight classes designed to promote competitive balance and high-paced action, drawing from international standards while emphasizing divisions up to heavyweight. These classes include flyweight up to 57 kg (125.7 lb), bantamweight up to 61 kg (134.5 lb), featherweight up to 66 kg (145.5 lb), lightweight up to 71 kg (156.5 lb), welterweight up to 77 kg (169.8 lb), middleweight up to 85 kg (187.4 lb), light heavyweight up to 93 kg (205.0 lb), and heavyweight up to 120 kg (264.6 lb). Openweight bouts, with no upper limit, are frequently used for grand prix tournaments to showcase unrestricted matchups among top fighters.[52] Weigh-ins for Rizin MMA events typically occur the day before the event, allowing fighters a rehydration period. This procedure contrasts with many Western promotions by minimizing extreme weight cuts and enabling fighters to compete closer to their natural walking weight.[53] The light heavyweight division was formally established in 2019, coinciding with the inaugural championship bout at Rizin 15 between Jiri Prochazka and Muhammed Lawal, marking a key expansion to accommodate skilled competitors in the 205 lb class for title contention.[52] Rizin has expanded to include a heavyweight division with an inaugural title bout scheduled for December 31, 2025, while maintaining a core focus on lighter divisions to foster faster, more technical fights aligned with the promotion's entertainment-focused ethos.[54]Women's MMA divisions
The Rizin Fighting Federation established its women's MMA program with the introduction of the Super Atomweight division in 2017, capped at 49 kg (108 lb), through the inaugural Women's Super Atomweight Grand Prix held across multiple events that year.[55] This class quickly became the primary focus for female competitors, serving as the foundation for title bouts and ongoing development within the promotion, alongside an Atomweight division up to 47 kg (103.6 lb). Rizin places significant emphasis on nurturing Japanese talent in this division, aligning with the promotion's broader mission to bolster domestic MMA growth amid Japan's evolving combat sports landscape.[56] Weigh-in procedures and safety protocols for women mirror those applied to men's divisions, including standard hydration testing.[57] In a limited expansion, Rizin has tested the Strawweight division at 52 kg (115 lb) through trial bouts featured in events from 2023 to 2025, such as non-title matchups that showcased emerging prospects. As of November 2025, no formal Strawweight championship has been established. By 2025, women's bouts have progressed from sporadic Grand Prix formats to consistent main card placements, with multiple Super Atomweight defenses integrated into major annual cards like the New Year's Eve extravaganza.[58][54]Kickboxing divisions
Rizin's kickboxing divisions generally mirror the weight classes used in its MMA bouts, spanning from flyweight (up to 57 kg) to heavyweight (up to 120 kg) for male competitors, with specific bout weights set for each match to align with fighter profiles and event needs.[59] Openweight formats without upper limits are commonly employed for tournament-style Grand Prix events, allowing for high-profile clashes across size differences.[60] These divisions emphasize stand-up striking under Rizin Kickboxing rules, distinct from the grappling-inclusive MMA structure.[53] The promotion does not maintain a dedicated women's kickboxing division, though isolated super fights have occasionally featured at lower weights such as super atomweight (up to 49 kg).[61] Examples include bouts at 53 kg, highlighting potential for future expansion but limited to special matchups rather than regular competition.[62] Weigh-ins for kickboxing matches occur the day prior to events, typically in the late evening or midnight hours, which facilitates complete rehydration and recovery to maximize fighters' power and endurance in striking exchanges.[63] This procedure supports the promotion's focus on explosive, high-impact kickboxing performances.[64] Kickboxing has been integral to Rizin programming since the inaugural event in late 2015, predominantly appearing in Grand Prix tournaments and undercard slots to complement the MMA main attractions.[65] By 2016, it became a recurring format for showcasing domestic and international strikers in non-title scenarios.[66]Broadcasting and media
Domestic Japanese coverage
