Comiket Girls 2011, Tokyo, Japan

Problems related to Comiket
As the number of circles participating and number of participants increase rapidly, the event has become very crowded. In order to buy their favorite items (and especially famous items, such as dōjinshi from famous authors or special limited-edition items), thousands of people line up outside the Tokyo Big Sight convention center days before the event starts, causing serious security problems. Hence, in recent years lining up before the day Comiket is held on has been prohibited.
