Post-World War II, the vocational parent system was established in Japan in 1951--based on the Child Welfare Law--to provide aftercare for older dependent children. The vocational parents lived with the children and provided the guidance necessary for them to live independently. The evolution of the vocational parent system is divided into three periods for this study: the 1950s, the end of the 1950s to the mid-1960s, and the mid-1960s to the 1970s. Vocational parents were primarily from small- and medium-sized business establishments who could provide personal guidance. This prevented the children from becoming skilled workers and seeking employment in large companies. Vocational parents were expected to provide "parental love" to the children without compensation, despite having to bear the childcare costs and blunders at work. The more the government, welfare personnel, and newspapers sought the welfare ideal of parent-like assistance, the more detached they became from the realities of the working environment and the needs of the children. Consequently, the disparity may have contributed to the decline in aftercare in post-war Japan.
