Speaking to reporters after the 9th day of the September 2011 tournament, he quipped, "Let me tell you I was called Gaga since the time I was born.

A 6–9 record in September 2018 left him in danger of demotion to makushita for the first time since he became a sekitori in November 2009, and Gagamaru told reporters he would consult his stablemaster before deciding whether to continue wrestling.

He spent the rest of 2019 in jūryō but pulled out of the November tournament on Day 13 with only one win, ensuring demotion to makushita again.
