Abstract
This paper aims to focus on the historical relationship of the Japanese occupation in East Sumatra and South Sumatra. Various policies continued to be implemented in accordance with the conditions of war at that time. For three and a half years, the policies carried out were to provide land for planting food commodities, mobilisation of Romusha, giving opportunities for figures to occupy important positions in the government until the promise of independence for Indonesia. After Indonesia’s independence (1945), a new round of Indonesian- Japanese relations began. The relationship between the two countries became collaborative and more fluid, and continued to develop until the present day. Japan remains one of Indonesia’s important partners in various fields, especially in the field of economy trade
