霍尔木兹海峡封锁，日本直面“存亡危机”？

Core Viewpoint - The article discusses Japan's strategic response to the potential blockade of the Strait of Hormuz by Iran, emphasizing the importance of this waterway for Japan's energy imports and the implications for Japan's collective self-defense policy [1][3]. Group 1: Strategic Importance of the Strait of Hormuz - The Strait of Hormuz is critical for Japan, with over 90% of its crude oil imports coming from the Middle East, and approximately 80% of oil tankers passing through this strait [1]. - The Japanese government has previously considered a blockade of the strait as a scenario that could trigger the exercise of collective self-defense under its security laws [1]. Group 2: Government's Cautious Stance - The current Japanese administration, led by Prime Minister Kishi Nobuo, is taking a cautious approach, stating that it is still gathering information and has not yet classified the situation as a significant security threat [3]. - Historically, Japan has never activated collective self-defense in response to threats to resources from the Strait of Hormuz, indicating a high threshold for such a decision [3][4]. Group 3: Potential Future Developments - If the situation escalates to a blockade involving mines, the U.S. may seek Japan's assistance for mine-clearing operations, presenting a significant test for the current administration's security policy since the enactment of the security laws [4].