Rizin's New Year's Eve specials are primarily broadcast on Fuji Television, a major free-to-air network in Japan that has aired the promotion's flagship end-of-year events since its inception. These broadcasts have achieved significant audience reach, with the 2016 Grand Prix leg drawing over 10 million viewers, marking one of the promotion's peak performances in domestic television metrics.[21] In subsequent years, ratings for these specials typically hovered around 5-7.5%, translating to millions of households tuned in during prime time, though competition from traditional programming like music festivals often places Rizin in the lower ranks among networks.[67] For regular events, Rizin partners with Sky Perfect TV, Japan's leading satellite broadcaster, offering pay-per-view access through its platform since the promotion's early days.[68] This arrangement provides comprehensive coverage for subscribers, including live feeds and replays, complementing the high-profile Fuji TV slots. Additionally, AbemaTV, a digital streaming service targeting younger audiences, integrates Rizin content through non-exclusive deals, streaming select events, highlights, and replays to expand accessibility beyond traditional TV.[69] This partnership has helped boost engagement among demographics under 35, who prefer on-demand viewing options.[70] In 2025, viewership trends reflect a shift toward hybrid TV-streaming models, with domestic streams for major cards showing steady growth amid increased digital adoption.International distribution and streaming
Rizin Fighting Federation has expanded its international footprint by leveraging digital streaming platforms to deliver events to audiences outside Japan, focusing on pay-per-view models and subscription services for global accessibility. From 2019 onward, Rizin events were distributed internationally via pay-per-view on FITE TV, allowing fans in North America and Europe to purchase live streams and replays of major cards.[71] In February 2024, the promotion launched RIZIN.tv as its dedicated international streaming service, replacing prior partnerships and offering worldwide access to live pay-per-view events along with an extensive archive of past fights.[72] The platform operates on a subscription model, with monthly and annual tiers that include English commentary for select events, enabling fans to build personalized watchlists and resubscribe easily after any hiatus.[73] To enhance entry-level engagement, Rizin streams preliminary bouts for free on its official YouTube channel, drawing in viewers before directing them to paid main cards on RIZIN.tv. In a key move for Asian expansion, Rizin partnered with local broadcaster SOOP TV to air the 2025 World Series in Korea for free domestically, featuring Korean commentary and highlighting matchups like Ki Won Bin vs. Roberto Satoshi to boost regional viewership.[74] This initiative marked Rizin's second international event and aimed to capitalize on growing interest in MMA across the continent.Events and formats
Annual event structure and traditions
Rizin Fighting Federation has established a tradition of hosting its flagship New Year's Eve event at Saitama Super Arena annually since its inaugural show on December 31, 2015, which reignited Japan's long-standing custom of major combat sports spectacles to close out the year.[75] These events typically feature high-profile title fights alongside celebrity exhibition bouts, such as the 2018 matchup between Floyd Mayweather and kickboxer Tenshin Nasukawa, drawing massive crowds and emphasizing entertainment value.[76] The 2025 edition, scheduled for December 31 at the same venue, continues this pattern with multiple championship contests.[77] The promotion structures its calendar around quarterly mega-events, including the recurring Landmark series, which hosts competitive cards in various Japanese locales, such as Landmark 11 in June and Landmark 12 in Kobe in November 2025.[78] Seasonal Grand Prix tournaments form another key pillar, with single-elimination formats spanning multiple events; for instance, the 2025 Flyweight World Grand Prix began its first round on July 27 at Super Rizin 4, while a Heavyweight Grand Prix kicked off in May.[31] By 2025, Rizin conducts approximately 12 events per year, blending regularity with spectacle to maintain fan engagement.[79] Event cards are hybrid in nature, routinely combining MMA bouts with kickboxing matches and occasional exhibitions to create diverse lineups that appeal to a broad audience.[80] Crossovers with other combat disciplines, such as the 2018 signing and debut of former sumo wrestler Ōsunaarashi Kintaro, highlight Rizin's integration of Japanese martial traditions into its programming.[81] Production elements elevate the events into immersive experiences, featuring pyrotechnics, laser shows, extravagant lighting, and live musical performances accompanying fighter entrances, reminiscent of the promotion's Pride FC roots.[82] Ticketing emphasizes premium access, with VIP seats priced up to ¥110,000 and general admission starting at ¥16,500 for major shows, often including benefits like priority entry.[36]List of major events
