It would take him over four years rising slowly through the lower divisions before reaching the professional ranks of jūryō.

[1] During this time, in 2011 he and his brother's family home was lost in a fire and they agreed building their parents a new house could be motivation for them to achieve more success in sumo.

Chiyomaru admits that the indignity of being his own brother's attendant did motivate him and he might not have achieved promotion if this hadn't happened.

In his debut at this level, he defeated several makuuchi veterans and accumulated an 8–4 record on the 12th day before losing his last three bouts to end at 8–7.

In March 2018 he reached his highest rank to date of maegashira 5, but five consecutive make-koshi or losing records saw him relegated to the jūryō division after the November 2018 tournament.

In November he recorded a 9–6 score, losing to Shimanoumi on the final day preventing him from achieving double digit wins for his first time in the top division.

He withdrew from the March 2020 tournament in Osaka, held without spectators due to the coronavirus outbreak, with a fever on Day 8.

"[11] In 2014, a photo of him taking a nap, which was posted on the Japan Sumo Association's official Twitter account, became an internet hit.

[12] In March 2015 he shook hands with Derek Jeter who was visiting the Osaka tournament, but admitted not knowing who the retired Yankees star was.
