Flipper's Guitar (フリッパーズ・ギター) were a Tokyo-based rock band led by Keigo Oyamada and Kenji Ozawa. The band were influenced by the chirpy sound of British 80s pop and post-punk groups like Haircut 100, Exhibit B, Orange Juice, The Style Council and Aztec Camera, as well as the fashionably eclectic sounds of early 90s Britain, from alternative dance to acid jazz.

Keigo Oyamada , also known by his moniker Cornelius , is a Japanese musician and producer who co-founded Flipper's Guitar, an influential Shibuya-kei band, and subsequently embarked on a solo career. In 1997, he released the album Fantasma, which landed him praise from American music critics, who called him a "modern-day Brian Wilson" or the "Japanese Beck". In 2007, Rolling Stone Japan named two of Oyamada's albums amongst the "100 Greatest Japanese Rock Albums of All Time", with Fantasma ranking in 10th place and Camera Talk by Flipper's Guitar ranking in 35th place.
