Abstract: Yamazaki Toshio is a renowned historian of technology and industrial archaeologist in Japan. His contribution to the study of the history of Japanese technology is mainly reflected in the division of the development process of the history of Japanese technology, emphasizing that “technology belongs to the people”. He argues that technological development should align with the actual social needs and advocates breaking down the barriers between disciplines to promote exchanges between natural sciences and humanities and social sciences. At the same time, he has also defined the concept of industrial archaeology and clarified the relationship between industrial archaeology and the study of technological history, actively promoting the internationalization of industrial archaeology in Japan. In addition, Yamazaki Toshio also strongly promoted the development of technological history education at Tokyo Institute of Technology. Under his leadership, the university has gathered a large number of scholars on the history of technology and become one of the three major centers for the study of technological history in Japan, alongside the University of Tokyo and Kyoto University. Overall, Yamazaki Toshios research is devoted to reflecting on Japans development path and exploring ways to make the country realize free development, which reflects his consistent pursuit of academic freedom.
