Same same but different? Comparing institutional performance in the long-term care systems of Japan and South Korea

Abstract

Responding to a rapidly aging population, Japan and South Korea introduced social insurance-based long-term care systems (LTCSs) in 2000 and 2008, respectively. Korea studied and took up key features of Japan's system while evolving along its own trajectory in line with its healthcare system. The aim of the present study is to unpack the broad category of ‘social insurance’ to explore how distinct system inputs and designs in Korea and Japan related to outcomes in performance measured in terms of coverage, quality of care, and sustainability. In doing so, the study serves as an important starting point for advancing a new stream of social policy research on the comparative performance of LTCSs. Our findings demonstrate that despite adopting a common system type, differences in implementation of the social insurance model (particularly in terms of financing and governance) contributed to divergent performance, with Japan outperforming Korea on most indicators during the observed period. This bears contrary implications for policymaking in the two countries: Whereas Japanese policymakers are faced with the challenge of promoting quality while containing spending, in Korea greater investment is required to strengthen the workforce and build up community care.
