Early Life[]
Kodai Ota was born on August 30, 1992, in Okazaki, Aichi. He began sumo wrestling when he was six years and was trained by his father. He attended Aikodai Meiden High School where he was a member of the school's sumo club. In his second year of high school, Ota and his school finished second at the Inter-High School Team Competition, losing to the powerhouse Saitama Sakae in the finals.[1] After high school, he enrolled at Doshisha University and was a member of the school's sumo club as well.

Career[]
He made his professional debut in March 2015 and was given the shikona "Hirotsukasa" (大司). In March 2015, he was aiming for the sandanme yusho and won his first six matches before losing his final match to Kiribayama. He was promoted to makushita in May 2016 and had not posted a single losing record at the time. He injured his knee in his first match in makushita against Oyanagi and had to withdraw from the tournament.[3] As a result he was demoted back down to sandanme, but he returned to makushita in September 2016.
