Doujin (同人), also romanized as dōjin, is the Japanese term for a group of people who share an interest, activity, or hobby. It is sometimes translated into English as clique, fandom, coterie, society, or circle (as in sewing circle). Doujin also extends to self-published creative works produced by these groups, including manga, magazines, novels, music (doujin music), anime and video games (doujin soft). Print doujin works are collectively called doujinshi.
Doujin works are typically amateur and derivative in nature, though some professional artists participate in doujin culture as a way to publish material outside the regular publishing industry.
Annual research by the research agency Media Create indicated that of the US.65 billion of the otaku industry in 2007, doujin sales made up 48% (US million).

Doujin refers to self-published or independently produced works in various creative mediums, including manga, anime, music, games, and literature. Originally emerging in Japan, doujin encompasses a wide range of fan-made and original creations that often explore alternative or derivative aspects of existing popular culture. These works are typically produced and distributed outside of mainstream commercial channels, allowing creators to express their creativity, share their ideas, and connect with like-minded enthusiasts.
