However, the medical profession claimed that its professional freedom of practice was being hindered and resisted government control. After World War II, the American mission in charge of reforming social security strongly advised that Japan should have a network of public hospitals and abolish private practice. The Ministry of Health and Welfare followed this advice and made a plan to construct the proposed network throughout the country, but implementation faced financial difficulties. Then Japanese economy took off after the Korean War and along with success in establishing a universal health insurance scheme came again the call to swing back to the private sector. In 1962, the upper limit for inpatient capacity was set to the number of beds in public hospitals, although the limit was not applicable to private hospitals. After that private facilities continued to construct beds and many clinics grew to become hospitals—most of them small, private institutions (Gunji 1994).
