Comparative scholarship on health systems has largely relied on institutional approaches, based mainly on the public–private divide. This article argues that political dynamics are central to understanding the shaping and evolution of health systems. France offers a particularly instructive case due to the complexity of its system: intertwined public-private mix, changing modes of governance, persistence of historically rooted arrangements and institutional disjunctures. Drawing on policy tracing, with attention to critical realism, and conducting a contextual and historical analysis, the article shows how actor configurations, power resources, ideological conflicts and political crises have structured the French health system over time. The introduction presents the characteristics and paradoxes of the French system, which this article contributes to explain. The following two sections trace the separate institutionalisation of the two key policy actors: first, the nineteenth-century formation of the medical profession, structured as a national scientific elite, local political notability, and a corporatist organisation ; second, the belated and contingent construction of a national health insurance system, confronted with the resistance of organised medical liberalism. The third section analyses how the power relationship between the medical profession and the government have evolved after a major change of the political regime (Vth Republic) and pressure from economic and social challenges, such as modernizing hospital infrastructure, universalising access and containing expenditure. It shows growing government leadership, and yet limited statecraft over parts of health sector. The conclusion points to the interest of long-term policy tracing, as a method that allows to uncover underlying power structures and identify the causal factors of change, an approach applicable to other national cases.

Background
Japan’s postwar welfare state developed around the universal Statutory Health Insurance System (SHIS), a complex public–private arrangement involving diverse insurers, providers, and government actors. Because most healthcare providers operate outside direct government control, the regulation of healthcare organizations and the setting of SHIS payment rates have remained central concerns in Japanese healthcare politics. However, the diversity of institutional arrangements and policymaking processes across different healthcare policy arenas has received limited systematic attention.
Methods
This paper conducts an institutional analysis of policy documents, media reports, and scholarly literature to examine Japanese healthcare politics over the past three decades.
Results
The paper begins by outlining the institutional structure of the SHIS and the key actors involved. It then examines four major arenas of healthcare policymaking: consensus-building in national councils, biennial revisions of medical fees and drug prices, system-wide health insurance reforms, and healthcare delivery reforms involving complex central–local relations. The analysis further considers how these arenas are affected by recent political transformations. These transformations include stronger political leadership, shifts in party competition, and intensifying conflicts over cost containment and cost-sharing. The analysis also highlights the emerging but uneven influence of patient voices and public opinion; while these forces remain structurally limited overall, they can occasionally prove decisive.
Conclusion
Rather than constituting a single unified process, contemporary healthcare politics in Japan is best understood as a differentiated system in which multiple policy processes coexist across distinct arenas. At the same time, changing political structures are reshaping distributive conflicts—increasingly centered on patient cost-sharing—within a healthcare system historically committed to universal coverage.
