The Mihogaseki stable (三保ヶ関部屋, Mihogaseki-beya) was a stable of sumo wrestlers, part of the Dewanoumi ichimon or group of stables. Its last head coach, former ōzeki Masuiyama Daishirō II who took charge in November 1984, was the son of the previous head, also an ōzeki under the name Masuiyama Daishirō. He produced nine sekitori in that time, the last being the Russian Aran in July 2008. Until September 2006 the stable also had Baruto in the top division, but he later moved to a newly formed stable, Onoe. Being close to the mandatory retirement age, Mihogaseki wound his stable up in October 2013, with himself and his remaining wrestlers moving to Kasugano stable. Aran chose to retire instead.

Kise stable (木瀬部屋, Kise-beya) is a stable of sumo wrestlers, part of the Dewanoumi ichimon or group of stables. It was established in its current form in December 2003 by former maegashira and Nihon University amateur champion Higonoumi, who branched off from Mihogaseki stable. The stable's first top division wrestler was Kiyoseumi in January 2008. Its foreign recruit, Georgian Gagamaru, in May 2010 earned promotion to the top division. It is a popular destination for wrestlers with collegiate sumo experience like its stablemaster, and the retirement of Gagamaru in November 2020 opened up another spot for a foreigner.Following the demotion of Kise-oyakata (or stablemaster) in May 2010 after a scandal involving the selling of tournament tickets to members of the yakuza, Kise stable was dissolved with all 27 of its wrestlers moving to the affiliated Kitanoumi stable. Kise was allowed to reestablish the stable in April 2012. All former members, as well as newcomers Jōkōryu and Sasanoyama (now Daiseidō), joined the reconstituted stable. Jōkōryu reached the rank of komusubi in 2014, but has since fallen greatly down the ranks due to injury, and Daiseidō in September 2017 became the eleventh wrestler from Kise to reach jūryō since its founding in 2003. As of January 2022, it has 25 wrestlers, six of them are sekitori (salaried ranks). Kise stable's first makuuchi championship was delivered by Tokushōryū in the January 2020 tournament. The 33-year-old won from the bottom-most makuuchi rank of maegashira 17, after spending all but one of the previous 12 tournaments in the jūryō division.In May 2022 the stable recruited the first ever student of the University of Tokyo, an elite academic institution, to join professional sumo.

Oguruma stable (尾車部屋, Oguruma-beya) was a stable of sumo wrestlers, one of the Nishonoseki group of stables. In its modern form it existed from March 1987 when it was founded by Kotokaze, a former Sadogatake stable wrestler., until February 2022. The first wrestler from the stable to achieve sekitori status was Tomikaze in July 2000. Initially the stable had a policy of not accepting foreign born wrestlers or college recruits, but this was waived when Chuo University graduate Takekaze personally asked to join in 2002. Their first foreigner was the Mongolian Hoshikaze, who joined in the same year and eventually reached jūryō but was thrown out of sumo after the 2011 match-fixing scandal. The stable absorbed Oshiogawa stable in 2005 ahead of the retirement of Oshiogawa-oyakata, with Wakakirin and Wakatoba among the wrestlers transferring over. As of January 2022, it has 14 wrestlers. The stable produced seven makuuchi or top division wrestlers - Takekaze, Yoshikaze, Wakakirin, Kimikaze, Amakaze, Yago and Tomokaze.Kotokaze announced on 25 December 2021 that Oguruma stable would close following the January 2022 sumo tournament. The closure officially took place on 7 February 2022, with the stable's personnel being split between a new Oshiogawa stable run by the former Takekaze, and Nishonoseki stable, with the former Yoshikaze assisting the coaching there.

Takadagawa stable (高田川部屋, Takadagawa-beya) is a stable of sumo wrestlers, one of the Nishonoseki ichimon or group of stables. It was formed in 1974 by former ōzeki Maenoyama, and was originally in the Takasago group of stables, but was excommunicated from that group in 1998 due to disagreement over group nominations to the Japan Sumo Association's board of directors. Maenoyama handed over control to former sekiwake Akinoshima in 2009, as he was approaching the mandatory retirement age. A series of wrestlers from Taiwan were recruited in the late 1980s. Later a Mongolian, Maenoyu, was at the stable from 2004 until 2007, but there have been no foreigners recruited since Maenoyu's retirement and the current stablemaster has indicated there are no plans to do in the immediate future.The stable did not have any sekitori between Dairaidō′s last appearance in jūryō in July 2006 and the promotion of Ryūden in September 2012, where he lasted for only one tournament. In September 2014 Kagayaki reached jūryō, ending Takadagawa's sekitori drought. Kagayaki went on to reach the top makuuchi division in January 2016, the first Takadagawa wrestler to do so since Kenkō in 1992, and Ryūden returned to jūryō in November 2016, reaching the top division himself in January 2018. The new Takadagawa head ended the stable's nearly thirteen years of non-alignment with an ichimon in January 2011 when he was accepted into the Nishonoseki group. As of January 2022, it had 22 wrestlers. On 10 April 2020, the Sumo Association announced that an undisclosed wrestler had tested positive for the coronavirus. It was later confirmed to be Shobushi of Takadagawa Stable, a sandanme wrestler who died from coronavirus complications on 13 May 2020. It had also been announced in late April 2020 that seven individuals, including Takadagawa's stablemaster and jūryō wrestler Hakuyozan, were hospitalized after testing positive for the virus. The stable was only one of the 45 stables in sumo not included in the "all-clear" antibody test results issued by the Sumo Association on 6 July 2020. The tate-gyōji at the stable, Shikimori Inosuke, missed the July 2020 tournament with an unspecified illness.