The Rizin Fighting Federation has organized over 70 events by late 2025, including numbered cards, landmark series, and special festivals, with record attendances surpassing 40,000 spectators at venues such as the Tokyo Dome and Saitama Super Arena.[79][83] Major events are often categorized by type, with Grand Prix tournaments integrated into select numbered cards like Rizin 1 (2015 Heavyweight Grand Prix) and RIZIN Fighting World Grand Prix 2017: Final Round (2017 Bantamweight Grand Prix), highlighting tournament-style competitions alongside standard bouts.[78]| Event Name | Date | Venue | Location | Attendance | Main Event |

Bantamweight Championship history
The Rizin Bantamweight Championship, contested at 61 kg (134 lb), was established in 2018 as part of the promotion's effort to crown division leaders through a mix of direct title bouts and Grand Prix tournaments. The inaugural champion, Kyoji Horiguchi, captured the belt in a high-profile crossover match against Bellator's Darrion Caldwell on December 31, 2018, at Rizin 14, submitting him with a guillotine choke in the first round. This victory marked a notable unification-style bout, pitting Rizin against a major international promotion. Horiguchi made one successful defense, stopping Manel Kape via TKO (doctor stoppage due to cuts) in the third round at Rizin 17 on July 28, 2019. However, an ACL injury forced Horiguchi to vacate the title later that year, creating the first vacancy in the division's short history.[99][22][100] The vacant title was claimed by Manel Kape, who upset top contender Kai Asakura with a second-round TKO (punches) at Rizin 20 on December 31, 2019. Kape's reign was brief, with no defenses, as he vacated the belt in early 2020 amid contract negotiations and injury concerns. Kai Asakura then won the vacant championship against Hiromasa Ogikubo via first-round knockout (soccer kicks) at Rizin 23 on August 10, 2020, beginning a turbulent period for the division marked by frequent changes. Asakura's reign lasted only until December 31, 2020, when Horiguchi reclaimed the title in a rematch at Rizin 26, submitting him with a rear-naked choke in the first round. Horiguchi added one more defense, defeating Ogikubo by unanimous decision at Rizin 28 on March 21, 2021, before vacating the belt in September 2021 to sign an exclusive deal with Bellator MMA while retaining ties to Rizin.[101][102][99] Following Horiguchi's departure, the title was awarded to the winner of the 2021 Bantamweight Grand Prix, with Kai Asakura securing it by defeating Kleber Koike Erbst via second-round TKO (punches) in the tournament final at Rizin 32 on December 31, 2021. Asakura made multiple defenses during this second reign, including a unanimous decision over Yan Diego at Rizin 38 on June 19, 2022, and a TKO against Bruno Silva at Rizin 40 on September 30, 2022, showcasing his striking prowess with nine knockouts across his Rizin career. The belt became vacant again in mid-2023 due to Asakura's inactivity and focus on international opportunities. Juan Archuleta claimed the vacant title with a unanimous decision victory over Hiromasa Ogikubo at Super Rizin 2 on July 30, 2023, but his reign ended abruptly when he was stripped for missing weight by six pounds ahead of his defense at Rizin 45 on December 31, 2023.[103][104] Kai Asakura reclaimed the championship in the ensuing bout at Rizin 45, stopping Archuleta with a body knee in the second round, though no further defenses followed as Asakura vacated the title on June 9, 2024, to sign with the UFC. The promotion then crowned Naoki Inoue as champion after he defeated Kai Asakura's brother, Mikuru Asakura, via second-round submission (kimura) in a tournament final for the vacant belt at Rizin Landmark 9 on September 29, 2024. Inoue, a former UFC fighter known for his grappling, has since made two successful defenses: a split decision over Yuki Motoya at Rizin 50 on March 30, 2025, where he outstruck the challenger despite a strong final round from Motoya; and a unanimous decision against Ryuya Fukuda at Super Rizin 4 on July 27, 2025. These victories highlight Inoue's resilience, with no interim titles introduced during his reign as of November 2025. The division has seen six vacancies in its seven-year history, largely due to injuries, cross-promotional moves, and weight issues, underscoring Rizin's emphasis on Grand Prix formats over traditional linear defenses.[105][106][107]| Champion | Reign Start | Reign End | Defenses | Notes |

