On May 30, 2018, the Japan Sumo Association held its ranking committee and then an extraordinary meeting of its board. The board approved the promotion of Tochinoshin to ōzeki by unanimous decision.
Then messengers from the association went to his stable. Izutsumi Oyakata told him: Zenkai itchi de ōzeki ni suikyo saremashita. “You have been recommended for ōzeki by unanimous decision.” Tochinoshin answered with a formal speech of acceptance, the kōjō: “I humbly accept. I will keep my stable master’s teaching and devote myself to training, so that I become a model for wrestlers.”
