In an attempt to observe and explore the ways in which individuals react to spontaneous cook-out situations, we launched the ‘Curry Caravan’ project in March 2012. Since then, we visited more than 70 towns in Japan, and cooked curry in various public spaces. Traditionally, there were ‘common’ places between public and private places. A ‘common’ place belongs to no one, and at the same time, it can be used and shared by everyone. A joint process of cooking is a way to creatively and loosely blur the distinction between public and private, and thereby promote ones ideas about togetherness. Though spontaneous, ad hoc and temporal, we suggest that ‘Curry Caravan’ plays an important role in reclaiming our ‘common’ places.
