Using critical discourse analysis, this article analyzes the discursive representation of the Fukushima nuclear disaster in The Daily Yomiuri, part of the largest and most influential media conglomerate in Japan. A critical discourse analysis of The Daily Yomiuri reveals that Japanese national identity and the ideology of technoscience are reproduced through two discursive constructions: a diminished ‘risk’ from Fukushima radiation and citizens’ national duty in the nuclear crisis. Within these two constructions, 11 major techniques are identified by which The Yomiuri discursively mitigates the risks from Fukushima and calls Japanese national identity into the service of the nuclear industry. The article concludes with implications for understanding the impact of political discourse in mass media on other policy debates in Japan and elsewhere.
