Yokozuna

Yokozuna (横綱) is the highest rank in sumo. The name literally means "horizontal rope" and comes from the most visible symbol of their rank, the rope (綱) worn around the waist. The rope is similar to the shimenawa used to mark off sacred areas in Shinto, and like the shimenawa it serves to purify and mark off its content. The rope, which may weigh up to 20 kg, is not used during the matches themselves, but is worn during the yokozuna's dohyo-iri ring entrance ceremony.

History of yokozuna
The birth of the rank of yokozuna is unclear, and there are two competing legends. According to one, a 9th-century wrestler named Hajikami tied a shimenawa around his waist as a handicap and dared any to touch it, creating sumo as it is now known in the process. According to the other, legendary wrestler Akashi Shiganosuke tied the shimenawa around his waist in 1630 as a sign of respect when visiting the Emperor, and was posthumously awarded the title for the first time. There is little supporting evidence for either theory—in fact, it is not even certain that Akashi actually existed—but it is known that by November 1789, yokozuna starting from the fourth yokozuna Tanikaze Kajinosuke and the fifth yokozuna Onogawa Kisaburō were depicted in ukiyo-e prints as wearing the shimenawa. These two wrestlers were both awarded yokozuna licences by the prominent Yoshida family.

Before the Meiji Era, the title yokozuna was conferred on ōzeki who performed sumo in front of the Shogun. This privilege was more often determined by a wrestler's patron having sufficient influence rather than purely on the ability and dignity of the wrestler. Thus there are a number of early wrestlers who were, by modern standards, yokozuna in name only. In these early days yokozuna was also not regarded as a separate rank in the listings, but as an ozeki with special dispensation to perform his own ring entering ceremony.

At first, the Yoshida family and a rival family, Gojo, fought for the right to award a wrestler a yokozuna licence. The Yoshida family won this dispute, because the 15th yokozuna Umegatani Tōtarō I, one of the strongest wrestlers, expressed his wish that he be awarded a licence by the Yoshida family in February 1884, and Gojo licences are no longer recognized officially.

In May 1890, the name yokozuna was written on the banzuke for the first time due to the 16th yokozuna Nishinoumi Kajirō I's insistence that his yokozuna status be recorded. In February 1909, during the reigns of the 19th yokozuna, Hitachiyama Taniemon, and the 20th, Umegatani Tōtarō II, it was officially recognized as the highest rank. Since the establishment of the Yokozuna Deliberation Council (横綱審議委員会) on 21 April 1950, wrestlers have been promoted to yokozuna by the Japan Sumo Association. The first yokozuna promoted by the Sumo Association was the 41st yokozuna Chiyonoyama Masanobu.

Criteria for promotion to yokozuna
In modern sumo, the qualifications that an ōzeki must satisfy to be promoted are that he has enough power, skill and dignity/grace (品格 hinkaku) to qualify. There are no absolute criteria, nor is there a set quota: there have been periods with no wrestlers at yokozuna rank, and there have been periods with as many as four simultaneously.

The power and skill aspects are usually considered with reference to recent tournament performance. The de facto standard is to win two consecutive championships as ōzeki or an equivalent performance. In the case where the "equivalent performance" criterion is used the wrestler's record over the previous three tournaments is taken into account with an expectation of at least one tournament victory and two runner-up performances, with none of the three records falling below twelve wins. Thus a consistent high level of performance is required. Winning two tournaments with a poor performance between them is not usually sufficient. The rules are not set in stone and hence in reaching their conclusion the Yokozuna Deliberation Council and Sumo Association can interpret the criteria more leniently or strictly and also take into account other factors, such as total number of tournament victories, the quality of the wins and whether the losses show any serious vulnerabilities.

The issue of hinkaku (dignity and grace) is more contentious, as it is essentially a subjective issue. For example Hawaiian-born ōzeki Konishiki, in particular, was felt by many to be unfairly kept from yokozuna status due to his non-Japanese origin, and many Sumo Association members even openly said that foreigners (gaijin) could never achieve the hinkaku needed to be a yokozuna. In the case of Konishiki, other issues such as his weight were also cited. Other wrestlers have also been held back. For example Chiyonoyama in the 1950s was not immediately promoted due to his relative youth despite winning consecutive tournaments, although he later achieved the top rank. On the other hand, Futahaguro was given the title of yokozuna in 1986, despite immaturity being cited in opposition to his promotion. After being promoted, he was involved in several misbehaviors that embarrassed the Sumo Association such as hitting one of his tsukebitos (manservant or personal assistant) over a trivial matter in a scandal that had six of his seven tsukebitos decide to leave him. The promotion again proved to be a fiasco when it was later revealed that he had a heated argument with his stable boss, Tatsunami, and stormed out of the heya, allegedly striking Tatsunami's wife on the way. Futahaguro eventually retired after only one and a half years at the top rank and became the only yokozuna in sumo history ever to retire without having won at least one top division championship.

