Rizin Fighting Federation#Women's Super Atomweight Championship

In 1997, Pride Fighting Championships was founded in Japan, promoted by Dream Stage Entertainment. The organization quickly rose up to become the world's most popular MMA promotion and helped to popularize the sport in Japan and in the world. Pride differentiated itself from the UFC with its focus on spectacle and entertainment, as well a more permissive ruleset.{{Cite web|last=Snowden|first=Jonathan|title=Sex, Drugs, Gangsters and MMA: Remembering Pride, UFC's Wild Predecessor|url=https://bleacherreport.com/articles/2718986-sex-drugs-gangsters-and-mma-remembering-pride-ufcs-wild-predecessor|access-date=2022-02-21|website=Bleacher Report|language=en}} By 2007, a scandal alleging its ties to the yakuza caused a financial decline that lead to the promotion folding. Dream Stage Entertainment was bought by Zuffa—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.

After Pride folded, most of DSE's former staff, fighters and executives joined Fighting and Entertainment Group, the promoters of K-1, to organize a successor, which became known as Dream.{{cite web |url=http://mmaweekly.com/absolutenm/templates/dailynews.asp?articleid=5691&zoneid=1 |title=K-1's new Dream includes Cro Cop |publisher=Mma Weekly |date=February 13, 2008 |access-date=February 25, 2009 |url-status=dead |archive-url=https://web.archive.org/web/20090203015848/http://mmaweekly.com/absolutenm/templates/dailynews.asp?articleid=5691&zoneid=1 |archive-date=February 3, 2009 }} However, FEG would have its own financial issues and went bankrupt in 2012. As a result, Dream became defunct.[http://www.muaythaitv.com/pages/news/news.php?s_id=2289 FEG's bankruptcy], May 17, 2012, Muay Thai TV

Three years after Dream folded, rumors began circulating that Pride and Dream founder Nobuyuki Sakakibara would return to the industry after an interview with Bellator MMA President Scott Coker was released.{{Cite web|title = Scott Coker: Former PRIDE boss Nobuyuki Sakakibara planning MMA return in 2015|url = https://mmajunkie.usatoday.com/2015/04/scott-coker-former-pride-boss-nobuyuki-sakakibara-planning-mma-return-in-2015|website=mmafighting.com| date=2 April 2015 |access-date = 2020-10-07}} On September 19, 2015, during Bellator MMA & Glory: Dynamite 1, it was announced that Sakakibara had signed former Pride Heavyweight Champion Fedor Emelianenko to headline a New Year's Eve Show in Tokyo for his new MMA promotion.[https://www.lowkickmma.com/fedor-emelianenko-returns-to-mma-on-new-years-eve/ Fedor Emelianenko Returns To MMA On New Year's Eve] Sakakibara held a press conference on October 8, 2015, with Nobuhiko Takada and other former Pride FC employees to formally announce the launch of "Rizin Fighting Federation".[https://mmamicks.com/rizin-what-its-about-and-what-we-can-expect/ RIZIN Japan - What We Can Expect From The Newcomer] Initial signees included Kazushi Sakuraba, Shinya Aoki, as well as female competitors Gabi Garcia and Rena Kubota.{{Cite web|title = Long after his prime, Kazushi Sakuraba is in the position to save Japanese MMA|url = https://www.mmafighting.com/2015/10/18/9494533/long-after-his-prime-sakuraba-is-in-the-position-to-save-japanese-mma|website=mmafighting.com| date=18 October 2015 |access-date = 2018-07-22}}

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 by knockout, submission, technical knockout by referee stoppage, or by judges' decision.

All strikes, throws and chokes are permitted, with the exception of headbutts and strikes to the back of the head, medulla oblongata, spinal cord or genitals.{{Cite web|title=RULES ルール|url=https://jp.rizinff.com/rule|website=Rizin Official Website|language=Japanese|access-date=2022-02-21}} Soccer kicks, knees and stomps to grounded opponents are also permitted. However, if there is a weight discrepancy of {{convert|15|kg|lb|abbr=on}} or more, the lighter fighter is allowed to choose if such ground attacks are permitted. Unlike Pride, Rizin allows the use of elbow strikes, including the 12–6 elbow.{{cite web|url=https://the-fighter.net/f/musings-on-new-rizin-rules-the-art-of-judging-and-jmoc|title=Musings on new RIZIN rules, the art of judging and JMOC|website=The Fighter|date=2021-06-01|access-date=2021-08-11}}

Fights are judged on the following criteria:

• 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.

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. Three knockdowns in a single round will result in a technical knockout. All forms of elbow strikes are illegal.
