Japan’s Public Universal Health Insurance System Reform: Lessons for Achieving and Maintaining Universal Health Care Coverage

The global health community has been aiming at ensuring health coverage for all. To achieve universal health care coverage, the German Social Health Insurance model is one solution. However, one major disadvantage of Social Health Insurance is the fragmented insurance plans, exemplified by 3,500 insurance plans in Japan’s public universal health insurance system. To improve the financial sustainability of Japan’s public universal health insurance, policy options include consolidating fragmented plans as already implemented in Germany and South Korea.

This presentation has two major goals. One is to evaluate the optimal health insurance size in consolidating 3,500 insurance plans in Japan through a simulation analysis using the best available micro data in Japan. The other goal is to discuss the global policy implications based on the experiences of Japan's public universal health insurance.
