ZUN (video game developer)

Jun'ya Ōta (太田 順也, Ōta Jun'ya), known professionally as ZUN, is a Japanese video game developer and composer, known for creating the Touhou Project bullet hell shoot 'em up video game series through his one-man doujin group Team Shanghai Alice.

ZUN developed the first five Touhou Project games for the Japanese NEC PC-9800 computer series, with the first, Highly Responsive to Prayers, released in August 1997; the series' signature danmaku mechanics were introduced in the second game, Story of Eastern Wonderland (also 1997). The release of Embodiment of Scarlet Devil in August 2002 marked a shift to Microsoft Windows. Numerous sequels followed, including several spin-offs departing from the traditional bullet hell format. He has also collaborated with other circles to produce related print works and music albums.

Touhou Project has become more particularly notable as a prominent source of Japanese dōjin content, with the series spawning a vast amount of fan-made works such as artwork, music, print works, video games, and Internet memes. Because of this, it has gained a large cult following outside of Japan. In 2010, the Guinness World Records called the Touhou Project "the most prolific fan-based shooter series" ever created. The popularity of the series and its derivative works has been attributed in part to the few restrictions placed by ZUN on the use of his content. ZUN is also known as the Hakurei Kannushi (博麗神主), which is also the name he uses for his Twitter account.
