Hitachiyama Taniemon, Japanese sumo wrestler, the 19th Yokozuna (d. 1922)

Hitachiyama Taniemon (常陸山 谷右衞門, January 19, 1874 – June 19, 1922) was a Japanese professional sumo wrestler from Mito, Ibaraki Prefecture. He was the sport's 19th yokozuna from 1903 till 1914. His great rivalry with Umegatani Tōtarō II created the "Ume-Hitachi Era" and did much to popularise sumo. He is remembered as much for his exploits in promoting the sport as for his strength on the dohyō. In his later years as head coach of Dewanoumi stable he trained hundreds of wrestlers, including three yokozuna. Many consider him the most honorable yokozuna in sumo history, which earned him the nickname "Kakusei" (角聖), or "sumo saint".
