This working group will collect, compile, and publish historical materials while examining the state of postwar Japanese politics and diplomacy as a free and democratic nation. In particular, the group will focus on Japan's return to the international community in the 1950s, and analyze how Japan developed its political, diplomatic, and security policies.

This unit will examine the role of Japan’s diplomacy in the current state of international affairs. In this era of "interstate competition" between major countries and advanced nations, especially the West and authoritarian states such as China and Russia, what kind of ideological underpinnings should Japan base its diplomacy on? This study group will examine Japan's historical developments and the nature of its value-oriented diplomacy.

This unit was established to complement the activities of the research group 'Historical Studies on Postwar Japanese Diplomacy' from the perspective of political history.

In this research unit, experts from various regions come together to investigate and conduct research on the role of leadership in international politics.
