Despite the opposition of his parents, he was persuaded by the former sekiwake Aonosato, then the head coach of Tatsutagawa stable, to give professional sumo a try and he made his debut in November 1992.

He reached the second jūryō division in January 1998, fighting under the shikona, or ring name, of Kaigatake, but he lasted only one tournament there.

He made his first winning score in the division in March 2001, but after suffering from a hernia he was demoted back to jūryō and had to miss the September 2001 tournament.

He became the oldest wrestler to win the makushita title at 34 years, one month (a record broken in May 2017 by Ōiwato [ja]).

Jūmonji was one of 23 wrestlers found guilty of fixing the result of bouts after an investigation by the Japan Sumo Association and he was forced to retire in April 2011.

His most common winning kimarite was a straightforward yori-kiri or force out, which accounted for roughly 40 percent of his victories at sekitori level.
