Yusaku Horiuchi

Yusaku Horiuchi is Professor of Government and Mitsui Professor of Japanese Studies at Dartmouth College, jointly appointed in the Department of Government and the Program in Quantitative Social Science. His research spans comparative politics, political methodology, and international relations with regional expertise in Japan.

Education:

• B.A. from Keio University (Tokyo, Japan)
• M.A. from Yale University
• Ph.D. from Massachusetts Institute of Technology

Research Focus: Horiuchi specializes in experimental political methodology, particularly conjoint analysis and causal inference designs. His substantive work examines Japanese electoral politics, global public opinion dynamics, diversity attitudes, and the political economy of elections. He frequently employs survey experiments and natural experiments to study how institutional changes and information exposure shape political behavior.

Publication Trends: His recent articles (2021-2025) focus on global public opinion shifts, diplomatic influence, and methodological innovations in causal inference. Earlier foundational work established new techniques for detecting electoral fraud and measuring policy preferences. Geographic focus alternates between Japan-specific analyses and cross-national comparative studies.

Honors:

• Alan Rosenthal Prize for legislative studies scholarship
• Endowed Mitsui Professorship in Japanese Studies

Collaborations & Projects: Leads international research consortia including COVID-19 global attitude studies (69 countries) and directs the 'Workshops Without Borders' initiative for Japan scholars.
