ABSTRACT
On December 8th of 1941, the year Dr. Yuasa Ken joined the army, the Japanese military attacked Pearl Harbor, signaling the beginning of the wider Pacific War. The staff of the Luan Hospital consisted of the director of the hospital, who was a Lieutenant Colonel, and eight army surgeons. Yuasa published an account of the war crimes he committed in China in Kesenai Kioku, as told to Yoshikai Natsuko. However, germ warfare was the least of the crimes committed by the medical profession. On the Chinese mainland, military doctors performed vivisection and medics used Chinese people for surgery practice. Those men used the methods of freezing and drying blood learned from wartime experiments on human subjects to turn blood they bought cheaply in slum areas such as San'ya, Kamagasaki, and Kotobuki-cho into dried-blood products that they sold to the United States Army at an enormous profit.
