[Japan Focus Introduction: The world has little noted nor long remembered the multinational character of atomic bomb victims including Americans of Japanese ancestry, Chinese, and, by far the largest group, Koreans. Many of the tens of thousands of Korean hibakusha were forced laborers conscripted during the war to work in mines and factories of Japan's leading corporations. Like their brothers conscripted into the Japanese military, and their sisters kidnapped into sexual slavery, Korean forced laborers were cut loose following the end of the war, frequently denied the most rudimentary benefits, shortly deprived of Japanese citizenship and, notably in the case of those who returned to Korea, denied access to government-funded treatment available to hibakusha in Japan. The landmark Supreme Court case described here for the first time held the Japanese government liable for compensation to the Korean atomic victims, At the same time, while severely criticizing the wrongdoing of the Japanese government, it denied government or corporate liability to provide compensation for crimes associated with slave labor on grounds of the statute of limitations and treaty provisions. The present article, and the literature generally, while shedding much light on Japanese war responsibility, make no mention of another unmet responsibility: is it not high time that the United States contribute financial support for the treatment of the surviving hibakusha, whether in Japan, Korea, Taiwan or the United States?]
