In 1985, Kōmoto joined with
Masatoshi Mashima to form The Blue Hearts and released their first single (
Hito ni Yasashiku) and their major debut (
Linda Linda) in 1987. After The Blue Hearts took a break from studio work and touring in 1994, Kōmoto started working on a solo album which was never released. In 1995, Kōmoto and Mashima joined to form Happy Song Co., Ltd. When the band officially broke up on June 1 of that year, they also formed a new band,
The High-Lows. The new band released its first single (
Missile Man) and a self-titled album on October 25. A couple of years later, Kōmoto and Mashima finished building their own studio, Atomic Boogie Studio. The High-Lows eventually broke up in 2005. Kōmoto continued solo studio work in 2006 and released two singles on July 5,
Manatsu no Sutoreeto and
Tengoku Umare. He played all of the instruments for the song, including guitar, bass, and drums. He again joined with Mashima later in the year and performed at a rock festival on July 23, marking the official beginning of
The Cro-Magnons. They released their debut single,
Tallyho, on September 20. == Personal life ==
