This article aims to explore the Japanese colonial government’s efforts to promote mass movements in Korea which rose suddenly and showed remarkable growth throughout the 1930s. It focuses on two Governor-Generals and the directors of the Education Bureau who created the Social Indoctrination movements under Governor-General Ugaki Kazushige in the early 1930s and the National Spiritual Mobilization Movement of Governor-General Minami Jirō in the late 1930s. The analysis covers their respective political motivations, ideological orientation, and organizational structure. It demonstrates that Ugaki, under the drive to integrate Korea with an economic bloc centered on Japan, adapted the traditional local practices of the colonized based on the claim of “Particularities of Korea,” whereas the second Sino-Japanese War led Minami to emphasize assimilation, utilizing the ideology of the extended-family to give colonial power more direct access to individuals as well as obscuring the unequal nature of the colonial relationship. It argues that the colonial government-led campaigns constituted a core ruling mechanism of Japanese imperialism in the 1930s.
