The Current Situation of Retirement Income Provisions in Japan: Social Security Pension Schemes and Corporate Pension Plans

Japan has been faced with rapid population ageing for decades. This has continuously reduced the level of social security pension benefits. Based on this it is often said that corporate pension plans should play a wider role forward in providing retirement benefits. However, we also have to know that there is a limit to what corporate pension plans can do in place of the social security pension schemes. In this paper we extract lessons from the history of social security pension schemes in our country and try to define the roles of corporate pension plans and social security pension schemes. In conclusion we should keep adequacy of social security pension benefits even if the contribution rate becomes a bit higher. Corporate pension plans just enrich people's life in retirement. We have to remember that corporate pension plans were not certain means for reducing the poverty in old age and that for this reason social security pension schemes by social insurance were invented.
