Mechanical Power in the Industrialization of Japan

Abstract

The rapid industrialization of pre-war Japan depended upon extensive use of mechanical power. This dependence is studied quantitatively based on historical statistics of power for the years from 1890 to 1940. The introduction of engines (the change from human to mechanical power) and shifts in the kinds of engines (from water wheels to steam engines to electric motors) are clarified by industry group. The impact of these changes on technological progress in manufacturing is revealed.
