Okumoto was born in Osaka, Japan, in a family where music was an obligatory part of a child's education. He took piano lessons from ages 3 to 13. At 15, he dropped out of school to take his first professional job at the Live House in Osaka. A year later he moved to the big city -- Tokyo. From 1975 to 1980 he played night clubs and recording sessions both as a house band keyboardist and as a "real" member in a number of Japanese rock groups. The most popular was Creation, with whom he recorded his first album as a group member in 1978. While Creation's profile was rising, Okumoto also appeared on Kitaro's In Person LP and its accompanying tour. Kitaro's record label, Canyon, offered the young keyboardist a contract for three albums that were all delivered and released in 1980: Solid Gold, Makin' Rock, and Synthesizer. Recorded in London, Hollywood, and Tokyo, respectively, they featured an impressive cast of musicians, including David Foster and Toto guitarist Steve Lukather.
The LPs did not garner the interest (critical or popular) Okumoto was hoping for and, disenchanted, he decided to move to Los Angeles where he spent the next four years studying at the Dick Grove School of Music. His discography and live schedule picked up after his graduation in 1984. During the next 13 years, he has played the role of an adaptable sideman, performing with retro-R&B groups, pop sensations, and hard rock bands while recording with Homer, Earthshaker, Kuni, and Edwing, among other acts that didn't last long. In 1996-1997 he tried to earn a living in easy listening, producing three volumes of the Treasured Moments series and a couple of movie scores.
Meanwhile, in 1995, Okumoto met the Morse brothers and joined their group Spock's Beard, which had just released its first self-produced debut, The Light, and connected him back to his roots. The group's popularity among prog rock fans rose one notch with 1997's Beware of Darkness (the first album with the keyboardist on board) and crossed over to a wider audience with the release of The Kindness of Strangers in 1998, following the group's signing with the label Metal Blade. Since 1998, Okumoto has been working almost exclusively with Spock's Beard. He released Coming Through, his first solo album in over 20 years, in late 2002. ~ François Couture, Rovi
