Visual kei , abbreviated v-kei , is a category of Japanese musicians that have a strong focus on extravagant stage costumes that originated in Japan during the early 1980s. Koji Dejima of Bounce wrote that visual kei is not a specific sound, but rather it "revolves around the creation of a band's unique worldview and/or stylistic beauty through visual expressions in the form of makeup and fashion". While visual kei bands can be of any music genre, it is generally associated with glam rock, punk rock, and heavy metal.