Flyweight Championship history
The Rizin Flyweight Championship, contested at a weight limit of 57 kg (125.7 lb), was established in late 2023 to crown the promotion's first titleholder in the division.[111] Kyoji Horiguchi, a former UFC title challenger and two-time Rizin Bantamweight Champion, claimed the inaugural title on December 31, 2023, at Rizin 45 in Saitama, Japan, by submitting Makoto Shinryu via rear-naked choke in the first round. This victory marked Horiguchi's transition to the flyweight class after dominating at bantamweight, solidifying his status as one of Japan's premier mixed martial artists.[100] Horiguchi made his first successful defense on December 31, 2024, at Rizin 49, defeating Nkazimulo Zulu by unanimous decision after five rounds in a closely contested bout that highlighted Horiguchi's striking precision and grappling defense. This defense extended his undefeated streak in Rizin to nine fights and underscored the division's growing competitiveness, with Zulu's aggressive wrestling providing a stern test. However, Horiguchi's reign ended abruptly on March 30, 2025, when he vacated the title upon re-signing with the UFC after eight years away, citing a desire to pursue opportunities in the larger promotion. The vacancy prompted Rizin officials to announce a one-night eight-man Flyweight Grand Prix at Super Rizin 4 on July 27, 2025, to determine the next champion, continuing the promotion's tradition of tournament formats to crown titleholders. The 2025 Flyweight Grand Prix featured a bracket of international talent, with quarterfinal bouts held at Super Rizin 4 in Saitama Super Arena. Key results included Yuki Motoya defeating Hiroya Kondo by unanimous decision, Yuki Ito defeating Nkazimulo Zulu by unanimous decision, Makoto Takahashi submitting Erson Yamamoto via guillotine choke in the second round, and Hiromasa Ougikubo defeating Jose Torres (advancement noted).[33] Semifinals progressed across subsequent events, with Hiromasa Ougikubo advancing by unanimous decision over Alibek Gadzhammatov at Rizin 51 on September 27, 2025, and Yuki Motoya defeating Ryuya Fukuda in the other semifinal. As of November 2025, the division remains without a champion, with the grand prix final between Ougikubo and Motoya scheduled to unify the title on December 31, 2025.| No. | Champion | Date Won | Event | Defenses | Reign Length | Notes |

Featherweight Championship history
The Rizin Fighting Federation introduced the Featherweight Championship (66 kg / 145 lb limit) in 2020, with the inaugural title bout headlining Rizin 25 in Osaka on November 21. Yutaka Saito captured the belt by defeating Mikuru Asakura via unanimous decision after three rounds, marking Saito's third win in the promotion and establishing him as the division's first champion.[112] Saito's reign lasted until October 24, 2021, when he made his sole defense at Rizin 31 in Yokohama against promotional newcomer Juntaro Ushiku. Ushiku, a dual-division champion from DEEP, dethroned Saito via third-round TKO due to a doctor's stoppage from a cut, showcasing his aggressive striking in his Rizin debut. Ushiku, hailing from Japan but with international experience, then defended the title once in a rematch with Saito at Rizin 35 on April 17, 2022, in Tokyo, securing a unanimous decision victory in a closely contested bout that highlighted Saito's resilience.[113][114] Ushiku's second defense opportunity came at Rizin 39 on October 23, 2022, against Brazilian-Japanese submission specialist Kleber Koike Erbst, who entered with a strong grappling pedigree from KSW. Koike Erbst submitted Ushiku via rear-naked choke in the second round, claiming the title and becoming the first international challenger to win the belt in a major event. Koike Erbst's reign was short-lived, as he was stripped of the championship on June 23, 2023, after failing to make weight for a scheduled defense against Chihiro Suzuki at Rizin 43, vacating the title and opening the division to new contenders.