Comiket Girls 2011, Tokyo, Japan

Time, date, and location
Comic Market is held twice a year; once in August, and once in December. These are typically referred to as NatsuComi (夏コミ Natsukomi) and FuyuComi (冬コミ Fuyukomi) (contractions of Summer and Winter Comiket) respectively. NatsuComi is three days long, and usually is held during the weekend around August 15. FuyuComi is two to three days long, and usually is held between December 28 and 31. The current convention location is the Tokyo Big Sight convention center near Ariake, in Odaiba, Kōtō, Tokyo. The major part of the convention runs from 10AM to 4PM, though the company booths run all the way until 5PM. On the last day of the convention, the company booths and Cosplay Square close an hour earlier, at 4PM and 3PM respectively. Due to the popularity of the event, the official Comic Market website advises first-time attendees to arrive in the afternoon to avoid having to wait in line. Those arriving at 10AM can expect to wait in line for about an hour before being able to enter. Attendees who arrive on the first train, can expect to wait about five hours before entering at roughly 10 or 10:30AM.
The last Comiket, Comiket 80, was held on August 12, 13 and 14, 2011.
