The Comic Market (Comiket) is a marketplace where individuals can offer their own self-produced creations to a community that appreciates and supports such creative personal activities.
Comiket primarily focuses on acting as a communal exchange place for self-published books, known as dojinshi. Japanese dictionaries define dojinshi as self-published material aimed toward like-minded individuals and the Comic Market invites any publication (books, music, films, software, etc.) published by individuals that are not available through standard commercial outlets.
