During World War II, Japanese Unit 731 conducted a large number of germ warfare and human experimental research in China. After the war, the Tokyo Trial under the leadership of the United States did not conduct a trial for such medical atrocities. Instead, it reached a secret deal on the condition that Japan was exempt from war crimes and the United States obtained research materials, so as to accumulate for American biological weapons research after the war［1］。 The United States maintained these materials as classified archives, and it was not until the 1980s, when these archives were discovered and declassified in the United States, that the academic community began to gradually pay attention to and discuss this medical atrocity. Eubios Ethics Institute (Eubios) is a non-profit organization founded in Christchurch, New Zealand and Tsukuba, Japan in 1990. It is the earliest bioethics research center in Asia.Eubios Journal of Asian and International Bioethics(Asian and International Journal of Bioethics) is the organization's publication series that publishes research results on related issues, including research articles on medical atrocities in Japanese Army Unit 731. The problem of medical atrocities in Unit 731 involves the historical and realistic problems of China and Japan. Therefore, this paper takes the research articles of Chinese and Japanese scholars on medical atrocities and scientific research ethics as examples to explain the similarities and differences between Chinese and Japanese scholars and the changes of research trends on this issue, and tries to explore the methods and paths of this research.
