The present study examined how media discourse on biotechnology using genetic engineering has changed in Japan. Specifically, using the online database of the Asahi newspaper, the annual numbers of articles concerning biotechnology were counted, and an analysis of the content was conducted. The results show three major findings: (i) the number of articles has gradually decreased since 2001, (ii) the frame of economic prospect has been considerably dominant since 2001, (iii) patterns of media discourse on "regulation," "food," and "concern" of biotechnology have dramatically changed, while patterns of media discourse on "medical issues," "generic research," and "economics" have remained stable. The discussion focuses on how biotechnology has been accepted as an accomplished fact under the frame of economic prospect by media discourse in Japan.
