Japanese rock (Japanese: 日本のロック, Hepburn: Nihon no Rokku), sometimes abbreviated to J-rock (ジェイ・ロック, Jei Rokku), 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.[1]
Rock bands such as B'z and Mr. Children are among the best selling music acts in Japan. Rock festivals like the Fuji Rock Festival were introduced in the late 90s with attendances reaching a peak of 200,000 people per festival making it the largest outdoor music event in the country.[2][3]
