  • Changing regional university availability and inequality of educational opportunity in Japan

    Open Access•Ryota Mugiyama, Kohei Toyonaga•ARTICLE•European Sociological Review•2026•References: 55

    The uneven distribution of universities across regions has been argued to create educational inequalities based on place of residence. While studies have shown positive associations between college proximity, measured by distance to nearest college or its presence, and enrolment among local residents, regional availability has often been measured insufficiently, and longitudinal evidence on the relationship is limited. Using multiple social surve…

    Open Access•Kohei Toyonaga•ARTICLE•Research in Social Stratification…•2025•References: 11

    Although noncognitive skills and personality traits are widely recognized as crucial for understanding social inequality, their effects on labor market outcomes remain underexplored. This study investigates how employers evaluate personality traits of job seekers, focusing on Japan, where the widespread adoption of the Synthetic Personality Inventory (SPI)—a screening tool that combines cognitive ability and personality assessments—has made these…

  • Role of Cohort Size in Trends in Class and Occupational Returns to Education at First Job

    Ryota Mugiyama, Kohei Toyonaga•ARTICLE•European Sociological Review•2022•Cited by: 2•References: 50

    Downward trends in class and occupational returns to education have mainly been attributed to educational expansion via credential inflation. However, despite this rapid educational expansion, trends in returns to education vary across societies. This study proposes that changes in population size can contribute to offsetting the impact of educational expansion, controlling for demand-side factors. Using nationally representative survey data from…

  • Educational Expansion and Inequality of Access to University

    Open Access•Kohei Toyonaga•ARTICLE•The Annual review of sociology•2020

    This paper examines whether the effects of social class and academic achievement on access to university have changed due to rapid educational expansion since the 1990s. Analyzing the National Survey of Social Stratification and Mobility in Japan, the magnitude of the effects of the father’s occupation decreased significantly after educational expansion only in male samples, but impacts of the father’s and mother’s education have not changed sign…
