Perceived Political Polarization and its Differential Impact on Political Participation: Evidence from Japan (2005–2019)

Abstract

Political polarization has been a growing concern in Japan, particularly in recent years with the upsurge of nationalism and populism. However, little research has examined how it relates to the political behavior of the Japanese people. Using data from the 2005–2019 Japanese Electoral Studies (JES), this study shows that political polarization manifests itself in different ways depending on the specific policy domains that citizens perceive as divergent. Specifically, I discover that people who perceive higher levels of policy divergence between left- and right-wing parties on domestic and international policies are more likely to vote and participate in politics through publicly accessible networks, while there appears to be no evidence showing that perceiving high levels of policy divergence on economic issues has a meaningful effect on any type of political participation. Implications of these findings as well as directions for future research are discussed.
