Trade in the Japanese Empire

Abstract

Insecurity and inequality (both real and perceived) have defined the Japanese Empire as an entity of trade. If one the primary goals of Japan’s leaders during the Meiji period (1868–1912) was to revise the so-called unequal treaties, then having an empire was seen as a necessary means towards achieving this end. From the very beginning, strategic concerns proved inseperable from economic considerations. Imperial expansion into neighboring territories occurred simutaneously and worked hand in hand with forging an industrial nation-state. The empire began with the so-called internal colonization of Hokkaidō and then the Ryūkyū Islands (Okinawa), followed by Taiwan and Korea, spoils of victory after the Sino-Japanese and Russo-Japanese Wars, respectively. Taiwan and Korea represented Japan’s formal empire, and Japan developed these territories primarily as agricultural appendages—unequal and exclusive trading partners to provide foodstuffs for a growing, industrializing population in the home islands. As Japan developed its formal colonies toward a goal of agricultural self-sufficiency, it also pursued informal empire in China, which took shape as a competitive yet cooperative effort with other Western imperial powers under the treaty port system. World War I represented a turning point for imperial trade: At this time, Japan took advantage of a Europe preoccupied with internecine battles to ramp up the scope and scale of industrial production, which made Japan increasingly reliant on China—and particularly Manchuria—for raw materials necessary for heavy industry such as coal and iron. Japanese efforts to tighten its grip on China brought it into conflict with the Western imperialist powers and with a strengthening Chinese nation. Another major turning point was Japan’s 1931 takeover of Manchuria and the establishment of the puppet state of Manchukuo; these actions ended the treaty port system and sparked conflicts between China and Japan that broke out into full-out war by 1937. Although Japan was largely able to achieve agricultural self-sufficiency by the 1930s, it was unable to be fully self-reliant in essential resources for industry (and war) such as oil, tin, and iron. Resource self-sufficiency was a major goal for the construction of the Greater East Asia Co-Prosperity Sphere in the early 1940s. The Japanese Empire officially ended with defeat in 1945.
