text: Yonekura shows the steel industry was central to the economic development of Japan. The nation's sudden transformation from feudal to modern society in the late nineteenth century, its heavy industrialization and imperialist war ventures in 1900–1945, and the post-World War II high-economic growth, all depended on iron and steel.  The other great Japanese industries, such as shipbuilding, automobiles, and industrial machinery are closely linked to steel. From 1850 to 1970, the industry increased its crude steel production from virtually nothing to 93.3 million tons (the third largest in the world).
  The government's activist Ministry of International Trade and Industry (MITI) played a major role in coordination. The transfer of technology from the West and the establishment of competitive firms involved far more than buying foreign hardware. MITI located steel mills and organized a domestic market; it sponsored Yawata Steel Company. Japanese engineers and entrepreneurs internally developed the necessary technological and organizational capabilities, planned the transfer and adoption of technology, and gauged demand and sources of raw materials and finances.
