The name was changed to Tokyo Institute of Technology in 1901 and then Tokyo Institute of Technology, a public university in 1929.
From 1945 Become the current Tokyo Institute of Technology university.
The founder of NSK Ltd.Nippon Seiko-Sya), Takehiko Yamaguchi, graduated from Tokyo Institute of Technology (currently Tokyo Institute of Technology) in 1891 (Meiji 24) and at the same time worked for the patent office of the Ministry of Agriculture and Commerce. Therefore, while in charge of the machine review, he was interested in the machine industry in the developed countries of Europe and the United States. (Meiji 28), ordered Yamaguchi to visit the West for that purpose. Yamaguchi, who visited factories in Europe and the United States and returned home two years later, realized that Japan’s technological level was far behind that of Europe and the United States, and in 1906 (Meiji 39) Established Yamatake Shokai, an import machinery trading business. Later, on February 20, 1914, the Nippon Seiko Joint Stock Company was established mainly to produce bearings that are most needed in the machine industry.
