Tochinoumi stayed in the sumo world as an elder of the Sumo Association, under the name Nakadachi. Somewhat unusually for a former "yokozuna", he did not immediately take charge of a stable, instead working as an assistant coach. However, in January 1990 he did become head coach of Kasugano stable after the death of the previous stablemaster, the former Tochinishiki. Among the "sekitori" he produced were Tochinonada, Tochinohana, Tochisakae, and Kasuganishiki. He later expressed satisfaction that he had managed to maintain the tradition of an unbroken string of "sekitori" at Kasugano stable dating back to before the second World War. He stood down in 2003 upon reaching the mandatory retirement age of 65, handing control of the stable over to former "sekiwake" Tochinowaka. He was one month younger than Sadanoyama, who was promoted to "yokozuna" a year after him. Following the death of Sadanoyama in April 2017, he was the oldest living "yokozuna", but he remained active by playing golf. In 2018 he visited Kasugano stable and participated in the ceremony to mark Tochinoshin's promotion to "ōzeki". In 2019 he organized the Tochinoumi Cup, a sumo tournament for children, in his home village of Inakadate, Aomori. He died in January 2021 of aspiration pneumonia at the age of 82. He was the second longest living "yokozuna" of all-time, after Umegatani I.
