In order to create safe public parks that are accessible to everyone, the role of neighborhood residents is important. The aim of this study is to identify the factors that affect the intention of the residents to deal with various problems in public parks, especially in terms of the types and extent of social networks among neighborhood residents, based on a survey conducted in Suma Ward, Kobe City. 837 respondents of the survey were analyzed using structural equation modeling. Three latent variables were set in the model -the trust among neighborhood residents, the size of personal networks in neighborhoods, and the participation in neighborhood activities. Results are as follows. 1)In order to form the intention to act for the problems in public parks, the trust is important. 2)The size of personal networks and the participation in neighborhood activities can stimulate the creation of the trust. 3)The role of the trust is important for large parks while the extent of social networks is important for small parks.
