The paper examines whether Shinzo Abe is the primary influence on Japan's foreign policy, particularly in light of his nationalistic views and actions regarding territorial disputes. It discusses various theories of foreign policy analysis, emphasizing the role of individual leaders' beliefs and perceptions in shaping national decisions, alongside historical parallels with past leaders. The findings suggest that Abe's personal ideologies significantly impact Japan's international relations and constitutional discussions, especially related to military engagement and historical narratives.
