## Company history

Founded in October 1873 by Kihachiro Okura as Okura Gumi Shokai, Taisei traces its origins to a business involved in trade, civil engineering and building construction. Its early history includes the establishment of Nippon Doboku Co. in 1887, described in the company chronology as Japan’s first construction-industry corporation, and the incorporation of Okura Doboku Gumi in 1917. Early landmark works included the Rokumeikan and Lake Biwa Lock and Tunnel. [22](https://www.taisei.co.jp/corp/ayumi/150th/en/history/founder.html) [6](https://www.taisei.co.jp/english/profile/history/chronology/)

The company adopted the name Taisei Corporation in 1946 and established a research institute in 1960. Its subsequent project history includes major Japanese infrastructure works such as the Seikan Tunnel, Seto Ohashi Bridge, Akashi Kaikyo Bridge and Tokyo Bay Aqua-Line, as well as urban developments including Yokohama Landmark Tower and Tokyo International Forum. Taisei later expanded its group through the 2009 conversion of Taisei Rotec into a wholly owned subsidiary and its 2023 acquisition of Satohide Corporation.
