Comiket Girls 2011, Tokyo, Japan

As of 1982, there were less than 10,000 attendees at Comiket, however, by 1989, there were over 100,000 attendees. Approximately 35,000 sellers, known as circles, participated in Comiket as of 2001. An estimated 510,000 attendees converge in the course of three days, but this number continues to increase. Because of the extreme number of people gathering in a single place, mobile phone companies set up temporary antennas that are usually employed when stationary antennas are out of service. Area hotels, trains, and bus services also make special arrangements to accommodate the large crowds. Comiket 76 from August 14–16, 2009 attracted an estimated 560,000 attendees.
