The National Police Agency of Japan has ordered enhanced security measures at various domestic facilities in light of the recent death of Iran's Supreme Leader Ayatollah Khamenei, reportedly killed in a military attack by the United States and Israel. The announcement of Khamenei's death was made by U.S. President Donald Trump on February 28 and reported by official Iranian broadcasting. Following this incident, Iran has indicated it will retaliate against U.S. and Israeli positions in the Gulf region, raising concerns worldwide.

The police agency's directive includes precautions against potential demonstrations and illegal activities at the U.S., Israeli, and Iranian embassies in Japan, reflecting heightened tensions in the international arena. Police forces have been advised to increase the number of officers on duty, enhance patrols, and conduct inquiries of suspicious individuals near these facilities. This proactive approach is intended to prevent any violent acts or disturbances stemming from the ongoing geopolitical unrest.

With the situation evolving rapidly, the Japanese police are preparing to respond effectively to potential threats posed by the aftermath of Khamenei's assassination. This incident not only has implications for Iran and its geopolitical rivals but also may affect Japan's national security landscape, considering its relationship with the involved nations and the potential for increased anti-U.S. sentiment within certain factions in Japan's populous regions.
