Japanese pop culture is inscrutable but that doesn't mean it's not fun. Much revolves around fictional worlds in manga, anime and gaming. Those fictional worlds, sampled, become participatory in cosplay, fanfic, AMV, RPG, Plushie-kerade (in which stuffed toys are dressed in costumes and played as puppets by ninja clothed puppeteers), cosplay life size chess, and, of course, karaoke. This is an all ages event, strictly no hentai, yaoi or yuri.
Sometime I need to research trends in IP rights in Japan. Does otaku culture sampling and repurposing creative material create a stronger business model than the "sampling is death" position taken by the RIAA and MPAA? Especially since the sampling battle has been essentially won by the samplers.
Much information at the Kumoricon Website and a detailed schedule charting all times.
