The object of this article is to clarify the factors behind the development of Japanese process computers in the 1960s. The study concentrates on the relationships between the process computer manufacturer Toshiba, Hitachi and Mitsubishi Electric and thermal power plants. During the so-called high-economic growth period, a remarkable expansion of demand for electric power in Japan required increased capacity of thermal power plants. As a result, plant facilities became more complicated, and a larger number of computers were needed for controlling them. Process computers at these plants had to perform such functions as data logging, sequence monitoring, and partial and full-scale automation in order to operate the power plants safely and efficiently. Process computer manufacturers coped with the demands of the thermal power plants by cooperating with internal heavy electric divisions, entering into tie-ups and alliances with foreign computer manufactures, and engaging in joint research and development with electric power companies. In conclusion, Japanese computer manufactures were able to compete with imports in process computers by responding to the demands of the electric power companies, not by benefiting from an industrial policy limiting imports to protect Japanese manufactures.
