Toyo Construction Co., Ltd. (1890.T) Bundle
From its origins as Hanshin Harbor Construction on July 3, 1929 to its 2025 integration into Taisei Corporation, Toyo Construction has carved a niche in marine and civil engineering, completing over 1,200 major projects valued at more than ¥1.5 trillion (≈$13.7B) and reporting ¥278.0 billion in net sales with a consolidated net income of ¥2.0 billion in 2024; the company-whose largest pre-acquisition shareholder was Maeda Corporation at 20.19%-became a Taisei subsidiary following a tender offer valuing the deal at approximately ¥160 billion (¥1,700 per share), a move that folds Toyo's strengths in ports, dredging and marine infrastructure into Taisei's broader platform and helps explain how its four-segment business (Civil Engineering, Building Construction, Overseas Construction and Real Estate) turns contracts, leases and specialized marine expertise into diversified revenue streams while positioning the combined group for an estimated consolidated revenue near ¥2.32 trillion in the post-acquisition landscape.
