A in the sport of Sumo is the highest rank any wrestler (Rikishi) can attain. The word means "Horizontal Rope" and it comes from one of the symbols that Yokozuna wear; a thick rope (綱 "tsuna") which is worn around the waist. It is a sign of their rank. This rope can be very heavy, weighing around . It is not worn for fights, but only for the wrestler's entrance ceremony into the ring at the start of a tournament. The rope is similar to that which is used in Shinto religion for purification and to mark off sacred areas of the temple.
