The term "dohyo" refers to the circular ring used in sumo wrestling competitions. It is made of clay and covered with a layer of sand, measuring approximately 4.55 meters in diameter. The dohyo is raised slightly above the ground, and its surface is carefully maintained to ensure safety and performance during matches. In Japanese culture, the dohyo holds significant importance, symbolizing the sacred space where wrestlers compete. Before each match, rituals are performed, including the throwing of salt to purify the ring. The dohyo is not just a physical space; it embodies the traditions and spirit of sumo.
