During a press conference on October 2nd, Japan's Chief Cabinet Secretary, Hirokazu Matsuno, was questioned regarding the military attacks on Iran carried out by the United States and Israel. He stated that Japan is not in a position to make a definite legal assessment of the situation as they do not have detailed information on the facts. Matsuno emphasized Japan's intention to work closely with related countries to gather information and respond effectively in order to ensure the early stabilization of the situation.

Regarding the evacuation of Japanese nationals in the region, Matsuno indicated that the Japanese embassy in Israel plans to operate buses for evacuation as early as the same day in Japan's local time. He mentioned that Japan's Self-Defense Forces are also prepared to be deployed rapidly to assist with transportation for those requiring evacuation. This swift response highlights Japan's commitment to the safety of its citizens amid escalating tensions in the region.

Additionally, Matsuno addressed concerns about potential impacts on Japan’s oil supply due to shipping disruptions in the Strait of Hormuz, where vessel traffic has been halted. He reported no immediate impacts on Japan’s oil supply, outlining that the country has sufficient reserves, including 146 days’ worth in national stockpiles and an additional 101 days from private reserves, which total a robust 254 days of supply. He also clarified that there are currently no plans to release oil stockpiles, indicating preparations are in place to ensure a steady supply amid geopolitical tensions.
