An advisory panel to Prime Minister Yoshiro Mori wants rich elderly people to contribute to social security again to contain the rise in costs being paid by working people, the panel's final report says.

The panel of social security experts, led by Keimei Kaizuka, a professor at Chuo University, was tasked with revamping a social security system that will have to serve a rapidly aging population amid a declining birthrate. The report is expected to be submitted to Mori by the end of next week.

While an overall rise in social security costs is inevitable, the report says the burden assigned to the working population should be kept as light as possible while maintaining the current system of premium payments.
