Comiket Girls 2011, Tokyo, Japan

The Comiket website usually has a list of stores (by prefecture) where you can order the catalog. Please be aware that not all stores have the CD-ROM version and some may not have the print version. This is also on the list of stores on the Comiket homepage. Catalogs can be ordered from overseas, depending on the store. The catalog typically comes out two weeks before the convention, up until the first day of Comiket.
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.
