Abstract
This study aims to clarify the role of collaboration and processes of change in the consciousness of city government bureaus of housing, social welfare corporations, community comprehensive care centers, and community associations. These organizations are concerned with community activities in public housing estates. From 2013 to 2014, interviews with each organization were conducted two to three times. Consequently, the following results were revealed: 1. Community activities were conducted every month for three years from the start. The city government managed these activities and social welfare corporations, community comprehensive care centers, and resident’s associations played a role in managing these activities. 2. Community activities caused changes in existing activities and developed new activities. 3. The three-year activity led to independently-minded consciousness of community association.
