Genshiken (Japanese: げんしけん) is a manga series by Shimoku Kio about a college club for otaku (extremely obsessed fans of various media) and the lifestyle its members pursue. The title is a shortening of the club's official name, Gendai Shikaku Bunka Kenkyūkai (現代視覚文化研究会), or "The Society for the Study of Modern Visual Culture". The series has also been adapted into an anime directed by Tsutomu Mizushima.
