Kyokutenhō left the ring in tears after losing his twelfth bout of the July 2015 tournament, a result which meant his demotion to the second division was certain. He announced his retirement the following day, stating "I have run out of strength and don’t have the spirit anymore." Hakuhō gave him a ride in the "yokozuna"'s victory parade after winning the tournament. He became Ōshima-"oyakata," and began a coaching role at Tomozuna stable. His "danpatsu-shiki", or official retirement ceremony, was held in the Ryōgoku Kokugikan on 29 May 2016. It was announced in March 2017 that he would take over the running of Tomozuna stable after the May tournament, as the head coach (ex-"sekiwake" Kaiki) was about to reach the mandatory retirement age. Kyokutenhō said, "Since I belonged to two different stables, I hope to adopt good practices from both." The two coaches swapped elder names, with the former head of the stable staying as a consultant for a period of five years, under the Ōshima name, and Kyokutenho being known henceforth as Tomozuna Oyakata. The official handover took place on June 11, 2017 at a hotel in Tokyo with around 800 guests.
