Honbasho

Official sumo tournament

A honbasho , or Grand Sumo Tournament in English, is an official professional sumo tournament. Only honbasho results matter in determining promotion and relegation for rikishi on the banzuke ranking. The number of honbasho held every year and their length has varied; since 1958 there are six tournaments held over 15 consecutive days in four locations every year. Since 1926 the honbasho are organized by the Japan Sumo Association, after the merger of the Tokyo and Osaka sumo associations.
