I am an Associate Professor of Contemporary Political Analysis at the Graduate School of Law and Political Science, Tohoku University, one of Japan's leading national universities, and a Visiting Researcher at the SmartNews Media Research Institute. I received my PhD (with the Dean's Award for Outstanding Doctoral Research) from the University of Tokyo in 2021.
My research sits at the intersection of political communication and Japanese politics, with two main lines of inquiry. The first concerns the role of news media in democratic politics — particularly the declining influence of regional newspapers, news deserts, media bias, and the changing landscape of news consumption. I draw on original large-scale datasets of Japanese regional and national newspapers, combining quantitative text analysis with electoral behavior research. The second examines voting behavior and voter attitudes, including issue voting and the design and effects of Voting Advice Applications (VAAs). I have been involved in large-scale original surveys of both voters and politicians, including the University of Tokyo–Asahi Shimbun Joint Survey (UTAS).
My monograph Newspapers and Politics in Contemporary Japan: Regional and National Papers, Voters, and Politicians (University of Tokyo Press, 2023) provides a comprehensive empirical analysis of how newspapers shape voters and politicians in Japan. It received the 10th Uchikawa Yoshimi Memorial Media Studies Award (2025), the Japan Public Policy Studies Association Encouragement Award (2024), and the Japan Electoral Studies Association Outstanding Paper Award (2022), and was reviewed in Social Science Japan Journal.
My peer-reviewed work has appeared in the International Journal of Press/Politics, Social Science Japan Journal, Politics & Gender, and the Journal of Elections, Public Opinion and Parties, among others. I have a paper conditionally accepted at Political Psychology, and I am a contributor to Japan Decides 2026 (Palgrave Macmillan), writing a chapter on mass media coverage of the 2026 Japanese general election. I am also scheduled to present at the APSA Annual Meeting in September 2026.
I am planning an overseas research visit from autumn 2027 through summer 2029 and am actively exploring host institutions.
