The paper titles “An Assessment of Japan-Germany Relations in the Post Cold War Era”, is an attempt to examine the foreign policy behaviour of Japan and Germany and its implications at the international scene. As indicated in the title, the scope of this paper is restricted to a definite timeline of world history. The year 1990 resonates several episodic changes in world politics, notably the unification of Germany, the disintegration of the Soviet Union, the end of the cold war, the release of Nelson Mandela from prison, the resignation of Margaret Thatcher, the foundation of the World Wide Web, the formal beginning of the Human Genome Project, the beginning of an era of neo-liberal economic policies in India, the emergence of coalition politics in Japan, etc. It is amidst all such epoch-making events in the year 1990, this paper attempts to explore the new dimensions of Japanese foreign policy towards a unified Germany since 1990. The ambit of the paper includes understanding Japan and Germany as actors in the international politics, how the two nation states behave with each other and with the other state and non-state actors, and how their behaviours have implications at the regional, multilateral and global fronts. This paper primarily focuses on the political and economic aspects of these two countries to arrive at their understanding of international cooperation and inter-dependence.
