Koki Kumasaka (熊坂 光希, Kumasaka Kōki, born 15 April 2001) is a Japanese footballer who plays as a defensive midfielder for Kashiwa Reysol.
Club career
University football
Enrolled at the Tokyo International University, he helped his side to second place in the Kanto University Division 1 League.[2] With four goals and two assists, he was named in the best XI for the league.[2]
Kashiwa Reysol
Having already played for them for six years during his youth, Kumasaka committed to re-join J1 League club Kashiwa Reysol in July 2023.[3] He made his professional debut in Reysol's 1–1 J1 League draw against Albirex Niigata on 30 March 2024, and went on to appear in the next three matches.[4] An injury during the Chibagin Cup limited his playing time, and his debut season was not seen as successful.[5]
After ten league appearances in 2024, Kumasaka remained in the first team the following season, featuring in Reysol's pre-season preparation before playing ninety minutes in their opening J1 League fixture against Avispa Fukuoka.[6] Following the appointment of Spanish manager Ricardo Rodríguez in February 2025, Kumasaka began to feature a lot more in the Kashiwa Reysol first team, forming a partnership with Riki Harakawa.[7][8] In March of the same year, he changed his contract type from Pro C to Pro A, having played 450 minutes in the J1 League.[9]
International career
Without having previously represented Japan at youth international level, he was called up to the senior squad in May 2025.[10]
Style of play
A volante, Kumasaka is noted for his ability in one-on-one duels, as well as his agility despite his height, standing at 1.85 metres.[11]
