Abstract: Given the crucial geopolitical position of the Eastern Mediterranean region, Japan has taken the opportunity to strengthen its diplomacy towards the region in recent years. Japan’s diplomacy in the Eastern Mediterranean region focuses heavily on promoting the resolution of hot and difficult issues in the region, maritime cooperation, energy cooperation, refugee assistance, and non-traditional security issues. While continuing to consolidate and deepen relations with important countries in the Eastern Mediterranean region, Japan has also gradually expanded its diplomacy with less influential countries such as Tunisia, Libya, and Syria in recent years. Japan’s continuous strengthening of diplomacy towards the Eastern Mediterranean region can be analyzed and interpreted from various aspects such as seeking geopolitical interests and demonstrating global influence. Due to various constraints, Japan’s diplomacy in the Eastern Mediterranean region will face some challenges and problems in the future.
