大成建設(株)『大成建設のあゆみ』(1969.05)

Originally from Echigo (present-day Niigata prefecture), Okura Kihachiro (1837-1928) directed his attention to foreign trade in Tokyo before and after the Meiji Restoration and founded the Okuragumi Shokai Company in 1873. He was also involved in the construction industry, and in 1887 established the Nippon Doboku Co., Ltd (Shibusawa Eiichi served as chairman). In 1893 he established the Okura Doboku Gumi Corporation and responded to the needs of the times by constructing railways and harbors. The company changed names several times and, with the dissolution of the zaibatsu after World War II, became the Taisei Corporation in 1946. The first half of the shashi summarizes the history of the company from its inception and the second half summarizes the history of overseas expansion, changes in construction technologies, and the development of new technologies.
