Dohyo-iri is a traditional ceremony in sumo wrestling that marks the entrance of wrestlers into the ring, known as the dohyo. This ritual is performed before matches and serves to purify the ring and honor the sport's traditions. Wrestlers, or rikishi, wear ceremonial attire and perform specific movements, including stomping and clapping, to ward off evil spirits. The ceremony is an important aspect of sumo culture, showcasing the wrestlers' respect for the sport and its history. Dohyo-iri is often accompanied by the presence of gyoji, or referees, who oversee the proceedings and ensure that the rituals are performed correctly.
