The main concerns of this project are the perspective of social innovation (i.e., social transformation through new ideas) and the methodology of community solutions (i.e., problem solving by the community). We focus on approaches that cut across society, the economy, culture, and technology, where cultural contexts exist behind economic systems, where spontaneously formed consumer communities are critical success factors for corporate activities, and where elements traditionally considered "weak" are in fact the key to problem solving. We will focus on approaches that cut across social, economic, cultural, and technological boundaries. We will conduct empirical research, theory building, policy proposals, system design and tool development, and fieldwork on game theory, social capital theory, traditional organizational theory such as "yui, kouza, and za," community evaluation methods, social marketing, sports business, innovation through policy, etc. Fieldwork will be conducted.
