The Task Force Committee on Innovation of Medical Education for the 21st Century (the Ministry of Education) proposed two changes to the current medical education system, that graduate students are permitted to enter medical school whose term is four years, and that the clinical professor system would be introduced in the future. According to a survery on medical school systems, the majority of countries through the world (88.0%) provide for the 5-7 year term, and in such countries high school graduates are permitted to apply for the term directly. In contrast to it, there exists a graduate medical school system (four years) in quite few countries. Australia is making reformation shifting its system to the graduate medical school system because they valued it as the way of developping self learning competence. General Medical Council, G. M. C. in U. K. adopted the recommendation, “Tomorrow's Doctors”, and has motivated each medical school to reform its curriculum. The Dundee case is mentioned as a good one. Lastly the author compares the administration organization system for medical education of U. K. and U. S. A. with the one of Japan.