[115][116] The vacant title was contested at Rizin Landmark 7 on November 4, 2023, in Kobe, where Japanese kickboxing standout Chihiro Suzuki faced Azerbaijani wrestler Vugar Karamov. Suzuki won via first-round knockout with an upkick, earning the championship in his ninth Rizin appearance and demonstrating the division's integration of striking specialists from other combat sports. Suzuki made his first successful defense at Rizin 46 on April 29, 2024, in Tokyo, stopping veteran Masanori Kanehara via ground-and-pound TKO in the opening round, further solidifying his position with his 15th career first-round finish. However, Suzuki lost the belt in a rematch with Koike Erbst at Rizin DECADE on December 31, 2024, falling via unanimous decision and allowing Koike Erbst to reclaim the title as a two-time champion.[117][118] Koike Erbst's second reign ended abruptly at Rizin: Otoko Matsuri on May 4, 2025, when undefeated Kyrgyz prospect Rajabali Shaidullaev dethroned him via first-round TKO with punches, capturing the title in his fifth Rizin bout and bringing fresh international representation to the division. Shaidullaev, known for his finishing prowess, made his first defense at Rizin 51 on September 28, 2025, in Nagoya, dispatching Russian challenger Viktor Kolesnik via first-round TKO with a right hook and follow-up strikes at 0:33, tying the record for the fastest finish in a Rizin title bout. The featherweight division has occasionally intersected with Rizin's Grand Prix format, as seen in earlier tournaments where contenders like Asakura advanced through bracket-style events before title pursuits, enhancing the belt's prestige through high-stakes, multi-fight nights.[94][119][95]| No. | Champion | Reign Start | Reign End | Defenses | Notes |

Lightweight Championship history
The Rizin Fighting Federation Lightweight Championship, contested at a limit of 71 kg (157 lb), traces its origins to the promotion's 2019 Lightweight Grand Prix tournament, which was won by Azerbaijani fighter Tofiq Musayev after victories over Johnny Case in the semifinals and Patricky Freire in a controversial final at Rizin 20 on December 31, 2019.[121] This tournament victory positioned Musayev for a title opportunity, leading to the formal establishment of the division's championship belt in 2021. Brazilian grappling specialist Roberto "Satoshi" de Souza claimed the inaugural title by submitting Musayev with a rear-naked choke at 1:43 of the first round in the main event of Rizin 28 on June 13, 2021, at Tokyo Dome.[122] De Souza, known for his Brazilian jiu-jitsu expertise, has dominated the division with a series of submission victories in title defenses, underscoring a pattern of Brazilian technical prowess against Japanese striking-oriented contenders. His first defense came against Japanese veteran Yusuke Yachi at Rizin 33 on December 31, 2021, where he secured a triangle armbar submission in the second round at 3:30.[123] He followed with a unanimous decision win over American striker Johnny Case at Rizin 35 on April 17, 2022, marking his second defense. Additional defenses included a first-round TKO (ground and pound) of Luiz Gustavo at 0:21 on September 29, 2024, at Rizin 48, and a unanimous decision over Azerbaijani power-puncher Vugar Karamov at Rizin 49 on December 31, 2024.[124][96] These bouts highlighted ongoing rivalries between Brazilian grapplers like de Souza and international strikers, as well as domestic Japanese challengers seeking to reclaim divisional supremacy. In 2025, the championship landscape saw increased international exposure, with de Souza headlining Rizin World Series in Korea on May 31, 2025, in a non-title bout against local star Won Bin Ki, submitting him via rear-naked choke at 0:50 of the first round to extend his winning streak.[125] The year also featured the return of 2019 Grand Prix finalist Patricky Freire (Pitbull), who debuted against rising Japanese prospect Shunta Nomura at Super Rizin 4 on July 27, 2025, losing by unanimous decision and positioning Nomura as a potential future title threat.[126] De Souza continued his reign with a fifth title defense, submitting Yoshinori Horie via standing rear-naked choke at 1:40 of the first round at Rizin 51 on September 28, 2025.[119][97] As of November 2025, de Souza remains the reigning champion, scheduled to defend against Nomura on December 31, 2025, at Saitama Super Arena.[90]| No. | Champion | Reign Start | Reign End | Defenses | Notes |

Light Heavyweight Championship history
