上海アリス幻樂団
Many derivative works based on "Touhou" have been created since the release of "Embodiment of Scarlet Devil", including dōjinshi, dōjin music (many of the songs had been made remixing the original games' music), dōjin anime, and dōjin games (even though the "Touhou" games themselves are dōjin games). The vast scope of "Touhou" derivatives prompted commentary, noting that "Touhou Project" became an unmissable aspect of Japanese consumer generated media. These dōjin activities are mostly responsible for adding original attributes to characters that ZUN may not have intended. ZUN, for the most part, had acknowledged, appreciated, and even encouraged these derivative works by imposing very few restrictions on the use of his works. The major restrictions are on unauthorized commercial distribution (as opposed to dōjin) and the spoiling of endings; proper attribution to Team Shanghai Alice is a requirement. ZUN stated himself that he did not want the "Touhou Project" game series to be officially commercialized.
