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.
