Biography

Seto Koji discovered his interest in acting when he saw his idol Satoshi Tsumabuki in the drama Orange Days (2004). Shortly after, at fifteen years, his mother enrolled him in the local Acting School Himawari in Fukuoka City where he was taught in drama, dance and music. He got his first part after one year in training in the comedy drama Rocket Boys as the main antagonist of later D-BOYS fellow members Yuya Endo and Kotaro Yanagi. Afterwards, on 31 July 2005, he participated in Watanabe Entertainment's official 2nd D-BOYS audition and won the Grand Prix 2nd Winner Award. He debuted as D-BOY in December 2005 at his first D-Live event - an entertainment show featuring only D-BOYS members. In Spring 2006, at just seventeen, he moved from his hometown in Fukuoka prefecture to live by himself in Tokyo and starred with other D-BOYS members in their first own TV production "DD-BOYS".