The Rizin Fighting Federation introduced the Light Heavyweight Championship in 2019 to bolster its roster of weight-class titles, with the division set at a 93 kg (205 lb) upper limit. This move aimed to attract top international talent to the 205-pound class, which had previously been highlighted through grand prix tournaments but lacked a dedicated belt. The championship's debut aligned with Rizin's emphasis on high-profile striking exchanges and spectacle-driven bouts typical of the promotion.[127] The inaugural title fight headlined Rizin 15 on April 21, 2019, at Yokohama Arena in Yokohama, Japan, pitting undefeated Czech striker Jiří Procházka against former Bellator contender and 2015 Rizin Heavyweight Grand Prix winner Muhammed "King Mo" Lawal. Procházka, riding a seven-fight win streak that included victories over Vadim Nemkov and Karl Albrektsson, overwhelmed Lawal with relentless pressure and secured the win via knockout with punches at 0:23 of the third round. This victory marked Procházka as the first champion, solidifying his status as a dominant force in the division known for his unorthodox, samurai-inspired fighting style.[128] Procházka made one successful defense later that year at Rizin 20 on December 31, 2019, in Saitama Super Arena, facing former UFC middleweight C.B. Dollaway in a matchup billed as a superfight against a seasoned grappler. The champion ended the bout dramatically with a single right hand knockout at 2:20 of the first round, dropping Dollaway face-first to the canvas in a highlight-reel finish that showcased Procházka's knockout power. This defense highlighted the division's potential for explosive, short-notice stoppages, though it also drew attention to weigh-in challenges, as Dollaway had competed primarily at middleweight and appeared undersized.[129][127] Procházka vacated the title on January 15, 2020, after signing a multi-fight contract with the Ultimate Fighting Championship, where he would go on to capture the UFC light heavyweight crown. The departure of this star contributor led to fewer title opportunities in the division, with Rizin prioritizing other weight classes and grand prix events amid ongoing talent flux. As of November 2025, the championship remains vacant, though the promotion has scheduled a vacant title bout between Ryan Bader and Danny Sabatello for the December 31, 2025, New Year's Eve event, potentially reviving activity in the division.[130][32]Women's Super Atomweight Championship history
The Women's Super Atomweight Championship in Rizin Fighting Federation traces its origins to the 2017 Super Atomweight Grand Prix, a one-night tournament held on December 31, 2017, at Rizin FF 9 in Saitama, Japan, where Kanna Asakura claimed victory by submitting Rena Kubota via rear-naked choke in the final.[131] This tournament established the division's prominence, leading to the inaugural championship bout on December 31, 2018, at Rizin 14, when Ayaka Hamasaki captured the title by submitting Asakura with an armbar in the second round.[132] Hamasaki's reign emphasized grappling prowess, as she defended the belt once against Asakura via split decision on March 21, 2021, at Rizin 27, showcasing the division's competitive depth with rematches rooted in the Grand Prix legacy.[133] Hamasaki lost the title to Seo Hee Ham on December 31, 2019, at Rizin 20, via split decision in a closely contested striking and wrestling battle that highlighted Ham's technical striking edge.[134] Ham, a South Korean veteran, vacated the championship on October 16, 2020, without a defense, paving the way for a vacant title bout on December 31, 2020, at Rizin 26, where Hamasaki reclaimed the belt by submitting Miyuu Yamamoto with a leg scissor choke in the first round.[135] This second reign ended abruptly on December 31, 2021, at Rizin 33, as Seika Izawa, an undefeated prospect, won the title via TKO (elbows and punches) in the second round against Hamasaki.[136] Izawa immediately defended against Hamasaki again on April 17, 2022, at Rizin 35, securing a unanimous decision victory and solidifying her dominance in the division.[136] Izawa's championship era has featured consistent defenses against a mix of Asian and Western challengers, reflecting the division's growing international appeal. On July 30, 2023, at Super Rizin 2, she submitted French fighter Claire Lopez via rear-naked choke in the second round, marking her first official defense and introducing cross-promotional elements through the Bellator collaboration.[137] She followed with a unanimous decision win over Yamamoto on December 30, 2023, at Rizin 45, demonstrating control in grappling exchanges.[138] In 2024, Izawa defeated Asakura via unanimous decision on September 29 at Rizin 48, avenging the Grand Prix roots while maintaining her unbeaten streak.[136] The division expanded its global flavor in 2025 with defenses against Korean challengers, starting with a first-round TKO (punches) over Yu Jin Shin on July 27 at Super Rizin 4, where Izawa's ground-and-pound overwhelmed the newcomer.[139] She retained the title again via unanimous decision against Saori Oshima on November 3, 2025, at Rizin Landmark 12 in Kobe, outgrappling the aggressive striker over three rounds.[140][98] These bouts underscore the championship's evolution from a Japan-centric focus—bolstered by the 2022 Super Atomweight Grand Prix, which Izawa won non-title via split decision over Si Woo Park on December 31 at Rizin 40—to a platform attracting international talent and potential for further weight class expansions within Rizin.[141]| Champion | Reign Start | Reign End | Defenses | Key Notes |
