He returned to the rank of komusubi on two other occasions, November 1983 and March 1984, but finished with losing records in both tournaments.
In Mach 1985, Sadanoumi was ranked at maegashira 13 and was on the verge of demotion if he did not perform well. He got off to a strong start and by the end of the 11th day, his record was 10-1 and he was tied in the lead alongside ozeki Wakashimazu. He eventually lost his last four matches as he was paired up against upper ranked wrestlers. Nevertheless, he finished with a strong 10-5 record and was awarded his second Fighting Spirit Prize.

He was demoted back down to juryo where he continued to struggle and he ultimately announced his retirement midway through the July 1988 tournament.
Retirement from Sumo[]
After retiring, Sadanoumi remained in the Sumo Association as an elder, but he was unable to obtain elder stock and instead borrowed from the names Hatachiyama, Nakadachi, and Tagonoura. He worked as a coach for Dewanoumi stable, but left the sumo world all together in August 1999. After leaving the sumo world, he opened up a chanko restaurant in Higashiosaka, Osaka, called "Sumo Teahouse Sadanoumi" (相撲茶屋 佐田の海).
Personal Life[]
His eldest son, Kaname (born 1987), was also a sumo wrestler and he joined Sakaigawa stable in March 2003. He was given his father's shikona, Sadanoumi, and he was promoted to the top makuuchi division in May 2014. Like his father, Sadanoumi had an impressive debut and they became the first father-son to win special prizes in their first makuuchi tournament.
He is close friends with now retired-top tokoyama Tokoyasu, both were from the same stable and were close in age. Even after becoming sekitori, Sadanoumi only allowed Tokoyasu to do his hair and the two strongly trusted each other. Before the both of them married, they interacted almost daily. When his son was promoted to the top division, he also had his hair done by Tokoyasu, despite them being in different stables and Tokoyasu already being the chief tokoyama and only technically supposed to do a yokozuna's hair.
Fighting Style[]
