He was present on Static-X's debut album, Wisconsin Death Trip, but left the band prior to the recording of their second album, Machine, citing personal problems due to excessive touring. However, he did still contribute keyboards to the record. He rejoined Static-X after the firing of their then-current guitarist, Tripp Eisen, at the end of the recording process of the 2005 album Start a War, and was present to record their fifth album, Cannibal.
Between his stints in Static-X, he formed another, less aggressive band called Revolve. Drawing comparisons to Tool and Pink Floyd, they were very successful locally and played several concerts in and around the Los Angeles, California area. They released several demos as free downloads on their website, and released one EP containing several reworked versions of previously released demos, as well as a few new tracks. Koichi Fukuda has a son named Naoki Fukuda, born on August 8, 2008.
