Comic Market (コミックマーケット, Komikku Māketto), more commonly known as Comiket (コミケット, Komiketto) or Comike (コミケ, Komike), is a semiannual doujinshi convention in Tokyo, Japan.

[3] Approximately 35,000 circles (a term for groups or individuals who create doujin) participate in each edition of Comiket.

[5] The most common item sold at Comiket is doujinshi (self-published comics, novels or magazines), while a smaller number of circles sell doujin soft, analog (board/card/etc.)

These are often derivative fan works based on anime, video games, and other media, legal according to Japanese law (shinkokuzai).

[3] Some general contemporary guidelines include not wearing clothes that are too revealing, not imitating uniformed officers, and being out of cosplay when arriving/departing from Comiket.

This includes both large commercial companies, such as video game studios and manga publishers, as well as celebrity meet and greet sessions.

[1] Comiket is the largest fan convention in the world,[21] growing from fewer than 10,000 attendees in 1982[22] to over half a million by 2004.

[23][b] Because of the extremely high volume of attendance at Comiket, mobile phone companies set up temporary antennas, while the Tokyo Metro makes special arrangements to accommodate the large crowds.

[3] Since 2007, ComiketPC has worked with the Japanese Red Cross Society to organize bloodmobiles at Comiket events, with donors given Comiket-exclusive posters depicting characters from anime and video games.

Comiket would change locations frequently throughout the late 1980s and 1990s, as the Japanese bubble economy led to an upsurge in trade shows that made it difficult to secure a consistent venue.

The murders by Tsutomu Miyazaki and subsequent moral panic against otaku would lead to further difficulties in Comiket's ability to secure a venue.

[41] Affectionately nicknamed "Kuroket", the event hosted approximately 2,400 circles producing Kuroko's Basketball items.

As the east wing of Big Sight closed in 2019 for renovations in advance of the Olympics, the corporate booths of C96 and C97 were moved to Aomi Exhibition Hall, and both events expanded to four days of programming.

A virtual event titled "Air Comiket" was held in December to replace its originally planned dates.
