The earliest "sumo map" we can see today is a mural of the Han Dynasty. Today, there is a sumo figure in the mural of Han Tomb in Dahuting, Mi County, Henan Province. Two sumo wrestlers naked, only around the triangle, chubby, similar to today's Japanese sumo wrestlers. According to research, this tomb was built in the Eastern Han Dynasty. During 1979, I visited the grottoes in Yan 'an. Near a reservoir in Fuxian County, I found a stone carving "Sumo Map" of the Western Wei Dynasty. Sumo wrestlers has been fighting, naked and wearing a triangular scarf. Sumo was also found in the murals of the Song Tomb in Jincheng, Shanxi, depicting four sumo wrestlers, two of whom were fighting and the other two stood on both sides to watch. They are all fat and naked, and shame is surrounded by a triangular scarf. It seems that the costumes of ancient and modern sumo wrestlers are similar.
