Abstract
Continuous update of city has become an important issue. We focus on intermediary organizations to promote the district renovation. In this paper, we consider the case of Matsumoto-cho, where an intermediary organization and neighborhood association have worked together, consequently to renovate 8 out of 15 vacant facilities into dwelling and shopping ones. We concluded that the technologies required to such an support organization were share of interest, district plan, operation of working groups, entrepreneurship support of community business, funding, visioning support, coordination of events, networking of external resources, and matching vacant house.
