Shiranui Kōemon, Japanese sumo wrestler, the 11th Yokozuna (born 1825)

Shiranui Kōemon was a Japanese professional sumo wrestler from Kikuchi, Higo Province. He was the sport's 11th yokozuna. He gives his name to one of the two styles for the yokozuna's in-ring ceremony, although the question of whether he himself practiced this style is highly debated.

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.
