Abstract Professor Miriam L. Kingsberg Visiting Scholar at Columbia University Assistant Professor of Modern Japanese History, University of Colorado at Boulder Fieldwork, Ethnology, and Empire: The Making of Japan’s “Transwar Generation” of Social Scientists Born in roughly the first two decades of the twentieth century, the “transwar generation” of Japanese social scientists was intellectually active before 1945, yet responsible for rebuilding theories, disciplines, and institutions afterwards. This paper looks at the formation of transwar social scientists as a generational cohort. Rather than ideology, what bound these scholars together was their shared commitment to methodology. Japanese social scientists of the 1930s and 1940s, like their counterparts worldwide, were captivated by Polish-born British social anthropologist Bronislaw Malinowski’s fieldwork involving long-term immersion among the population under analysis. During the “Malinowski boom,” Japanese students of the imperial Other embraced direct, sustained experience as the foundation of legitimate, “objective” scholarship. Rather than working alone, however, they generally ventured into the field in teams to minimize danger, maximize resources, and collect comprehensive information. Team fieldwork in turn produced a unique relationship among Japanese social scientists, their research subjects, and the imperial state. Whereas this methodology allowed social scientists to secure their professional position, it also suppressed most potential for political dissent, and cast a long shadow into the postwar period.
