Held here in Ryogoku since the Edo period, Sumo is a Shinto ritual, making the sumoring a sacred place. The base of the ring is made of pounded clay, with the ring made of clay-stuffed straw bales, known as 'Dohyo'. The sumo ring was originally named a 'Dohyoba' (place made of clay bales), since abbreviated to 'Dohyo'.
