Haguroyama Masaji (Japanese: 羽黒山 政司, November 18, 1914 – October 14, 1969) was a Japanese professional sumo wrestler from Nakanokuchi, Niigata. He was the sport's 36th yokozuna.[1] He was a yokozuna for a period of twelve years and three months dating from his promotion to that rank in May 1941 until his retirement in September 1953,[1] which was an all-time record until surpassed in 2019 by Hakuhō. During his career Haguroyama won seven top division championships and was runner-up on six other occasions. However, he was always in the shadow of yokozuna Futabayama, who came from the same stable.[2] After his retirement he was the head coach of Tatsunami stable until his death in 1969.
