In Japan the Mentally Disordered Persons Supervision and Protection Law (1901) and the Mental Hospital Law (1919) used to be the main laws for mentally disordered people. Subsequently, the Mental Hygiene Law came into force in 1950 but was criticised as it had restrained admitted patients and the provisions for procedures for the release of patients were inadequate. The purpose of the old law was to give medical treatment and custody to mentally disordered persons and to maintain and improve the mental health of the nation. In the revised law, enacted in July 1988, acceleration of social rehabilitation of mentally disordered persons and promotion of their well-being were added.
