Dōjin music (同人音楽 doujin ongaku) also called otokei dōjin (音系同人) in Japan is a sub-category of dōjin activity. Dōjin are basically non-official self-published Japanese works which can be based on official products or completely original creations. Such products are sold online on specialized sites on the author’s own sites and in conventions such as the very popular Comic Markets.
