戰後七十年，國際格局與日本對外戰略都面臨著重大的方向轉換。目前日本正在嘗試進行的戰略調整與國際社會的發展趨勢之間正呈現不同的趨向。日本將新的「安保法制」置於日本國家對外戰略調整的首要位置，一定程度上也體現了日本對國際格局的理解和國家志向的核心本質。日本外交戰略的調整，在不同時期有不同的取向，很大程度上與日本國內政治相關。在日本對外戰略的繼承與變革方面，作為日本外交基軸的日美同盟發揮著關鍵性的作用。

Seven decades since the Second Great War, both the international order and Japan's foreign strategy face major shifts in direction. In relation with the development of the international society, Japan's strategic adjustment is moving in the opposite direction. To a certain extent, the fact that Japan has placed its priority in the Japan-US security alliance demonstrates Tokyo's understanding of international order and the essence of its vision for the future. Noting Tokyo's different policy orientation in different period, the adjustment of Japan's foreign policy strategy is greatly connected with the country's domestic politics. The Japan-US alliance plays an important role in the development of Japan's foreign policy strategy.
