Sakaigawa Namiemon

was a Japanese professional sumo wrestler from Katsushika District, Shimōsa Province. He was the sport's 14th yokozuna. Nicknamed "Tanikaze of the Meiji era", he's the only officially recognized yokozuna of the "yokozuna abuse era" following the fall of the Tokugawa shogunate. Masakichi joined the Sakaigawa stable where he was trained by the eponymous ōzeki (who held that rank from 1857 to 1861) and began his career in November 1857. Both shikona were inspired by the name of his previous employer's shop, and by the name of a famous sake brewery. Shihoyama brewery also purchased a new keshō-mawashi set.

Championships for the best record in a tournament were not recognized or awarded before the 1909 summer tournament and the above unofficial championships are historically conferred. For more information see yūshō.
