International Otaku Expo Association

The International Otaku Expo Association (IOEA), stylized as I.O.E.A, is an international cooperative association of otaku fan event organizers from around the world. The term otaku is used to indicate enthusiasm for Japanese pop culture and subculture surrounding anime, manga, games and fashion. The association does not limit membership to events that focus solely on Japanese culture. Any association that wishes to embrace otaku culture, whether it be Japanese or non-Japanese, is welcome to apply for membership with the IOEA.

As of July 2023 the IOEA currently has over 123 member events around the world, in 46 countries/regions in every continent except Antarctica.

History
Fans of anime and manga have been networking with each other since the 1980s. Osamu Tezuka had visited the American fan organization Cartoon/Fantasy Organization in the 1980s.

Since at least 2007, Comic Market staff have been discussing about the many international visitors that have been attending Comic Market through the years which also included foreign press.

Discussions among numerous fan events for a cooperative association started prior to Comic Market's 2015 Comiket Special 6 Otaku Summit, an event that invited many otaku events from around the world. While numerous parties were involved in the creation of the IOEA. Takamasa Sakurai, Kazutaka Sato, and Dan Kanemitsu (Japanese Wikipedia Entry) were the original planning group.

The IOEA was formally established on March 27, 2015 during Comiket Special 6 Otaku Summit held in Makuhari Messe, Chiba.
