In Japan, obsessive adult fans and collectors of manga and anime are known as otaku. When the underground otaku subculture first emerged in the 1970s, participants were looked down on by mainstream Japanese society as strange, antisocial loners. Today otaku have had a huge impact on popular culture not only in Japan but also throughout Asia, Europe, and the United States. Hiroki Azuma's Otaku offers a critical, philosophical, and historical inquiry into thecharacteristics and consequences of this consumer subculture.
