This paper examines the cause and consequences of affective polarization in Osaka through an analysis of two sample surveys of residents in Osaka City. Recent studies suggest that affective polarization has resulted in a “Crisis of Democracy” by intensifying conflicts among groups or individuals, making compromise more difficult. Accordingly, this paper analyzed the current situation, causes, and consequences of affective polarization in Osaka City, where political parties are fiercely opposed to each other, obtaining both expected and unexpected findings. First, the level of affective polarization in Osaka was not critical, though not so low as to warrant optimism. Second, Online media has no significant causal effect on affective polarization. In other words, factors other than media exposure cause affective polarization in Osaka. Third, high levels of affective polarization cause serious distrust of politicians and decrease generalized trust among citizens.