The debate concerning foreigners having the dignity to be a yokozuna was finally laid to rest on 27 January 1993, when ōzeki Akebono was formally promoted to yokozuna after only eight months as an ōzeki. Since then, the issue of whether foreigners have the necessary dignity has become a moot point as the last four wrestlers to achieve sumo's ultimate rank over a thirteen-year period have all been foreigners: Musashimaru, Asashōryū, Hakuhō, and Harumafuji.

Becoming a yokozuna
Elevation to yokozuna rank is a multi-stage process. After a tournament, the Yokozuna Deliberation Council, a body of lay people (that is, not former sumo wrestlers) who are appointed by the Japan Sumo Association to provide an independent quality control on Yokozuna promotion, meet and discuss the performance of the top-ranked wrestlers. Usually at the instigation of the Japan Sumo Association they can make a recommendation that a particular ōzeki-ranked wrestler has the necessary attributes to be promoted. Their recommendation is then passed to the Judging division and then the Board of Directors of the Sumo Association who make the final decision.

If a wrestler is deemed to have met the criteria then he will be visited in his training stable by a member of the Sumo Association Board of Directors who will formally give him the news. In the following days a yokozuna hawser will then be made in his stable and he will practice the ring entrance ceremony with advice from a previous or current yokozuna. Finally he will have his inaugural ceremonial ring entry ceremony held at Meiji Shrine in Tokyo, which is usually completed within a couple of weeks of the tournament end.

In competition in each tournament for the championship he can never be relegated. A yokozuna is expected to retire if he can no longer compete at the peak of the sport.

Yokozuna ceremonies and traditions
The formal birth of the rank from Tanikaze's time appears to have in part come from a desire to let the very best have a separate ring entry ceremony (dohyō-iri) from the remaining top division wrestlers. The dohyō-iri is a ceremonial presentation of all the top division wrestlers which is held before the competitive bouts of the day. The normal ceremony for top division wrestlers is to be introduced and form a circle around the wrestling ring (dohyō) wearing specially decorated heavy silk "aprons", called keshō-mawashi. A brief symbolic "dance" is carried out before filing off to change into their fighting mawashi and prepare for their bouts.

A yokozuna, however, is introduced after the lower ranked wrestlers and is flanked by two other top division wrestler "assistants". The "dewsweeper" or tsuyuharai precedes the Yokozuna, while the "sword bearer" or tachimochi follows him into the arena. The sword is a Japanese katana and symbolises the samurai status of the yokozuna. The tachimochi will always be the more highly ranked of the assisting wrestlers. As indicated above, during the ceremony the yokozuna will wear his tsuna around his waist. The ceremonial aprons of all three form a matching set.

Once in the ring the yokozuna takes centre stage and performs a much more complex ritual dance. The dance can take one of two forms, one of which the yokozuna usually chooses when he is first promoted. In addition to the slightly different routine the choice of the yokozuna's ritual can also be determined by the knot used to tie the rope around his waist. The currently more popular "Unryū" style has only one loop at the back, while the "Shiranui" style has two. The styles are named after 10th yokozuna Unryū Kyūkichi and 11th yokozuna Shiranui Kōemon of the Edo period, although there is no historical proof that they actually carried out the dances that have been attributed to them. Indeed there are some scholars who believe that in fact the two concerned have had their ring entering rituals mixed up.

If a former yokozuna reaches the age of 60, he usually performs a special ring-entering ceremony known as kanreki dohyō-iri, in celebration of his longevity.

If a yokozuna is defeated by a maegashira ranked wrestler, it is common and expected for audience members to throw their seat cushions into the ring (and onto the wrestlers).

As of September 2012, there have been a total of 70 yokozuna, although formal record keeping only started with Tanikaze and Onogawa in 1789.
