A doujinshi convention is a type of event dedicated to the sale of doujinshi, or self-published books (typically mangas, collections of illustrations, or novels). These events are known in Japanese as doujin sokubaikai (同人即売会, 'doujin sale event') or doujinshi sokubaikai (同人誌即売会, 'doujinshi sale event'). Thousands of doujinshi conventions take place in Japan every year. Doujinshi conventions can also be found in some other countries.
