Founded in 1994, Otakon is an annual convention held in the summer months to celebrate Asian pop culture (anime, manga, music, movies, video games, etc) and its fandom. The event runs from Friday to Sunday and is packed with a schedule that has tons to do.
Starting in 2017, Otakon will be held at the Walter E. Washington Convention Center in our nation’s capital of Washington, DC.
All of this is run by the non-profit organization Otakorp, Inc.
