A rikishi (力士), sumōtori (相撲取り) or, more colloquially, osumōsan (お相撲さん), 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.
A sekitori (関取) is a rikishi (力士, sumo wrestler) who is ranked in one of the top two professional divisions: makuuchi and jūryō. The name literally translates to having taken the barrier, as only a relatively small fraction of those who enter professional sumo achieve sekitori status.
