the brilliant green is a Japanese rock band from Kyoto formed in 1995. The group became active under Sony Music Entertainment Japan and made its major debut with "Bye Bye Mr. Mug" in 1997. That release marked the start of their career in the mainstream Japanese music industry and established the band as a long-running presence in rock.
Over time, the brilliant green remained centered on its core identity as a Kyoto-born Japanese rock band, with a career shaped by label changes and a stable lineup history. Their work during the Sony years defined the foundation of their public profile, while "Bye Bye Mr. Mug" continues to serve as an important reference point for listeners discovering their early catalog.
Their contract with Sony ended in 2008, and on December 1, 2009, the band announced that it had signed with Warner Music Group Japan. That transition marked a new chapter for the group after more than a decade of activity and kept the band connected to a major-label path in Japan.
