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].

Core Viewpoint - The article discusses the potential implications of the Iranian blockade of the Strait of Hormuz on Japan's energy security, highlighting the legal framework for Japan's collective self-defense and the historical context of similar situations [2][4][6]. Group 1: Legal Framework and Collective Self-Defense - The concept of "existential crisis situation" was established during Shinzo Abe's administration in 2015, allowing Japan to exercise collective self-defense under specific circumstances [4]. - An "existential crisis situation" is defined as a state where Japan's survival is threatened due to military attacks on closely related countries [4]. - The Japanese government has previously considered the blockade of the Strait of Hormuz by mines as a potential scenario for exercising collective self-defense, although it has never been enacted [2][4].
