Japan's Financing Systems for Health Care of the Elderly

The multiplicity of Japan's health insurance system fails to achieve equality among the different insurance groups of the sharing of the financial burden. This "horizontal" inequality is effectively offset by a unique redistribution mechanism established in 1982. However, there is no reserve fund so that savings can be accumulated for the greater financial need in the future. This will inevitably lead to a heavier financial burden for the future working generation or more utilization of the personal assets of the elderly. How to achieve "vertical" or intergenerational equality in financing the cost of health care for the elderly is the biggest social policy challenge for Japan.
