LUNA SEA are a rock band formed in Kanagawa, Japan in 1989. The band was founded by bassist Jun "J" Onose and rhythm guitarist Kiyonobu "INORAN" Inoue when they were in high school, and was originally known as LUNACY. When the senior members graduated from school in 1989, LUNACY recruited lead guitarist and violinist Yasuhiro "SUGIZO" Sugihara, drummer 真矢 (SHINYA, born Shinya Yamada), and vocalist RYUICHI (Ryuichi Kawamura, then called "Rayla"), a lineup that has remained the same since then.
