Abstract
In the provinces of Suoh and Nagato of the Mohri clan during the Edo period, medical education was individually developed in the principal clan at Hagi and 4 branch clans. Acceptance of the western medicine in this province was stimulated probably due to the closer situation to Nagasaki and to the cross-road position of Shimonoseki. Historically, Igakukan at the Tokuyama clan and Kengakudo, a private school in the same district were the old medical schools. Koseido(Koseikan)that was founded in the principal clan at Hagi during the Tempo era was the first full-scale medical school covering both the oriental medicine and the western medicine. Entering into the Meiji era, medical schools at Akamagaseki and Mitajiri started, but they were short-lived. The real modern medical education did not start until the Yamaguchi Prefectural Medical School was founded in 1944 in this district.
