This re-employment system was established to facilitate coordination between the employment and pension systems so that national public employees will be able to devote themselves to duties without concerns about post-retirement life. It is also designed to assist them to effectively utilize their abilities and experience accumulated over a long period of time. In light of the purposes of the system, which was established in response to Japan's full-scale aging society and the raising of the age for the start of the public pension payments, appointing officers/authorities must note that they are required to re-employ as much as possible persons with the willingness and abilities to continue to work as a public service employee after mandatory retirement.
The "Policy on Promotion of the Re-employment of Elderly National Public Employees" (Decision of the Personnel Management and Administration Council dated June 27, 2001) also requires active efforts to re-employ elderly national public employees based on utilization of the re-employment system.
