Ohayocon's name is derived from the similarity between "Ohio", the convention's location, and Ohayou (おはよう), which means "good morning" in Japanese.

[1][5][6] The convention typically offers an anime music contest, an artists' alley, concerts, costume contests, a dealers' room, a formal ball, a masquerade, musical events, panel discussions, a rave, table-top games, tournaments, video gaming, and workshops.

[1][6][7][8][9][10][11] In 2007, the Midwest premiere of Robotech: The Shadow Chronicles occurred at the Arena Grand Theatre during Ohayocon.

This was due to the firing of the conventions chair and head of marketing over a logo dispute, among other issues including finances.

The staff, as part of the Conventions of Ohio Volunteer Event Network (COVEN), attempted to negotiate unsuccessfully with CESI.
