The year 1931 stands as a major turning point in Japan���s modern history. In September 1931 Japanese armed forces overran Manchuria, committing their government to a course of direct action in Asia and, ultimately, to the rejection of the structure of international relations which had emerged in the 1920s. By 1940 Japan was caught up in a cycle of extreme nationalism, isolation, and ultimately war with the United States. This archive charts a key decade in U.S.-Japanese relations. It is is one of three digital collections based on the microfilm title Records of the U.S. Department of State Relating to United States Political Relations with Japan, 1930-1954.
