Abstract: During the First World War, Japan occupied the Micronesia（South Sea Islands）,which originally belonged to Germany. In 1922，Japan officially established the Nanyo Cho and began to implement civil colonial rule.Nanyo Kohatsu Kabushiki Kaisha was formally established in November 1921. With the support of Nanyo Cho，Nanyo Kohatsu Kabushiki Kaisha promoted the colonial industry construction with the sugar industry as the center. It has experienced the entrepreneurial stage in the 1920s，the expansion to other Pacific islands in the 1930s and the decline in the 1940s. Nanyo Kohatsu Kabushiki Kaisha assisted the Japanese government to consolidate the colonial rule in the Micronesia and assisted the Japanese navy to participate in the Pacific War from beginning to end. It is a company serving the external expansion of modern Japanese imperialism.
