In this paper we shall try to do three things: first, to describe the economic conditions which prevailed before the arrival of Commodore Perry; second, to survey the economic policy of the Shogunate and the Meiji Government in responding to the impact of the opening up of the country; and third, to make a few general comments on some selected aspects of Japan's economic development between 1859, when three Japanese ports were opened to foreign trade, and 1894, when the Sino-Japanese War broke out. The latter date is chosen because it fairly clearly marks off the beginning of the rapid development of the modern sector of the Japanese economy.
