Ohayocon is a three-day anime convention held annually in January or February at the Dayton Convention Center in Dayton, Ohio. The convention’s name is a playful nod to its home state—”Ohio”—and the Japanese word ohayou (おはよう), meaning “good morning.” Celebrating anime, pop culture, cosplay, and community, Ohayocon is proud to be the longest-running anime convention in Ohio.
