The Shaping of Japanese Discourse on Nuclear Energy Technology in the Early Post-War Period

This article explores Japanese perceptions of nuclear technology from 1945 to 1956, the early stage of the introduction of nuclear technology, by using discourses of the government and of antinuclear civil movements. It is based on the theoretical framework that discourses construct social perceptions of science and technology. For this purpose, statements such as official documents of the Japanese government and declarations made by the antinuclear movement were used as main resources of analysis. This article finds that various technological aspects influenced the formation of the Japanese nuclear technological system. In addition, the Japanese government tried to keep open the possibility of developing nuclear weapons. It tried to justify its ‘peaceful use of nuclear power’ by portraying itself as the sole victim of nuclear weapons while hiding its intention to develop nuclear weapons. Moreover, the nuclear safety myth was formed at the beginning of the introduction of nuclear technology. As a result, we can see that in Japan, the nuclear safety myth was growing from the beginning of the introduction of nuclear technology amid a dichotomous understanding of good and bad uses of nuclear power and the desire to enter an advanced state of science and technology.
