Abstract
Over the past decade, genetically modified organisms have come to be viewed as problematic in Japan, as evidenced by a large number of newspaper articles covering questions ranging from the unknown ecological impact of GMOs to uncertainty about food safety, and by the fact that a number of consumers’ groups have organized activities including demonstrations at the experiment stations and the submission of petitions to the government. Against this backdrop, this article attempts to understand the changing interpretation of the perceived rational social order in the context of the Japanese GMO controversies. Drawing on the French Theory of Conventions, the article will shed light on the conventions that serve as templates enabling actors to interpret what it means to introduce GMOs and what constitutes a rational decision concerning GMOs. The article will argue that rationality is best viewed as an emergent and interpretive process involving interpretation and negotiation by and among actors, and that conventions which may be taken for granted are nevertheless unstable and mutable.
