Early in the Japanese era, Taiwan was treated as a production site for tropical cash crops and grains. Taiwan’s agriculture, forestry, and fishery resources were systematically developed to supply Japan’s needs. In regards to industrial development, colonial Taiwan mainly focused on new sugar manufacturing and food processing. In late 1930s, the Governor-General’s Office proposed to industrialize Taiwan; during wartime, various armaments industries were also developed, which also helped lay the foundations of Taiwan’s industrialization. Throughout the island, both industrial and transportation infrastructure gradually became more complete. With a comprehensive transportation system and public order, tourism slowly developed. To showcase its achievements in developing its colony, the Empire of Japan held many large-scale expositions, in which Taiwan’s industries and products received considerable promotion.