|---|---|---|---|---|
| Ayaka Hamasaki | Dec 31, 2018 | Dec 31, 2019 | 0 | Inaugural champion; won via submission vs. Kanna Asakura.[132] |

Grand Prix tournaments
MMA Grand Prix winners
Rizin Fighting Federation's MMA Grand Prix tournaments feature single-elimination brackets, typically involving eight fighters with reserve participants to fill in case of withdrawals, and emphasize high-stakes, multi-fight nights that test endurance and skill across various weight classes.[79] These events often culminate in title opportunities for the victors and have been a staple since the promotion's inception, drawing top international talent to Japan. By 2025, Rizin has hosted several such MMA Grand Prix tournaments, including the 2017 Women's Atomweight GP won by Kanna Asakura and the 2022 Super Atomweight GP won by Ayaka Hamasaki. The 2025 Flyweight GP is ongoing as of November 2025, with semifinals completed at Rizin 51. Prize structures vary, but major heavyweight or openweight formats have included around $300,000 for the winner, alongside bonuses for semifinalists.[142][143] The inaugural 2015 Heavyweight Grand Prix, limited to fighters under 100 kg, was won by Muhammed "King Mo" Lawal, who defeated Jiri Prochazka in the final after earlier victories in the one-night, eight-man bracket.[144] In 2016, the Openweight Grand Prix saw Mirko "Cro Cop" Filipovic claim the title with two first-round knockouts on the final night, defeating Kaido Hoovelson in the semifinals and Amir Aliakbari in the championship bout.[16] Subsequent tournaments expanded to other divisions, including the 2017 Bantamweight Grand Prix won by Kyoji Horiguchi via three stoppages over two days, and the 2019 Lightweight Grand Prix captured by Tofiq Musayev, who secured back-to-back wins against Johnny Case and Patricky "Pitbull" Freire on New Year's Eve.[145] More recently, the 2025 Heavyweight Grand Prix at Rizin 51 was dominated by Alexander Soldatkin, who outpointed Marek Samociuk in the final after navigating the bracket, earning him a prominent position in the division and potential title contention.[146][119]| Year | Weight Class | Winner | Final Opponent | Event |
|---|---|---|---|---|
| 2015 | Heavyweight (under 100 kg) | Muhammed Lawal | Jiri Prochazka | Rizin Fighting World Grand Prix 2015 |
| 2016 | Openweight | Mirko Filipovic | Amir Aliakbari | Rizin Fighting World Grand Prix 2016 |
| 2017 | Bantamweight | Kyoji Horiguchi | Shintaro Ishiwatari | Rizin World Grand Prix 2017 |
| 2019 | Lightweight | Tofiq Musayev | Patricky Freire | Rizin 20 |
| 2025 | Heavyweight | Alexander Soldatkin | Marek Samociuk | Rizin 51 |
Kickboxing Grand Prix winners
The Rizin Fighting Federation has occasionally hosted kickboxing tournaments under specialized rules, distinct from its more prominent MMA Grand Prix events, to showcase pure striking competitions among specialists. These tournaments emphasize stand-up exchanges without grappling, often featuring young Japanese talents against international challengers. The most notable such event was the 2017 Flyweight Kickboxing Grand Prix, held as part of the Rizin World Grand Prix Final Round on December 31, 2017, at the Saitama Super Arena.[131] In the 2017 tournament, undefeated prospect Tenshin Nasukawa, then just 19 years old, dominated the one-night, four-man bracket at 57 kg. Nasukawa advanced with a first-round TKO (three knockdowns) over Koji Takeda in the semifinals, followed by another first-round TKO via three knockdowns against Yamato Fujita in the final, securing the title in under five minutes of total fight time. This victory highlighted Nasukawa's explosive speed and knockout power, as all his tournament wins came via stoppage, aligning with Rizin's promotion of high-impact striking. The event drew international interest, with Nasukawa's performances elevating his profile ahead of future bouts against global kickboxers like Buakaw Banchamek.