Fan service (ファンサービス, fan sābisu?), sometimes written as a single word, fanservice, is a vaguely defined term chiefly used for Japanese visual media—particularly in anime fandom—to refer to elements in a story that are unnecessary to a storyline, but designed to amuse or sexually excite the audience. It is also sometimes referred to in Japan as a service cut (サービスカット, sābisu katto?) or simply service (サービス, sābisu?). The term can be applied more generally to something that is done solely to please fans.