Shikoroyama stable (錣山部屋, Shikoroyama beya) is a stable of sumo wrestlers, formerly part of the Tokitsukaze ichimon or group of stables. It was established in its current form in February 2004 by former sekiwake Terao, who branched off from Izutsu stable. He did not take any established wrestlers with him, recruiting all the wrestlers himself instead. In December 2017 Shikoroyama Oyakata left the Tokitsukaze group along with Tatsutagawa Oyakata (ex-Homasho) and Minato Oyakata (ex-Minatofuji), announcing that he would not join any other ichimon but would support Takanohana in the January 2018 elections to the board of the Japan Sumo Association. In September 2018 the stable joined the Nishonoseki group. As of January 2022, the stable had 18 wrestlers. Hamatensei (real name Issei Amakusa), a junior wrestler who competed for the stable from 2011 to 2019, became a civil servant after completing a correspondence course as part of an arrangement between the Japan Sumo Association and NHK Gakuen senior high school.

Ōtake stable (大嶽部屋, Ōtake-beya) is a stable of sumo wrestlers, one of the Nishonoseki group of stables.

Yamahibiki stable (山響部屋, Yamahibiki-beya) is a stable of sumo wrestlers, part of the Dewanoumi ichimon or group of stables. It was set up in 1985 as Kitanoumi stable by former yokozuna Kitanoumi, who branched off from Mihogaseki stable. It absorbed Hatachiyama stable in 2006, following the death of its head coach, former ōzeki Hokuten'yū. In May 2010 it also absorbed Kise stable, which was forced to close after its stablemaster, former maegashira Higonoumi, was implicated in the selling of tournament tickets to yakuza members. As a result of this move the stable had 46 wrestlers, making it by some margin the largest stable in sumo at this time. It was the first stable to have over 40 wrestlers since Futagoyama stable in 1998, and had difficulty in finding room for so many. As a result, Kise was allowed to reestablish the stable in April 2012, and all former members of Kise stable, as well as newcomers Jōkōryū and Sasanoyama who had been recruited by Kise-oyakata, joined the reconstituted stable again. Stablemaster Kitanoumi died of colorectal cancer and multiple organ failure on the evening of November 20, 2015. Former maegashira Ganyū, who had been serving as a coach at the stable, inherited it. The stable was renamed Yamahibiki, the elder name used by Ganyū, since the Kitanoumi name could not be inherited, due to it being a one-generation elder stock or ichidai-toshiyori. As of January 2022, Yamahibiki stable had 15 wrestlers. Following the demotion of Kitataiki after July 2017 tournament and Kitaharima after September 2017 tournament, it had no sekitori for the first time since May 2003.

The revenge of the forty-seven rōnin (四十七士, Shijūshichishi), also known as the Akō incident (赤穂事件, Akō jiken) or Akō vendetta, is a historical 18th-century event in Japan in which a band of rōnin (lordless samurai) avenged the death of their master. The incident has since become legendary. It is one of the three major adauchi vendetta incidents in Japan, alongside the Revenge of the Soga Brothers and the Igagoe vendetta.The story tells of a group of samurai who were left leaderless after their daimyō (feudal lord) Asano Naganori was compelled to perform seppuku (ritual suicide) for assaulting a powerful court official named Kira Yoshinaka. After waiting and planning for a year, the rōnin avenged their master's honor by killing Kira. They were then obliged to commit seppuku for the crime of murder. This true story was popularized in Japanese culture as emblematic of the loyalty, sacrifice, persistence, and honor that people should display in their daily lives. The popularity of the tale grew during the Meiji era, during which Japan underwent rapid modernization, and the legend became entrenched within discourses of national heritage and identity. Fictionalized accounts of the tale of the forty-seven rōnin are known as Chūshingura. The story was popularized in numerous plays, including in the genres of bunraku and kabuki. Because of the censorship laws of the shogunate in the Genroku era, which forbade portrayal of current events, the names were changed. While the version given by the playwrights may have come to be accepted as historical fact by some, the first Chūshingura was written some 50 years after the event, and numerous historical records about the actual events that predate the Chūshingura survive. The bakufu's censorship laws had relaxed somewhat 75 years after the events in question in the late 18th century when Japanologist Isaac Titsingh first recorded the story of the forty-seven rōnin as one of the significant events of the Genroku era. To this day, the story remains popular in Japan, and each year on 14 December, Sengakuji Temple, where Asano Naganori and the rōnin are buried, holds a festival commemorating the event.

The Tokitsukaze stable (時津風部屋, Tokitsukaze-beya) is a stable of sumo wrestlers in Japan, one of the Tokitsukaze group of stables. It was founded in 1769 and was dominant during the Taishō period. In its modern form it dates from 1941 when it was established by Futabayama, who was still an active wrestler at the time. It was known as Futabayama Dojo until it was re-named Tokitsukaze stable in November 1945 when Futabayama retired. (The stable has the names of both Futabayama and Tokitsukaze at its entrance.) Upon Futabayama's death in 1968 the former Kagamisato took charge for a short time, but Futabayama's widow wanted Yutakayama Katsuo to take over, which he did upon his retirement in 1969. He in turn passed control of the stable on to his successor Futatsuryū in August 2002. As of January 2022 it had 17 active wrestlers, two of whom are sekitori. The death of 17-year-old junior member Tokitaizan (real name Takashi Saito) in a hazing scandal on June 26, 2007, eventually resulted in the dismissal and six years in prison for Futatsuryū. This compelled Tokitsuumi, a long time top division wrestler from the stable, to retire from active sumo and take over as the new head of the stable.Tokitsuumi was asked by the Japan Sumo Association to retire in February 2021 after twice violating COVID-19 safety protocols. Tokitsukaze stable was taken over by former maegashira Tosayutaka.
