The contemporary urban paradigm has started to focus the capabilities of urban communities to support, participate in, and develop creative Regeneration methods that promote the integration of local socio-cultural features, along with the competitiveness and attractiveness of cities, in the international panorama (Pratt, 2010). The purpose of this research is to dissertate the importance of Public Spaces for the success of urban regeneration trends that integrate cultural features, and simultaneously, contribute for the promotion of local identiy and creative public engagement. Considering the scarcity of open space per citizen in Tokyo, in comparison to other cities, Tokyo VOID is a research project (Rahmann, H. - The University of Melbourne; Jonas, M. - RMIT University) that focuses the importance of promoting flexible public uses in temporary vacant spaces, towards the reinforcement of sustainable principles in the city’s open spaces network (Rahmann and Jonas, 2010).
