This paper aims to analyse a structure of relation among social media use, community participation and social capital. The author conducts quantitative empirical analysis based on Japanese two cities in year 2011 and 2012. The results suggest that social media use might affect community participatin by means of two paths. The first is indirect path that goes through online bridging social capital and then general trust. The second is direct path that goes beyond social capital factors or general trust.
