Hōchiyama Kōkan (born January 18, 1982, as Yukimi Munakata) is a former sumo wrestler from Hirosaki, Aomori Prefecture, Japan.

Hōchiyama was a member of Kizukuri High School sumo club (also attended by Mainoumi) and he made his professional debut in March 2000.

Hōchiyama took the jonokuchi championship with a perfect 7-0 record in his first tournament as a rikishi and he earned promotion to sandanme in November 2000 with another 7-0 score.

He narrowly missed out on promotion to the second highest jūryō division a number of times, recording 3-4 marks at makushita 1 in July 2004 and November 2005.

However, restricted by diabetes, a disastrous performance of 2-13 at the rank of jūryō 6 in the March 2008 tournament (which was his sixth consecutive losing score) saw him demoted to the third division for May.

He was one of seven rikishi from Sakaigawa stable ranked in jūryō in September 2010, the others being Iwakiyama, Gōeidō, Toyohibiki, Sadanoumi, Sadanofuji and Shironoryū.

He had 29 tournaments at a sekitori rank; normally 30 are required to become an oyakata but Hochiyama was allowed because his stablemaster and previous owner of the stock acted as guarantors, under new Sumo Association rules brought in on November 17, 2013.
