Apprentice professional[]
Koga entered the Japan Shogi Association's apprentice school in September 2011 as a protegee of shogi professional Isao Nakata.[2][3] He was promoted to the rank of apprentice professional 3-dan in April 2017 and obtained full professional status and the rank of 4-dan after finishing third in the 67th 3-dan League (April 2020 – September 2020) with a record of 13 wins and 5 losses.[2][3][4][5] Although Koga's third place finish was not sufficient to earn him direct promotion to 4-dan, it was good enough to earn him a second promotion point which gave him the option to enter the professional ranks as a free class player. After consulting with his mentor Nakata, Koga decided he wanted to turn professional even if it meant starting in the Free Class.[2][3][a]
