Tosayutaka Yūya (born 10 March 1985) is a former sumo wrestler from Tosa City, Kōchi Prefecture, Japan.

After a long hiatus due to injury, he worked his way back up the ranks, logging several lower division championships on the way.

His comeback from sandanme 84 was the lowest any wrestler since World War II has fallen and still managed to again reach the top division,[1] until surpassed by Terunofuji.

Possibly due to stress from the then ongoing investigation into the hazing scandal at his stable, as well as an injury to his toe on the 12th day, Tosayutaka only managed an uncharacteristic 6-9 record.

His first demotion dropped him to the top makushita slot, but a convincing 4-3 record put him straight back in jūryō for the July 2008 tournament in Nagoya.

However, he had made a complete recovery upon his return and achieved a perfect record and the sandanme championship after a playoff win.

He returned to makuuchi in January 2015, a comeback from the rank of sandanme 84 in March 2013 - which at the time was the lowest any top division wrestler earning promotion back has fallen.

[2] His appointment continues the association of the head of the stable with the Tokyo University of Agriculture, which Tokitsuumi and Yutakayama Katsuo also attended.
