Abstract
The contemporary art festival inspired the residents to work voluntarily through the project Mori Radio Station x Shinyukai, (1) Wide generalized trust was built among artists, residents, volunteers, and public officials through working together. (2) A loose code was created under the motto ‘energetic, no pressure, fun’. (3) A network was formed by briging together diverse people and organizations; (4) The establishment of trust and networks promoted voluntary cooperation; and (5) A ten-year consistency was secured. As a result, there is room to assume that bridging social capital was formed from the point of view of the community generated by the art activities. On the other hand, in terms of community activities, it cannot be said that that the same has been formed, as it did not extend over the whole district.
