Kikkawa Koji, born in Hiroshima, is a Japanese musician.

He was supposed to represent Japan in water polo in the coming Olympics but chose to be a singer. His music career began on February 1, 1984, with "Monica" (later remade in Cantonese sung by Leslie Cheung) and he won 8 music awards in the same year. After taking a short break in 1988, he came back as a lead singer in the band Complex with Tomoyasu Hotei (former guitarist of Boøwy), and "Be My Baby" was released. Complex remained as one of the most popular bands in Japan until 1990.

After "Complex", Koji released series of hit singles such as "Setsunasa o Korosenai", "Kiss ni Utarete Nemuritai" and "Boy's Life". Koji completed a "20th Anniversary Tour" at Budokan on February 1, 2005. In 2006 he recorded "One World," the theme for the 2006 motion picture Kamen Rider Kabuto: God Speed Love. He had teamed up with popular Japanese DJ TWINS to release a single "Juicy Jungle". Also, DJ TWINS had released an album with remixes of several of Koji's previous hits.

With this new sound-disco revisit, Koji redefined himself like he does year after year. Throughout his career, it could be considered that Koji had outgrown from an idol to an artiste that explores the music boundary. He writes his own songs, produced and arranged his own albums, and played most of the instruments. Edit Biography
