Kōji Tosa (土佐浩司, Tosa Kōji, March 30, 1955) is a Japanese retired professional shogi player who achieved the rank of 8-dan.^[2]

In March 2017, Tosa finished the finished 75th Meijin Class C2 league play (April 2016 – March 2017) with a record of no wins and 10 losses, earning a second demotion point which meant he was only one point away from automatic demotion to "Free Class" play.^[6] As a result, he declared his intention to the Japan Shogi Association to become a Free Class player as of April 2017 rather than risk automatic demotion.^[7]

On June 8, 2020, the Japan Shogi Association announced on its website that Tosa had retired from professional shogi. His official retirement date was given as May 14, 2020.^[8] Tosa retired with a career record of 666 wins and 728 losses for a winning percentage of 0.478.^[1]
