title: Conflicts between Public Car Insurance and Public Medical Insurance in Japan: International Comparison Survey.
abstract: This paper clarifies essential issues regarding conflicts between public car insurance and public medical insurance in Japan, presenting the findings of an international survey to detect similar problems in other countries and discussing possible options for the resolution of these problems. Three essential issues are important to note: (i) Different prices between the two systems of public insurance provide stakeholders with the irrelevant incentive to apply public medical insurance in the case of car accidents; (ii) Public medical insurance sometimes covers medical expenses due to car accidents, although it should not cover them in principle; and (iii) The costs are imposed on tax payers unconsciously when people use public medical insurance for car accidents. Five findings were obtained from the international survey: (1) Most countries have compulsory car insurance; (2) Private insurance companies manage the financial affairs of compulsory car insurance in most developed countries; (3) Fault for casualties is not considered in the compensation of medical expenses in most countries; (4) Japan is unique in that people can choose between the two systems of public insurance; and (5) Prices for the same medical services differ between the two systems of public insurance in only a few countries. In consideration of the above findings, we provide five options for the resolution of this issue from the viewpoint of victim relief.
