The term "Dohyo" refers to the circular ring used in the sport of sumo wrestling. It is made of clay and covered with a layer of sand, creating a surface where wrestlers compete. The Dohyo is typically 4.55 meters in diameter and is raised slightly above the ground, providing a distinct area for matches.
In addition to its physical structure, the Dohyo holds cultural significance in Japanese traditions. Before each match, rituals are performed, including the throwing of salt to purify the ring. The Dohyo serves as a sacred space where wrestlers, known as rikishi, showcase their skills and strength.
