A rikishi (力士) sumotori or, more colloquially, sumosan, is a professional sumo wrestler. Rikishi are expected to live according to centuries-old rules and, although there are some exceptions, most come from Japan, where sumo is practiced exclusively. Participation in official tournaments is the only means of marking achievement in sumo and the rank of an individual rikishi is based solely on official wins.
Makuuchi (幕内) or makunouchi (幕の内), is the top division of the six divisions of professional sumo. Its size is fixed at 42 wrestlers (rikishi), ordered into five ranks according to their ability as defined by their performance in previous tournaments.

Professional sumo is divided into six ranked divisions. Wrestlers are promoted and demoted within and between these divisions based on the merit of their win/loss records in official tournaments. For more information see kachi-koshi and make-koshi. Wrestlers are also ranked within each division. The higher a wrestler's rank within a division is, the stronger the general level of opponents he will have to face becomes. According to tradition, each rank is further subdivided into East and West, with East being slightly more prestigious, and ranked slightly higher than its West counterpart. The divisions, ranked in order of hierarchy from highest to lowest, are as follows:

Fujishima stable, formerly known as Musashigawa stable, is a stable of sumo wrestlers, part of the Dewanoumi ichimon or group of stables. It was set up in August 1981 by former yokozuna Mienoumi, who branched off from Dewanoumi stable. Since its founding Dewanoumi had a long tradition of not permitting its coaches to break away and form new stables, and Mienoumi was the first to amicably depart Dewanoumi stable since Tochigiyama set up Kasugano stable 62 years earlier. By the early 2000s it had become the strongest stable in sumo, with a yokozuna, three ōzeki and several other top division wrestlers. Wrestlers from the stable won six consecutive tournaments from March 1999 to January 2000. In September 2008 Mienoumi also became head of the Sumo Association.
Kasugano stable is a stable of sumo wrestlers, part of the Dewanoumi ichimon or group of stables. As of January 2019 it had 20 wrestlers. It has been led by former sekiwake Tochinowaka Kiyotaka since 2003.

The Mihogaseki stable 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 I. 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.
Musashimaru Kōyō is a former sumo wrestler. He made his professional debut in 1989, and reached the top makuuchi division in 1991.

He won over 700 top division bouts and took twelve top division tournament championships during his career. Musashimaru's sheer 235 kg (518 lb) bulk combined with 1.92 m of height made him a formidable opponent, and he was remarkably consistent and injury-free for most of his career. An amiable personality, his fan base was helped by a surprising facial resemblance to Japanese warrior hero Saigō Takamori. After retiring in 2003, he became an elder of the Japan Sumo Association and founded the Musashigawa stable in 2013.
Sōkokurai Eikichi is a professional sumo wrestler from Inner Mongolia, China. He is the only Chinese national to reach the top makuuchi division. Sōkokurai is of Mongolian descent.

However, in March 2013 his dismissal was nullified by the Tokyo District Court and after the Sumo Association decided not to appeal the decision he reappeared on the banzuke in July 2013 at the Nagoya Basho, ranked as a maegashira 15, the rank he was at when he was expelled. His highest rank to date of maegashira 2 was achieved in March 2017. He has won one special prize for Technique and one gold star for beating a yokozuna.
