Doujinshi

A self-published work created and distributed independently, often manga or prose and commonly produced by fans or creator groups in Japan.

Dōjin: A Japanese term for a group of people sharing an interest or pursuing creative work together. Doujinshi takes its name from these voluntary creator communities.
Dōjin circle: A small group or individual producing creative works under a shared name for independent distribution. Circles are the common organizational units behind doujinshi releases.
Meiji literary circles: Creative groups in Japan during the Meiji period that circulated literary work outside ordinary commercial publishing. These circles provide historical roots for the term’s independent-creator sense.
Parody: A work that imitates another work or style to expose, criticize, or play with its features. Parody is a common mode for reworking popular characters and stories.
Copyright in Japan: The legal framework governing rights to creative works in Japan, including reproduction and adaptation. Fan-made doujinshi often adapts copyrighted characters and settings.
Self-publishing: The publication and distribution of creative work by its creators, without a conventional publishing house. Independent production distinguishes doujinshi from publisher-issued manga.
Print-on-demand: A publishing method that produces copies in response to orders rather than printing a large stock in advance. Small print runs help creators manage uncertain demand.
Comiket history: The development of Comic Market, from its founding in 1975 into Japan’s largest doujinshi convention. Comiket’s growth made doujinshi exchange visible at national scale.
Original doujinshi: Independently published Japanese creative work using original characters and settings rather than borrowed properties. Not all doujinshi depends on fan-created continuations or reinterpretations.
Derivative work: A creative work based on or adapted from one or more pre-existing works. Many doujinshi are derivative works, though original titles also exist.
