RADWIMPS is a Japanese rock band consisting of Yojiro Noda on vocals, guitar, and piano, Akira Kuwahara on guitar, Yusuke Takeda on bass, and Satoshi Yamaguchi on drums, who debuted independently in 2003 and later on major label in 2005.

In 2009, Satoshi Yamaguchi went into an indefinite break due to focal dystonia, a chronic disease, and the band has since remained a trio.
