ABSTRACT
Each medical specialist certification system in internal medicine and its subspecialities was founded and controled byeach medical society, but not by the public. Thus, each system had not been harmonized each other, and not recognizedas the public system until the the Ministry of Health, Labour and Welfare (MHLW)'s declaration of permission for publicnotification of each certificated medical speciality when approved according to their criterion. Based on the longstandingdiscussion and negotiation in the special committee on internal medicine of the Japanese Board of MedicalSpecialist, on the other hand, the Japanese Society of Internal Medicine (JSIM) and the societies of subspecialities in theinternal medical fields agreed to build up the so-called 2 stair-system as the framework of medical specialist certificationsystem, where the Certified Member of the JSIM is inevitable for application or renewal of the Fellow of the JSIM andother certifications of medical specialist of the internal medical subspecialities. In face to the new compulsory postgraduateclinical training system with super-rotation for 2 years starting from 2004 fisical year, JSIM decided that 2 yearpostgraduate clinical training is included to the 3 year training period necessary for the application of the Board CertifiedMember of JSIM, because clinical training with super-rotaion system aimed to master the capability of primary medicalcare is recognized to be also an essential part of the training program for internists. For the better medical specialist certificationsystem in the future, the Japanese Board of Medical Specialist should be approved to be the public and independentorganization for quality control of Japanese medical specialist certification system as a whole to improve medicaland welfare quality which fit for the requirement of Japanese people in the 21th century.
