kosupure, short for "costume play",
is a Japanese subculture centered on dressing as characters
from manga, anime, tokusatsu, and video games, and, less
commonly, Japanese live action television shows, fantasy
movies, Japanese pop music bands, Visual Kei, fantasy music
stories (such as stories by the band Sound Horizon), and
novels. However, in some circles, "cosplay" has
been expanded to mean simply wearing a costume.
