Not since just after World War II has there been as dramatic a change in the system of medical education in Japan as in the last several years. Medical school curricula are including more education that mimics clinical practice through problem-based learning, organ-based curricula and implementation of the objective structured clinical examination (OSCE). In response to criticism and concerns, the Japanese government has also implemented 2 major changes in the system of postgraduate medical education. First, a 2-year structured internship has been required of all medical school graduates; the first cohort to undertake this completed it in April 2006. Second, an internship matching system was adopted and first implemented in 2003.
