Carlos Toshiki

Toshiki began a job as a dishwasher at a restaurant, where he was paid less than average because he was Brazilian, but it was at the job where he began having opportunities. His boss asked him to sing for customers during breaks, and he gradually became known to the customers. One of the customers invited Toshiki to record commercial jingles. By 1985, after failed attempts to get into a record label and to develop his musical career, Toshiki decided that if he could not get a deal, he would move on with his life and get into a new career.[3]

While still working part time, he took vocal lessons and sung in commercial jingles, making a demo tape with songs in both English and Japanese and sending it to producers in hopes for more commercial work opportunities. One of the tapes were given to Koichi Fujita, a music producer. Fujita had wanted to continue Omega Tribe, which were in the middle of their final tour, and contacted Toshiki for an audition to become their new lead vocalist.[2]

In his audition, he was asked to sing covers of "Silence ga Ippai" and "Futari no Natsu Monogatari", ultimately passing the audition and being asked to become Omega Tribe's new vocalist of 1986 Omega Tribe. 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 "thousand" (千, sen) 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.[4] The single was an instant hit, and the band were able to complete two albums, Navigator in 1986 and Crystal Night in 1987, before one member, guitarist Teruka Kurokawa, left the band due to health issues.

The band's name was then changed to Carlos Toshiki & Omega Tribe, and the remaining members of the band were Toshiki, Shinji Takashima, and Toshitsugu Nishihara; American Joey McCoy would later join the group in November 1988. On August 10, 1988, the group released "Aquamarine no Mama de Ite," which peaked at No. 3 on the Oricon charts and is considered their signature song alongside "Kimi ha 1000%". After four albums, the group announced to the TV program Music Station that they would disband following a tour, officially breaking up on March 16, 1991.

After the disbandment, Toshiki started his solo career with the single "Yoakemade Borderless" in 1991, following up with his first solo studio album Emotion – Migigawa no Heart-tachi e that same year. In 1993, he released the album Alquimist and released Doushitedarou? a year later. In 1994, Toshiki released the single "Forever" under the name Toshiki Takahashi, and a year later, released three more singles and the album Shake It Down, all under TM Factory. The album would be his last album on a major record label since his debut on VAP in 1986.

In 1995, Toshiki suffered from a spinal disc herniation, and after an operation he decided to return to Brazil in 2000 to recover, retiring from music having had no intention to continue in Brazil in a different genre.[5] He became a restaurateur, running his parents' restaurant, before deciding to pursue a career in biotechnology and started working at a seed company. During his time as a restaurateur, he appeared on the Japanese show Anohitohaima!? in 2000.[6]

In 2012, he started attending a university in Brazil to studio biotechnology, eventually succeeding in developing garlic that was resistant to heat and diseases that otherwise would have prevented it being grown in Brazil.[7] It has been reported that nearly 100% of domestically produced garlic seeds were bought from Toshiki's company, with Toshiki being described as one of the "great garlic specialists" of Brazil.[8]

In 2016, it was announced that Toshiki would tour in Japan for the first time in 22 years, but the tour was postponed until 2017, where he returned to music with B-EDGE, a jazz band with some of the former members of Omega Tribe's backing band.[9][10] The next year, he toured again with the Turne do Japao 2018 and released his the album Nova Nostalgia, which featured self-covers of past Omega Tribe songs. In 2018, he joined as an official member of B-EDGE, leading the band as its main vocalist until 2019; the band was temporarily renamed to Carlos Toshiki & B-EDGE during his time as lead vocalist.[11] The band released the album Nova Nostalga in 2018, covering many of Toshiki's songs during the Omega Tribe era.[12][13]
