After competing successfully in junior high school sumo he gave up formal education at the age of fifteen and entered the Takadagawa stable to pursue a professional career.

On his third tournament in the division, in January 2012, the seventeen-year-old Tatsu tied for the lead with six wins at the end of regular competition but was defeated in the first round of an eight-man play-off for the makushita championship.

[5] Tatsu spent the next two years performing consistently in the mid to upper makushita ranks before a run of eight consecutive winning records (kachi-koshi) saw him being promoted to jūryō (second division) for the November 2014 tournament.

A 10–5 record in September however, put him back in contention and an 8–7 in November 2015 (beating Satoyama on the final day) saw him promoted to makuuchi (top division) for the first time.

Kagayaki struggled in his top division debut: he won only two of his first thirteen matches, one of which was a walk-over when his scheduled opponent, Endō, withdrew with an injury.

After reaching as high as maegashira 3 for the November 2020 tournament, Kagayaki posted consecutive losing records, eventually being relegated back to jūryō for the January 2022 basho.
