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.

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:
