Abstract
In the early Meiji era, the western civilization was flowed into Japan, and the flow of civilization could be established. In the field of the electricity the electric telegraph and the electric light have spread nationwide. These were accomplished by a flow of academic cultivation planted in the Edo period. In the Kyoho five years (in 1720), in order to improve the promotion of the encouragement of new industry and medical technology, Shogun Yoshimune Tokugawa removed an embargo on importation of the Netherlands books unrelated to Christianity. Natural Science technology in Western Europe was coming in and the electrical engineering was starting. So in this paper we describe the electrical machinery technology in Japan in comparison with that of Western Europe at that time of the Edo period. Many people have contributed to the formation of electrical engineering in the Edo period. It is considered that three people, Gennai Hiraga, Soukichi Hashimoto, Koumin Kawamoto especially contributed to the formation of electrical engineering. It is because we think they had many knowledge and they had made a large contribution to electrical science and engineering during the Edo period.
