摘要:The Japanese Armed Forces did not take a long time to occupy the southern regions. Invading the southern regions was the Japanese’s ambition to build “The Greater East Asia Co-Prosperity Sphere”. Through Kalijati treaty, the Government of Dutch East Indies declared its unconditional surrender to the Japanese Armed Forces. Banyuwangi is an area located in the most eastern part of Java and considered as a strategic place as a defense fortress for all Java regions from the allied attacks from the south (Australia). The Japanese 16th Army implemented various policies as a part of the Greater East Asia War plan. The purpose of this study was to describe the policies made by the Japanese military government when occupying Banyuwangi, East Java. This study used a historical research method consisting of five steps: topic selection, heuristics, criticism, interpretation, and historiography. The result of this study shows that Banyuwangi is a strategic area where the Japanese 16th Army directly or indirectly implemented various policies for mass mobilization in supporting the Greater East Asia War. Through its propaganda, the Japanese military said that the Banyuwangi people’s sacrifice was for a mutual victory in the war to build a new, safe, and prosperous Asia.
