Ohayocon is a convention focusing on Japanese pop culture, including popular anime and manga fandom. It is traditionally held during the month of January in Columbus, Ohio. Ohayocon was first held in 2001 in Cleveland, Ohio, moving to Columbus in 2003. Ohayocon derives its name from the similarity in pronunciation between "Ohio", where the con is held, and Ohayo(おはようOhayou), which is Japanese for "Good morning". With its continued growth, Ohayocon has become the largest winter anime convention in North America.
