Controversies in professional sumo

Kiyoseumi was forced to retire after an investigation found him guilty of match-fixing.

Due to the hierarchical structure of the sport, where top ranked wrestlers have great advantages in salary and status over lower ranked wrestlers, speculation about the existence of match-fixing and isolated reports of match fixing have surfaced over the years.[1][2] The Japan Sumo Association (JSA) repeatedly denied any wrestlers were involved in match-fixing, known as yaocho, and even took publishers to court over such allegations.[3][4]

However, in 2011, it was announced that an investigation by police had discovered cell phone text messages indicating that a number of matches had been fixed.[5] Allegedly, 14 wrestlers and a few stablemasters were involved. In the course of the investigation, several wrestlers eventually admitted to match-fixing for money.[3][6] As a consequence, the board of directors of the JSA decided in an extraordinary meeting to cancel the March 2011 tournament in Osaka, the first time this had happened since 1946.[7] In all, fourteen wrestlers were judged guilty of match-fixing, to which most of them admitted involvement. All of the wrestlers judged to be involved were forced to retire.

The JSA's investigative panel stated in May 2011 that match-fixing appears to have been widespread. The panel stated that it would be difficult to discover, however, the full extent of the problem.[8] The May 2011 tournament went ahead but with no sponsorship, live TV coverage or trophy presentations, and was referred to as the "Technical Examination Tournament" with free admission to spectators.[9]

One wrestler charged with match-fixing, Sōkokurai, strenuously denied any involvement and won a court case in early 2013 deeming his dismissal groundless. He was subsequently reinstated by the JSA, and appeared in the July 2013 tournament in the top division.[10]

On July 4, 2010, the Japan Sumo Association announced its decision to dismiss the ōzeki Kotomitsuki and the stablemaster Ōtake, former Takatōriki, for betting on baseball games in a gambling ring run by the yakuza.[11][12] At the same time, two stable masters were demoted and an unprecedented 18 wrestlers banned from the July 2010 tournament.[13] The betting scandal resulted in public broadcaster NHK opting not to air live sumo matches during the tournament, instead showing a daily highlight package. A number of sponsors also withdrew their support for the tournament.[14] Sumo Association chairman Hanaregoma declared in August 2010 that "violent groups or antisocial forces" were being banned from accessing tournament venues, training stables and other facilities.[15]

Three months before Hanaregoma's announcement, Japan's largest yakuza group, Yamaguchi-gumi, bought fifty prized seats during a tournament so that gangsters were prominently visible during the national broadcast of the match. According to experts, this was an endeavor to cheer up an incarcerated boss.[13] Although there have always been alleged ties between sumo and the yakuza, the sport has suffered from waning public interest and sponsorship during the economic recession, which may have contributed to closer ties to the underworld for financial support.[16]

In December 2021 sekitori wrestlers Hidenoumi and Shiden were withdrawn from the January 2022 tournament for suspected involvement in illegal gambling. During the investigation into an illegal establishment in Sōka, Saitama Prefecture that was raided in September 2021, suspicions were raised by the Saitama Prefectural Police about the involvement of both Hidenoumi and Shiden, as well as other sumo wrestlers that may have possibly participated.[17] During the January 2022 basho Japanese media reported that the Sumo Association's compliance committee, after holding hearings, concluded that Hidenoumi and Shiden participated in illegal gambling.[18][19] Following the tournament's conclusion, the Sumo Association suspended Hidenoumi for one tournament (retroactive to January 2022) and issued a 20% salary cut for two months. No disciplinary action was taken against Shiden. Their stablemaster Kise (former maegashira Higonoumi) was issued a warning.[20] Police declined prosecution the following month.[21]

In October 2023 it was revealed that several employees of the Japan Sumo Association had lodged complaints with the Board of Directors about the supervision of certain non-elder managers. After an investigation, it was revealed that the administrative affairs chief and the head of the office in charge of accounting were responsible for numerous irregularities dating back to 2017 concerning the payment of overtime pay for an estimated amount of 100 million yen (~$667,870/€637,712). Having initially sought to resolve the problem internally in August, the Association received twelve formal complaints from staff who were dissatisfied with the way the matter was being handled. At the same time, it was also reported that the same two managers had unilaterally reduced the salaries of certain employees, restricted access to the computer server and asked intrusive questions to women during recruitment interviews about their pregnancy and childbirth plans. Finally, it was also confirmed that both men had verbally abused employees. In response to these actions, the Sumo Association decided to suspend its administrative affairs chief for one month, and demote the head of the office in charge of accounting by one rank in the Association hierarchy.[32]

The sumo lifestyle has negative health effects which become apparent later in life. Sumo wrestlers have a life expectancy between 60 and 65, more than 20 years shorter than the average Japanese male, as the diet and sport take a toll on the wrestler's body. Many develop type 2 diabetes or high blood pressure, and they are prone to heart attacks due to the enormous amount of body mass and fat that they accumulate. The excessive intake of alcohol can lead to liver problems and the stress on their joints due to their excess weight can cause arthritis. Recently, the standards of weight gain are becoming less strict, in an effort to improve the overall health of the wrestlers.[33][34]

Professional sumo excludes women from competition and ceremonies. Women are not allowed to enter or touch the sumo wrestling ring (dohyō), a tradition stemming from Shinto and Buddhist beliefs that women are "impure" because of menstrual blood.[35]

The female Governor of Osaka from 2000–2008, Fusae Ohta, when called upon to present the Governor's Prize to the champion of the annual Osaka tournament, was required to do so on the walkway beside the ring or send a male representative in her place. She repeatedly challenged the JSA's policy by requesting to be allowed to fulfill her traditional role as Governor. Her requests were repeatedly rejected until the end of her five-year term.

In April 2018, during a non-tournament sumo event in Kyoto Prefecture, two women rushed to the aid of the mayor of Maizuru when he collapsed in the middle of the dohyō. While the women were attempting to provide emergency treatment, a referee repeatedly asked them to leave the ring. The chairman of the Sumo Association later apologized for what he called an inappropriate response, saying that he greatly appreciated the women's efforts.[36]

The view of those who criticize this continuing "men-only" policy is that it is discriminatory and oppressive.[37] In general, women in the sumo world are only expected to be supportive wives of the wrestlers, and, in the case that their husband has become a stablemaster, a surrogate mother for all of his trainee wrestlers.[22] The view of the JSA is that this is a tradition that has been firmly maintained through the centuries, so it would be a dishonor to all of their ancestors to change it.[37]

This was not always the case. Starting as early as the 18th century a form of female sumo (女相撲, onnazumo) was performed in some areas of Japan.[38] In the cities it was more of a spectacle often associated with brothels. However, in some areas of Japan female sumo had a serious role in certain Shinto rituals. In later years, there were limited tours of female sumo that lasted for a time.[39] However, female sumo is not considered to be authentic by most Japanese and is now prohibited from taking place beyond amateur settings.[40]
