The starting point for the considerations in the article is the statement of Keiko Yamanaka that the Japanese know nothing about resistance to the bacterium represented by another human being. In the article, however, we put forward the thesis that Japanese culture has developed a collective immune system resulting not from individual but from shared systemic immunology in connection with the performance of family, professional and social functions. The analysis of Japanese ‘cultural immunology’ includes an examination of the ways (...) of functioning of the body in contemporary Japanese culture. To this end, we first discuss the relationship between humans and nature in Japanese religious-ethical tradition. Next, we examine the Japanese relationship to the body as a special part of nature. Then we analyze the tension in the Japanese culture between individual and sociocultural bodies. In conclusion, we show what the sociocultural body is and how it functions in the system of ‘cultural immunology’ in contemporary Japan. (shrink)
