History

Santaro Kumagai, the company's founder, began his career as a civil servant in a police department. His construction career started as a stonemason, crafting religious monuments and performing work for the expanding railway network.^[3]

Kumagai founded his own company in 1898 and incorporated it in 1938. Between 1955 and 1983 the company accounted for more than 10% of all contracts awarded to the fifty-seven members of the Overseas Construction Association of Japan, a figure that outranked the ‘Big Five’ domestic giant construction companies.^[4] As overseas projects were riskier, these five companies were reluctant to expand beyond Japan. Kumagai Gumi took advantage of the situation and sought work overseas, as both as a construction company and a developer, using BOT as project financing, becoming one of the leading proponents of BOT in Southeast Asia. By 1985 overseas earnings amounted to 46% of Kumagai's total contracts.^[5]

In the 1980s the company became the largest Japanese real estate investor in New York City,^[6] investing in projects in Manhattan, including in projects developed by William Zeckendorf Jr.^[7]
