We, as final year medical students at University of Tsukuba, had an opportunity to take some clinical clerkship courses at McMaster University for three months, from April 3 to June 23, 1989. The curriculum was unique and different from the one we have in Japan, especially in regard to its clerkship. We found it very instructive and stimulating to work with McMaster students and staff members at the hospitals. We learned a lot from this wonderful experience and we want to thank everybody who gave us a warm support.
