1985–1986: Formation and debut as 1986 Omega Tribe Toshiki was a
Japanese Brazilian who was working part-time in Japan as a dishwasher and had made demo tapes with covers of English-language songs that were distributed to various companies, one of them being given to Fujita. Fujita invited Toshiki and asked him to cover "Futari no Natsu Monogatari" and "Silence ga Ippai" for an audition, and after practicing, passed the audition at VAP's recording studio and was chosen as Omega Tribe's new vocalist. After Toshiki was made the vocalist of a new group, Fujita had guitarist Shinji Takashima and keyboardist Toshitsugu Nishihara, both previously part of S. Kiyotaka & Omega Tribe, join the band. He also hired guitarist Teruka Kurokawa, who was part of
Momoko Kikuchi's backing band and made him the
bandleader. To help Toshiki get into the aesthetic of the band, as well as to get to know him better, Fujita took him to
Hawaii. During the trip, Toshiki commented on the similarity between the Japanese word for and the Portuguese word for "hundred" (cem), which Fujita also found interesting, contacting a lyricist to create a song based on the pronunciations. The song would become 1986 Omega Tribe's debut single, "
Kimi ha 1000%", which Toshiki sang without understanding most of the lyrics. The album featured a
swordfish on the cover, which became a symbol of the band during the 1986 era, as well as having "resort-like lyrics" for the new era of Omega Tribe. On August 7, 1986, the band released their second single, "Super Chance", which was written by lyricist
Masao Urino charted at 2nd place on the Oricon Singles Chart. The band started production on their second album,
Crystal Night near the end of 1986, with the production team showing an interest in electric sounds based on American black
contemporary music, releasing the album on February 4, 1987. The band released their final album,
Natsuko on July 25, 1990, their only album after their transfer to Warner Pioneer. During the production of
Natsuko, there was a dissonance between the production team and the members, as well as between the members themselves. Fujita and Toshiki disagreed about the selection of songs that would be in the album, with Fujita eventually leaving most of the production to the members, especially Toshiki. On December 14, 1990, the band announced that they would be disbanding following a final tour that began on February 21, 1991, disbanding after the tour's final performance on March 16, 1991. They released one album,
Nova Nostalgia (2018), which featured covers of Omega Tribe songs from his era as the vocalist. On February 24, 2021, VAP released the compilation album
To Your Summertime Smile for the band's 35th anniversary which included remixed versions of 1986 Omega Tribe songs. == Band members ==
