The 22-year-old, who began his career at Cerezo after dropping out of Hongik University, has signed a three-year deal with the club pending a work permit, although he will only start training with the Bluebirds once he finishes playing for his country at the London Olympics.
Kim has been dubbed by national team coach Choi Kang-hee as the long-term successor to former Manchester United midfielder Park Ji-sung, and has already won 14 caps for the senior side.
In a statement released on Cerezo's official website, the player expressed his gratitude to the Japanese side for the role they played in his development.
"I learned many things at Cerezo," he commented. "I was able to play hard because all of you supported me, and I'll never forget my time at Cerezo."
Kim is the second key player to leave the Nagai Ball Gall Field this summer, after midfielder Hiroshi Kiyotake left for Bundesliga outfit Nuremberg.
