As a member of two parallel projects sponsored by the Japanese Society for the Promotion of Science (JSPS), a considerable part of my work has been revolving around the methodological issues of comparison and recursivity. Comparison has been a central tool of anthropological research, but it has lost a lot of its appeal since the 1980s. At the same time, comparing people, things, medications or cultures has rapidly become a part of everyday life, not at least due to technological and scientific innovation. We have organized a session at the 4S Meeting in Tokyo in 2010, and two international symposiums (Traveling Comparisons 2009, Translational Movements 2012) to tackle with such important trafficking between anthropological methods and technosocial realities. The results of these explorations have been published in two special issues of the same titles in the journals of East Asian Science, Technology and Society (see here) and NatureCulture (see here), respectively.
