The article delineates how actors invoke nationalizing accounts—accounts that turn local conditions, actions, and actors into national ones—in everyday talk. Taking the case of Japanese university scientists depicting their commercialization trajectories after the adoption of a set of policies that originated from the U.S., the article delineates how scientists stipulate what they do is Japanese. I outline the discursive practices through which they posit that the cause of others’ actions, or of they themselves, derives from some kind of ethno-national distinctiveness. (...) Interviews show how such nationalizing accounts were made through the inevitable gaps between local practices and formal global structures. Scientific and commercialization practices in Japan that deviated from the original form were explained not only through the institutional differences between the U.S. and Japan, but also through lay categories of “culture,” ethno-psychology, and readily available tropes about Japanese history. In such nationalizing accounts, what the Japanese scientists did under these new, and explicitly global policies, was argued to be fundamentally Japanese because they were rooted in and caused by the ethno-national character. As new institutional theory suggests, a decoupling between formal rules and local contingencies is a hallmark of any institution. The article further shows that such decoupling could then be used as a resource for everyday nationalism. At least in some cases, the global adoption and the localization of a global form may create an opportunity to enact the nation, contributing to a discourse that posits that an imagined community is distinct and special, precisely as the world becomes more globalized.
