Initially "cosplay" was a promotion strategy.
In the1980s, Tokyo Game Show was held in Japan. Some exhibitors wore costumes
and accessories to act as the characters from the games so as to get attentions
from audiences. They were called "Brand ambassador" in the
beginning. Later some animation-lovers imitated those "brand
ambassador" to wear customs in some private gatherings.
The Internet fosters the creation of social-networking
between animation-lovers. They share stories,news,photographs to each other.
They even have regular gatherings. This gradually increases the number of
participants in Cosplay activity. Cosplay is thus getting much more
popular. Finally Cosplay becomes an unique culture of Japan.
Cosplay is generally considered different from Halloween.It
is because wearing customs in Halloween is a tradition and activity to reflect
the culture. However the purpose of Cosplayers is to accurately copy the
characters. In order to replicate characters accurately, most of the customs
and accessories are made by the Cosplayers themselves. Apart from customs
and accessories some Cosplayers will pay much attentions on other details so as
to act as the characters such as body languages and dialogues.
