The streak was interrupted by a broken jaw that would force him to sit out the March 2009 tournament and fall from makushita #5 to makushita #45, but he stormed into jūryō on the back of five consecutive winning tournaments, including a runner-up finish to Akiseyama after winning the first two playoff rounds for the July 2009 championship.

Daidō was the third wrestler from Senshu University to achieve sekitori status, following already retired Musoyama and Katayama, the latter of whom was also from the same stable.

Daidō's performance was largely unaffected by the turmoil around the allegations and his successful tournaments earned him promotion to the top tier makuuchi division in July 2011.

Over the next two years he competed in thirteen basho at the top division, highlighted by a 10-5 finish in July 2012 to move up to maegashira #8 for two tournaments.

After a 1–14 finish in the July 2013 tournament he was demoted back to the jūryō division, where he mostly stayed for his final two and half years as a competitor.

Daidō dropped out of jūryō after the July 2015 tournament, and although he managed an immediate return, a 6-9 performance in November 2015 followed by a 1-4 start at makushita 2 in January 2016 motivated him to retire.

[1] In January 2018, he became the owner of the Otowayama kabu, replacing ex-Otowayama Oyakata Kōbō, who had it on loan and left the Japan Sumo Association.
