Industry moves into waterfront areas during postwar reconstruction
After the Pacific War ended on 14 September, 1945, the Allied Forces ordered the rehabilitation and extension of runway A at Haneda airfield. This was soon followed by a succession of new projects, such as dredging of Niigata Port for the Ministry of Transport and land reclamation at the Miike mine in Omuta for Mitsui Mining, as TOA Kowan Kogyo successfully rode the wave of postwar reconstruction demand in Japan.
HISTORY
First phase of the land reclamation boom
The rapid domestic economic growth that began in the late 1950s prompted a spate of port and harbour projects and associated waterfront land reclamation works from 1958 onwards, and ushered in a key growth period for the reclamation and dredging industry. TOA Kowan Kogyo was able to build more pump dredgers and invest in new equipment, while the increased revenue helped to generate extra capital for the company.
HISTORY
Land reclamation went nationwide
The 1962 Law to Promote the Establishment of New Industrial Cities generated fresh demand for waterfront land development, and TOA Kowan Kogyo was engaged in a number of projects including preparation of an industrial site for Kawasaki Steel at Mizushima in Okayama Prefecture, dredging of navigation channels for Mitsubishi Oil, and development of a waterfront industrial site for NKK at Fukuyama. The Company was also contracted for national projects such as the Kashima waterfront industrial precinct, which involved dredging of the central channel and construction of southern breakwaters.
HISTORY
Fiscal consolidation and corporate management plan
The Izanagi boom saw a sustained period of economic growth lasting for 56 consecutive months from late 1965 through to 1971, which brought high levels of investment in port and harbour development. However, during this time, the Company became more engaged in general civil engineering projects than dredging operations. Corporate management had moved on to capitalise on government economic policy.
HISTORY
Company expanded into land-based prijects and seeked to become a general civil engineering company
The formation of the Kakuei Tanaka cabinet in July 1972, on the back of a grand plan for remodeling the Japanese archipelago, led to yet another development boom and prompted TOA Kowan Kogyo to expand beyond port and harbour development into general civil engineering projects such as roads, bridges, building foundations and submerged tunnels, as well as residential land development over sea and land areas and even maritime developments.
