Miyabiyama competed in amateur sumo tournaments while at Meiji University, but left before graduation to join the professional ranks.

He quickly worked his way through the ranks, logging in four consecutive championships, two in makushita and two in jūryō to reach the top makuuchi division in March 1999 just eight months after entering professional sumo.

Sakaigawa-oyakata (former yokozuna Sadanoyama), in particular, was reported to have felt it was too soon as Miyabiyama had only been in makuuchi for just over a year, and had not yet won a top division title.

[1] In the end the doubters were proved correct as Miyabiyama lasted just eight tournaments in the rank, never scoring more than 9 wins, before being demoted in the wake of two consecutive losing records.

In January 2003 he looked to have earned his first ever kinboshi or gold star and to have defeated yokozuna Takanohana for the first time in eleven attempts with a rare counter-attacking nichonage throw but although the referee declared him the winner the judges ordered a rematch, which he lost.

He produced the occasional strong tournament, finishing as runner-up in July 2004, and he held a san'yaku rank several times, but he was unable to go further and continued to move up and down the banzuke.

In May at sekiwake rank he produced a superb 14–1 record, only losing the championship on the last day in a playoff to then-ōzeki Hakuhō.

There was speculation that another strong performance in July 2006 would see him return to ōzeki, but he got off to a poor start, winning only three bouts in the first seven days, and though he recovered somewhat to post a 10–5 score, it was not considered good enough.

Miyabiyama fought in the top division for 82 tournaments in total, which is second best among makushita tsukedashi entrants and the eleventh best overall in sumo history.

His danpatsu-shiki, or official retirement ceremony, was held at the Ryōgoku Kokugikan on February 1, 2014 with around 8,000 in attendance and 270 guests taking part in the hair-cutting before his topknot was removed by his former stablemate Musōyama, now Fujishima Oyakata.

Miyabiyama was married in 2008 to a 24-year-old former office worker from Kurume, Fukuoka, and their wedding reception was held in June 2009 with 450 guests including his stablemaster Musashigawa Oyakata attending.
