Animegao kigurumi is a type of masked cosplay that has its origins in the official stage shows of various Japanese anime but has also been adapted by hobbyists. In Japan, most performers refer to this kind of cosplay as kigurumi (着ぐるみ) instead of animegao (アニメ顔, meaning anime face), which has been used overseas in order to differentiate the cosplay from the onesies sharing the same name. The term doller had also been used when referring to kigurumi cosplayers, but today mainly refers to BJD-styled masked cosplays. Although kigurumi remains a minor part of Japan’s cosplay scene, it began attracting overseas attention in North America and Europe around 2005.
