"Comiket (コミケット Komiketto?), otherwise known as the Comic Market (コミックマーケット Komikku Māketto?), is the world's largest dōjinshi fair, held twice a year in Tokyo, Japan. The first Comiket was held on December 21, 1975, with only about 32 participating circles and an estimated 600 attendees. Attendance has since swelled to over a half million people."
