He was an assistant professor at Waseda University between 2010 and 2012, and an associate professor at Osaka City University between 2012 and 2016. His research interests are in comparative political economy in advanced industrialized countries, comparative welfare states, comparative social policy, and so forth.

His Ph.D. dissertation explored political determinants of cross-national variations of long-term care policy for frail elderly people at Department of Political and Social Sciences, European University Institute, Florence. His journal article based on his Ph.D. thesis is awarded with the Early Stage Career Researcher Prize of 2012 by Social Policy & Administration. The revised dissertation Political Institutions and Elderly Care Policy: Comparative Politics of Long-Term Care in Advanced Democracies was published as a book from Palgrave Macmillan in 2012.

His current research project explores the impacts of partisan politics on social protection programs against "new social risks," such as reconciliation between paid-work in labor market and unpaid-work in households, poverty among lone parents, and precarious employment among low-skilled workers. His articles have appeared in academic journals such as Party Politics, European Journal of Political Research, Social Policy & Administration, and other Japanese journals.

  • Do populists support populism? An examination through an online survey following the 2017 Tokyo Metropolitan Assembly election

    Hieda Takeshi, Zenkyo Masahiro, Nishikawa Masaru

    Party Politics  2019  [Refereed]

     View Summary

    Based on an ideational approach, a burgeoning body of literature directly measured the populist attitudes among supporters of populist parties. However, few empirical works have examined whether these attitudes among voters also explain their preferences for politicians whom a political-strategic approach regards as populists. In addition, no research verified the applicability of individual populist scales to non-Western countries. To overcome these shortcomings, this study assesses populist attitudes among Japanese citizens and explores whether a respondent with these attitudes tends to vote for populist politicians in Japan. We conducted an online survey after the 2017 Tokyo Metropolitan Assembly election. Survey results revealed that the supporters of the Tokyoites First Party – a typical populist party in a political-strategic sense – lack the quintessential elements of populism. Further, several subcomponents of populist attitudes led to support for the Japanese Communist Party – a radical leftist party.

     View Summary

    This essay analyzes the way to improve the linkage between a theoretical model and empirical analysis in political science. Based on Goertz (2005), first, I exemplify that classifying concepts into three levels and rigorously conceptualizing the relationship among basic and secondary-level concepts contribute to assessing the validity of her theoretical model. Second, I show that conceptual analysis also facilitates a case selection. According to the Possibility Principle, only cases where the outcome of interest is possible should be treated as negative ones; cases there the outcome is impossible should be considered uninformative and irrelevant. Probing set relations among explanatory and explained factors allow a researcher to distinguish negative cases from irrelevant cases. Third, through critically appraising my own research, I demonstrate that fuzzy-set analysis can heighten concept-measurement consistency. When inventing a theoretical model through natural language, a researcher tends to develop a complex model with categorical set relations. However, empirical data usually have continuous values in reality. Fuzzy-set analysis adapts continuous data to set relations and enables a researcher to analyze necessary/sufficient conditions among them.
