This paper gives an account of the development of Japan's concrete dam construction technology in the 1950's and 1960's by analyzing the project documentary films, which record both the technical and human aspects of the projects. As the results of examining 25 project documentary films on the major dams including Maruyama, Kamishiiba, Sakuma, Ikawa, Arimine, Okutadami and Kurobe dams, it is suggested how the mechanized construction method and the concrete cooling method, required for the dams over 100 meters high, were established. The details are as follows: (1) Both machinery operations at the project sites and the final works after the mechanized materials transportation were supported by highly skilled workers. (2) Pumps, vibrators and steel forms made in Japan were rapidly improved by trial and error, and they were systematized to achieve an effective dam construction method. (3) The concrete cooling method was established after some researches.
