After three straight losses in the January 2010 tournament, Chiyotaikai announced his retirement from sumo. His final match was against his longtime "ōzeki" rival Kaiō (who also broke the record for most "makuuchi" wins in this bout.) "I gave myself an ultimatum, so I don't have any regrets. I just don't have the power to continue wrestling my brand of sumo anymore," said Chiyotaikai. He remained as a coach at his stable under the "toshiyori" name of Sanoyama-"oyakata". He had his "danpatsu-shiki", or formal retirement ceremony, at the Ryōgoku Kokugikan on October 2, 2010. Shortly after the death of Chiyonofuji on July 31, 2016, Chiyotaikai was confirmed as the new head coach of Kokonoe stable, changing his name from Sanoyama to Kokonoe-"oyakata".
