Le phénomène du kûdôka © Alice Berthon‎

The Japanese notion of kūdōka 空洞化 (hollowing-out phenomenon) is usually employed to designate spaces or activities that face a hollowing-out process as part of social mutations. However, the substance of this notion varies considerably according to historical and social contexts. This study day will be an opportunity to reinterrogate the idea, discourses and representations of kūdōka by revisiting the phenomena and effects, both real and virtual, designated or provoked by this notion, without limiting ourselves to demographic, geographical and economic dimensions, but starting from the premise that these phenomena imply social, cultural or even artistic changes on both a national and international level, as well as territorial dynamics in contemporary Japanese society.
