Sumo Wrestler
A rikishi, sumōtori or, more colloquially, osumōsan, is a professional sumo wrestler. Rikishi follow and live by the centuries-old rules of the sumo profession, with most coming from Japan, the only country where sumo is practiced professionally. Participation in official tournaments is the only means of marking achievement in sumo, with the rank of an individual rikishi based solely on official wins.
