Although he started learning the piano during his elementary school life, Kohei Tsukada quit this hobby when he began playing soccer. When he was a junior high school student, he was deeply impressed with game music and started playing and picking up the piano again by himself. During his high school days, he started composing music and became involved with bands. He quietly continued to compose music and write lyrics after he entered university even though the group had broken apart. In 2014, he set his mind on being a composer and, in 2015, he made his debut as a composer. His strong point is his musical approach in which he creates a new view of the world through the lyrics, composition and arrangement, and he always engages in music production by focusing on this approach.

His major works are: AKB48, SKE48, THE IDOLM@STER MILLION LIVE!
