1986 Omega Tribe

During the disbandment of S. Kiyotaka & Omega Tribe, Koichi Fujita sought to create the next iteration for his Omega Tribe project: 1986 Omega Tribe became that successor. This new version of the group consisted of Shinji Takashima and Toshitsugu Nishihara, the existing guitarist and keyboardist, Mitsuya Kurokawa, former touring member for Momoko Kikuchi, and lastly Carlos Toshiki who had impressed Fujita during a impromptu vocal audition. In addition to the group's name and member lineup being changed, many of its composers and writers had departed when Kiyotaka Sugiyama left.

The group's debut single, 君は1000%, was a smash hit and foreshadowed their massive success both on and off the Oricon charts. Between 1986-1987, they release two albums, seven singles, and one DJ Special. The second phase of the Omega Tribe legacy would eventually, however, undergo another round of changes. Kurokawa, Fujita's declared "bandleader", departed the group due to health reasons during the early production of Down Town Mystery. Around this time, it was decided to change the group's aging name, and debut again as Carlos Toshiki And Omega Tribe; to further shine more spotlight on Carlos.
