	Hiroki was always a large boy and by the time he had graduated from Hyogo junior high school he was already 190 cm tall and weighted 120 kg. Hiroki was also a notable judoka at the prefectural level. This along with his exceeding size garnered him an invitation to join Nakamura stable. He made his debut in March 2005 and made steady progress up the banzuke. This continued until he reached Sandanme in March 2007 recording a mere three losing records on his way there. After a few losing records and bouncing between sandanme and Jonidan he returned to steady progress and was promoted to Makushita. This is where he would spend most of his career. He was helped along by the 2011 match fixing scandal which saw many wrestlers forced to retire, and in September 2011 was promoted to his career high rank of Juryo 13 and become a sekitori. Sadly he would win only four of his fifteen matches and was immediately demoted back down to makushita, he would never make it back to the salaried ranks again. In November 2012 with his stable master Fujizakura reaching the mandatory retirement age and closing down the stable he transferred to Azumazeki stable. In late 2013 Hiroki suffered a major right knee injury which would see him sit out for over a year and drop off the banzuke. He would return to the dohyo in January 2015 and start an impressive 22 win streak picking up two lower division yusho (Jonokuchi and Sandanme) in the process. After this though he would put up mediocre records having been troubled by a left ankle issue. After three consecutive losing records and losing his opening bout of the January 2017 basho he decided to retire.
