Japan passed the Certified Care Worker Act in 1987 and initiated specialized nursing care education and a dual-track approach to national qualification to cultivate care professionals. This study adopted a traditional literature review methodology to investigate the historical evolution of Japan’s legal regime for care workers. It searched for official historical Japanese policy documents (1970–1990) in domestic and foreign databases, including IPSS, CiNii, and NDL. This study identified four major elements contributing to Japan’s success in enacting regulations governing care workers, namely (1) strong central government leadership, (2) the adoption of a dual system for certifying social workers and care workers, (3) a collaborative training system involving both employers and employees, (4) and support from the care industry.
