Flagstone empire: Materiality and technical expertise in Japanese road construction in northeast China (1905–1945)

Abstract

Abstract This article investigates Japanese imperialism in northeast China through its road construction infrastructure projects within its railway auxiliary zone (1906–1932) and Manchuria at large (1932–1945). The materiality of roads unveils a history of how Japanese engineers adapted to local practices and absorbed local knowledge in building physical infrastructure and developing their technical expertise. These engineers engaged with local practices rooted in pre-existing social and natural environments to facilitate road construction. At the same time, in Manchuria their technical expertise in construction was built on the absorption and subsequent erasure of local workers’ vernacular craft. Rather than the physical realization of an imperialist, top-down vision of modernization, imperial infrastructure projects were in fact hybrid productions of technical expertise, and local vernacular knowledge and skills. By constructing roads, engineers helped to expand Japan’s political and economic influence in northeast China, assert domination over Chinese residential areas and business interests, and coerce Chinese subjects into complying with policies and rules issued by Japanese administrations. The materials of roads—gravel, granite flagstone, and concrete—illustrate a complex relationship between Japanese imperial agents and local environments.
