This chapter analyses Japan’s Southeast Asian security partnerships from a Southeast Asian perspective. Japan’s re-entering East Asia with a combination of increasing trading ties and economic development (ODA) initiatives in the 1970s and 1980s, slowly furthered economic growth and prosperity in many East-Asian countries as well as Japan - a mutually beneficial relationship that largely remained un-securitized. Beginning with the second Abe administration in 2012, Japan began to include security components in a number of bilateral relations with countries in the region. This chapter divides countries in Southeast Asian countries by their level of economic dependence on China and their threat perception vis-à-vis China, which is the core factor in explaining the rationale for why and how they engage with Japan, and shapes Southeast perspectives of Japanese-Southeast Asian security partnerships.
