Komatsu was chosen as one of the Designated Players for Development by J. League and JFA in 2005 when he was a student of Kwansei Gakuin University.

After graduating from university in 2006, he officially signed with Cerezo. On 12 August 2006, he made his J. League debut in a 1–0 loss against Omiya Ardija. Two month later, he loned out to Kyu-League side V-Varen Nagasaki.
He returned to Cerezo for the 2007 season and his first goal for the club in a 3-1 win against Mito HollyHock, on May 23. During the 2007 season, he managed to form a strike partnership with fellow striker Tatsuya Furuhashi, as the pair scored a total of 30 goals between them.
