This review article provides an overview of the scholarship on the establishment and reform of East Asian welfare capitalism. The developmental welfare state theory and the related productivist welfare regime approach have dominated the study of welfare states in the region. This essay, however, shows that a growing body of research challenges the dominant literature. We identify two key driving factors of welfare reform in East Asia, namely democratization and post-industrialization; and discuss how these two drivers have undermined the political and functional underpinnings of the post-war equilibrium of the East Asian welfare/production regime. Its unfolding transformation and the new politics of social policy in the region challenge the notion of "East Asian exceptionalism", and we suggest that recent welfare reforms call for a better integration of the region into the literature of advanced political economies to allow for cross-fertilization between Eastern and Western literatures.Keywords: Democratization, Post-Industrialization, Welfare Capitalism, Developmentalism, Japan, South Korea, Taiwan.East Asian welfare states have experienced comprehensive reforms in the last two decades.Following the regional "pioneer" of Japan, the neighbouring South Korea and Taiwan have introduced unemployment protection schemes, and have universalized health-care provision and old-age security. Also observed has been increased state intervention in child and longterm care in the region, including Japan. Welfare state expansion in the three countries, with the rise of social citizenship, challenges perceived wisdom in the literature. According to de-3 velopmental welfare state theory, and the related productivist welfare regime approach, social policy (driven by technocrats) is strictly subordinated to the primary policy goal of economic development, and therefore social welfare provision is confined to "productive" parts of the population (in particular, regular workers in key industries). However, recent policy expansion benefited presumably "non-productive" parts of the population as well (such as the unemployed, women, children, and the elderly), whilst the deregulation of employment protection undermined the developmentalist "welfare-through-work" system. This article reviews the literature on the establishment and reform of East Asian welfare capitalism. In so doing, we focus on the research examining the political and socio-economic drivers of the unfolding transformation of East Asian welfare capitalism; with a focus on Japan, Korea, and Taiwan. We show how democratization (that is, the end of authoritarianism in Korea and Taiwan, and the end of one-party dominance in Japan) and post-industrialization (that is, both labour market and family changes, such as the rise in female employment and the decline of traditional families) have undermined the post-war equilibrium of the East Asian welfare/production regime. Democratization has allowed the rise of political parties and societal actors in social policy-maki...
