About Yoshibayama Junnosuke
Yoshibayama Junnosuke, real name Ikeda Junnosuke, was a Japanese professional sumo wrestler from Atsuta District, Hokkaido. He was the sport's 43rd yokozuna. He suffered a number of injuries and only won one tournament championship, but was a popular wrestler. He was a runner-up five times, and earned three special prizes and two gold stars in his top division career. After his retirement in 1958 he revived and led the Miyagino stable until his death in 1977. Yoshibayama was promoted to yokozuna after winning his first championship with a perfect 15–0 record in January 1954, but did not win a single bout at the rank until the autumn tournament of that year. Yoshibayama could have been awarded a win, but sportingly insisted on a draw. His old rival Kagamisato, who had been promoted to ōzeki alongside him in May 1951, also decided to retire on the final day, the first time that two yokozuna had quit in the same tournament.
