Abstract
A central question of this chapter is how we can relate the unique ethos of Japan to the ways that influences of international bioethics, civil rights and legal reforms have shifted medical research in Japan from the legacy of the structured paternalism and impunity that allowed abuses to be committed by medical researchers in the World War II era, including in Unit 731 and in medical schools in Japan, to contemporary research agendas and policies. Throughout the twentieth century, Japan has been a centre of research and innovation. The pro-technology attitudes still exist in current Japan, with the evolution of bioethics. Although we can trace the origins of bioethics in Japan back through millennia, with the Ainu indigenous practices and relationships to nature, the sophisticated hierarchical relationships expressed in the seventh century A.D. book the Kojiki, the conversion of forest to rice paddies, emergence of an integrated religious system including Shintoism and Buddhism, and the sophisticated class system supported by linguistics and social relationships, this chapter would argue that one of the most influential influence for this question is the Samurai tradition. This tradition values both autonomy and informed choice, while also allowing the legacy of tolerance of the elite classes to make decisions that may sacrifice some persons for the greater good. While principles of solidarity and social justice are a solid basis for universal health insurance they also allow sacrifices when necessary. Informed consent is now widely accepted, and bioethics is part of a transition which is transforming Japanese society from a paternalistic society to an individualistic one. Among the issues that will be used to illustrate the situation, are the functioning of research ethics committees, large gene bank and epidemiological projects, organ transplantation, truth telling, euthanasia and the public health measures such as mask wearing in the current COIVD-19 pandemic.
