I am a professor at Tokyo-based Tsuda UniversityI am a political scientist, and interested in comparative politics, computational social science, Japanese politics, and American politics.


I focus on American democracy and affective/ideological polarization: this theme is related to polarization and democratic backsliding. Also, I work on the rise of populism and its political impact. Theoretically and empirically, I have studied the impact of the rise of populism on democratic politics in the U.S., Japan, and other countries. Finally, I have worked on the impact of misinformation/disinformation (e.g., conspiracy theories) on democratic politics, such as Japan and the U.S.

As described above, I have been studying interrelated themes in various countries and periods, theoretically and empirically, using various methods.


My research has been published as three books on American political history from Japanese publishers and also published in journals such as Party Politics, Diplomatic History, Health Communication, PS: Political Science & Politics, Frontiers in Physics, and others. Also, I delivered academic presentations at OAH, APSA, MPSA, Policy History Conference, SHAFR, SPSA, and so on.

I earned an S.J.D. from Keio University in 2007. Before joining Tsuda University, I was a Fulbright Scholar at Temple University in Philadelphia and a research fellow at the Japan Institute of International Affairs, which is a private and non-partisan think tank focused on foreign and security issues.

I was born in Hyogo, Japan. And I spent part of my childhood in London, United Kingdom (1985 to 1989), where I attended Woodridge Primary School in North Finchley.
