Cosplay (, kosupure?), a portmanteau of the English words "costume" and "roleplay", 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, or Japanese pop music bands. However, in some circles, "cosplay" has been expanded to mean simply wearing a costume.
In Japan, "cosplay" as a hobby is usually an end unto itself. Like-minded people gather to see others' costumes, show off their own elaborate handmade creations, take lots of pictures, and possibly participate in best costume contests.
The most specific anecdote about the origin of the word "cosplay" was that Nov Takahashi (from a Japanese studio called Studio Hard) coined the term "cosplay" as a contraction of the English-language words "costume play" while he was attending the 1984 Los Angeles Science Fiction Worldcon. He was so impressed by the hall and masquerade costuming there that he reported about it frequently in Japanese science fiction magazines. This point is debatable, however, as the word fits in with a common Japanese method of abbreviation: combining the first two syllables of one word with the first two syllables of a second word (or, more precisely, the first two moras of each). Other examples of this include Pok?mon
Cosplay trends A recent trend at Japanese cosplay events is an increase in the popularity of non-Japanese fantasy and science fiction movie characters, perhaps due to the international success of such films as The Matrix, Star Wars and Lord of the Rings. Characters from the Harry Potter films have a particularly high number of female fans in Japan, with female cosplayers playing either male or female characters, Draco Malfoy being an extremely popular choice.
The act of cosplaying as characters of the opposite sex is called "crossplay" (cross-dressing cosplay). A small niche group in this field are dollers, a subset of kigurumi cosplayers; usually male, they wear bodysuits and masks to fully transform into female characters.
Another recent trend in cosplay is a blurring of the distinction between costumes based on characters from games and anime, and "original" costumes based upon a general theme or existing fashions. In particular, the Tokyo teen-fashion trend of Gothic Lolita has attracted some cosplayers who might not have the inclination (or possibly courage) to wear such distinctive clothes around town, but who would like to dress in such a manner on some occasions.
