Query: Serious ethnography of Japanese popular culture

This is a great collection by some of the outstanding contemporary specialists on Japanese popular culture. It is a serious ethnographic collection about popular culture and the dynamics of "fandom" across sports, manga and anime, popular music, and sumo, among other things. It sets a high standard for studies of popular culture in Japan and elsewhere. Highly recommended both for fans and observers of Japanese trends.
