Japanese rock , sometimes abbreviated to J-rock , is rock music from Japan. Influenced by American and British rock of the 1960s, the first rock bands in Japan performed what is called group sounds, with lyrics almost exclusively in English. Folk rock band Happy End in the early 1970s are credited as the first to sing rock music in the Japanese language. Punk rock bands Boøwy and The Blue Hearts and hard rock/heavy metal groups X Japan and B'z led Japanese rock in the late 1980s and early 1990s by achieving major mainstream success.
