[The association between the medical arts of Japan, Korea, and Ming Dynasty China during Toyotomi Hideyoshi's War].

Traditional Korean medicine's pronounced impact on Japan came about as a result of Toyotomi Hideyoshi's war on Korea in the late 16th century. The influences of Korean medicine on Japan were caused by the introduction not only of a large number of medical books printed in the Yi dynasty and the techniques of publication but also those of the people of talent. We researched one doctor who came to Japan during the war of the Bunroku periods. The name of the doctor was Kintokuho. He learned medicine from a Chinese, Unkai(YunHai). He caused the iatrogenic diseases in the first year and so he changed his medical prescription to fit Japanese. After this, his treatment produced a curative effect. After his death, his art of medicine was passed on to his pupils.
