Structure of Public Pension System

As a result of the enactment of the law for consolidation of employee pension systems on October 1 2015, Employees' Pension Insurance that has been applied to employees of private companies is now also applied to private school personnel and civil servants, etc.

Structure before consolidation of employee pension systems

The Basic Pension System (National Pension) is an universal system for all residents of Japan to which self-employed, salaried employees of private companies, civil servants, and private school personnel as well as dependent spouses of these workers participate.

Therefore, participants in employee pension system (Mutual Aid Pension and Employees' Pension) also participate in the Basic Pension System (National Pension), benefiting from these two systems at the same time.
