Japan's high-quality healthcare system despite physician shortages: Exploring the paradox and pathways toward sustainable healthcare

Uenishi M, Song PP, Karako T

Japan's rapidly aging population presents significant demographic pressures, and yet the country maintains high standards of healthcare delivery with remarkably low rates of preventable and treatable mortality. According to the latest data from the Organisation for Economic Co-operation and Development (OECD), Japan ranks 35th among 38 countries in physician density (2.6 per 1,000 population), and yet it records 12.1 physician consultations per person per year―among the highest in the OECD. This article analyzes this paradoxical situation―where high medical performance is maintained despite relatively few physicians―by examining both institutional strengths and emerging vulnerabilities. The strengths include universal health insurance with high public funding; a resource-intensive medical infrastructure; and a robust support network of allied healthcare professionals. Simultaneously, we identify the following vulnerabilities: increasing demand intensity; shortages and an uneven distribution of physicians; hospital financial losses; the limitations of effective gatekeeping under free access systems; and the amplified workload resulting from the concentration of authority and responsibility among physicians. Moreover, we examine initiatives needed to ensure the sustainability of insurance-based healthcare, including: redesigning supply-demand planning and education policies; expanding task sharing and securing funding sources; designing incentives for essential and regional healthcare services; and restructuring access models to value-based utilization and need-based care.
