Abstract:

In 1945–46, representatives of the U.S. government made similar discoveries in both Germany and Japan, unearthing evidence of unethical experiments on human beings that could be viewed as war crimes. The outcomes in the two defeated nations, however, were strikingly different. In Germany, the United States, influenced by the Canadian physician John Thompson, played a key role in bringing Nazi physicians to trial and publicizing their misdeeds. In Japan, the United States played an equally key role in concealing information about the biological warfare experiments and in securing immunity from prosecution for the perpetrators. The greater force of appeals to national security and wartime exigency help to explain these different outcomes.

His fervor, and the nationalist indoctrination of his schooling, quickly subordinated any sense of conscience. By his second month at Luan’s army hospital, Yuasa was aggressively performing vivisections on live Chinese prisoners, and diverting dysentery and typhoid bacillus to Japanese troops for use in biological warfare.

“I was in denial of the things I did in Luan until the war was over. It was because I had no sense of remorse while I was doing it,” Yuasa, 90, told The Japan Times in a recent interview.

“We believed that the orders from the top were absolute. We performed the vivisections as ordered. We erased any sense of culpability by doing so, even though what we did was horrendous.” [Full text]