[147][148] Rizin's kickboxing rules adapt traditional stand-up formats for a more dynamic feel, using three three-minute rounds with MMA-style open-finger gloves to allow clinch work and elbows, while prohibiting ground fighting or submissions. Decisions follow a point-based system, but knockouts and referee stoppages are prioritized. This setup has led to notable upsets, such as underdog Yuta Hamamoto's 2017 semifinal advancement via decision over a favored opponent, showcasing the format's volatility for international entrants like Thai and Dutch strikers. Later years saw fewer full-scale kickboxing Grand Prix, with striking specialists integrated into hybrid cards rather than dedicated brackets. In 2023, kickboxing bouts at Rizin 42 included Buakaw Banchamek vs. Rukiya Anpo, which ended in a draw, focusing on individual matchups to highlight knockouts amid Rizin's MMA-heavy schedule. By November 2025, no major kickboxing Grand Prix had occurred that year, though events like Rizin Landmark 12 on November 3 incorporated striking-focused bouts under hybrid rules, maintaining the emphasis without a multi-fight elimination format.[149][140]Records and statistics
Title bout records
Kyoji Horiguchi holds the record for the most successful performances in Rizin title bouts, with five wins across the bantamweight and flyweight divisions, including defenses against Manel Kape and Darrion Caldwell, as well as capturing the flyweight crown from Kai Asakura in 2020.[150][100] The fastest knockout in a Rizin title fight took place on May 4, 2025, during the featherweight championship bout at Rizin: Otoko Matsuri, where undefeated challenger Razhabali Shaidullaev stopped defending champion Kleber Koike Erbst via strikes at 1:02 of the first round to claim the belt.[93][30] Rizin title bouts have featured rare draws, with no recorded instances in MMA championship fights as of November 2025, though non-title matches have seen occasional stalemates that influenced contender status. Undefeated challengers have occasionally tested incumbents, such as Seika Izawa maintaining her perfect 15-0 record while defending the women's super atomweight title multiple times, and Razhabali Shaidullaev entering his title-winning fight at 15-0.[93] In 2025 updates, Naoki Inoue achieved two consecutive bantamweight title defenses, outpointing Yuki Motoya via split decision on March 30 at Rizin 50 and Ryuya Fukuda via unanimous decision on July 27 at Super Rizin 4, solidifying his reign before an upcoming clash with Danny Sabatello.[151][110][152] Roberto de Souza (Satoshi) stands out for quickest title finishes, owning three of the top all-time fastest in Rizin history, including submission victories in lightweight defenses that averaged under two minutes.[153]Performance achievements
Mikuru Asakura holds the record for the most wins in Rizin history, with over 15 victories in the promotion as of 2025, showcasing his consistency and popularity in Japan's MMA scene.[154] His impressive tally includes notable decision wins and knockouts against top contenders, contributing to his status as one of Rizin's enduring stars. Jiri Prochazka established the longest win streak in Rizin with 8 consecutive victories from 2016 to 2019, during which he captured and defended the light heavyweight title through a series of dominant finishes.[155] This streak highlighted his aggressive style and finishing ability, with 7 of those wins ending before the final bell. Rizin events have set benchmarks for fan engagement and excitement, exemplified by the 2025 Otoko Matsuri at Tokyo Dome, which drew an attendance of 42,706 spectators.[156] Additionally, Rizin 40 in 2022 featured the most finishes on a single card, with 7 stoppages in 9 MMA bouts, underscoring the promotion's emphasis on conclusive outcomes over decisions.[157] In Grand Prix tournaments, fighters have achieved multi-division success without claiming weight-class titles, such as Mirko "Cro Cop" Filipovic's 2016 openweight victory, where he finished all four opponents en route to the trophy.[158] This feat demonstrated the physical demands and versatility required in Rizin's openweight format, influencing subsequent tournament structures.Champions by nationality
The Rizin Fighting Federation's championship landscape showcases a blend of domestic dominance and international representation, underscoring the promotion's evolution from a Japan-centric organization to one with broader global appeal. Japanese fighters have historically claimed the lion's share of titles, reflecting the promotion's cultural and developmental focus on local talent, while non-Japanese champions have grown in number since 2020, contributing to Rizin's diversification through partnerships and open-weight tournaments.| Nationality | Number of Titles | Notable Champions and Achievements |
