Paper long abstract

This paper examines why Japan’s healthcare system has remained relatively insulated from financialization, despite the gradual introduction of market mechanisms. In this paper, financialization refers to a process in which healthcare institutions and medical practices are increasingly reorganized as investment assets, revenue-maximizing entities, or vehicles for financial returns, rather than primarily as professional or social services. While many advanced economies have experienced such trends through private equity ownership, hospital chains, and financial engineering, Japan presents a notable contrast.

Existing scholarship on Japanese healthcare has emphasized the role of the single-payer system, fee schedule regulation, and cost control in limiting healthcare expenditures. However, these explanations alone do not fully account for why hospitals and medical practices in Japan have not been widely transformed into financial assets. Building on the author’s previous research on the relationship between health insurance policy and medical professional organizations, this paper focuses on the role of the Japan Medical Association (JMA) as a mediating actor between market forces and healthcare provision.

The JMA has historically sought to protect physicians’ professional autonomy and clinical discretion, particularly within a system dominated by small, privately owned clinics and hospitals. While the association has not opposed market activity per se, it has consistently resisted forms of organizational restructuring that would subordinate medical practice to financial imperatives. This stance has had the unintended effect of limiting external capital penetration and constraining the financialization of healthcare delivery.

By highlighting the interaction between institutional design and professional organizations, this paper argues that marketization does not automatically lead to financialization. Japan’s experience suggests that professional politics can play a significant role in shaping how economic logics are translated into healthcare systems, offering a useful comparative perspective for scholars of political economy, business, and Japanese studies.
