Resumen
This paper examines how social media are affecting Japanese civil society organizations, in relation to efficacy and political participation. Using data from the 2017 Japan Interest Group Study survey, we analyzed how the flow of information leads to the political participation of civil society organizations. The total number of respondents (organizations) were 1285 (942 organizations in Tokyo and 343 from Ibaraki). In the analysis of our survey we focused on the data portion related to information behavior and efficacy and investigated the meta-cognition of efficacy in lobbying among civil society organizations in Tokyo and Ibaraki. We found that organizations that use social media were relatively few. However, among the few organizations that use social media, we found that these organizations have a much higher meta-cognition of political efficacy in comparison to those that do not use social media. For instance, social media usage had a higher tendency of having cognition of being able to exert influence upon others. We also found that organizations that interact with citizens have a higher tendency to use social media. The correspondence analysis results point towards a hypothesis of how efficacy and participation are mutually higher among the organizations that use social media in Japan.
