軍事視角下的當代沖繩地緣政治角色：以地緣政治結構理論為例

The Contemporary Geopolitical Role of Okinawa from a Military Perspective: A Case Study Based on Geopolitical Structural Theory

近年來隨著中國軍力增強造成的東亞地區安全環境的變化，日本逐步增強自衛隊在沖繩的軍事力量，同時這樣的過程也得到來自美軍提供的協助，成為美日安保合作下的重點區域。本研究期望透過運用地緣政治學者Saul B. Cohen的「地緣政治結構」（Geopolitical Structure）之理論架構，分析理論中「海洋性」對於日本軍事戰略的影響。並以近年來日本自衛隊對於沖繩的軍事建設內容為對象，從中觀察地緣政治結構影響在其中的反映，以釐清當代日本對於沖繩防衛建設的戰略視角與思考。

In recent years, changes in the security environment of East Asia caused by China’s growing military power have led Japan to gradually strengthen the Self-Defense Forces’military presence in Okinawa. This process has also received support from the U.S. military, making Okinawa a key area of U.S.-Japan security cooperation. This study aims to analyze the influence of“maritimity”on Japan’s military strategy within the framework of geopolitical scholar Saul B. Cohen’s“geopolitical structure”theory. By examining recent military developments of the Japan Self-Defense Forces in Okinawa, this research seeks to observe the reflection of geopolitical structural influences and clarify Japan’s strategic perspectives and considerations regarding Okinawa’s defense construction in contemporary times.
