Japan has begun releasing oil from its strategic national reserves in response to escalating fuel prices triggered by the Iran crisis and the effective blockade of the Strait of Hormuz. The government initiated the release on March 26, 2026, from eleven storage facilities across the country, according to NHK. The release represents the largest-ever deployment of Japan's petroleum reserves, combining both national stockpiles held by the government and mandatory commercial reserves held by private companies. This emergency measure aims to stabilize domestic fuel supplies as tensions in the Middle East disrupt global oil markets and maritime shipping routes. The crisis has already produced dramatic price increases for consumers and businesses across Japan. Kyoto City's Transportation Bureau faced particularly stark evidence of the market disruption when its regular bidding process for diesel fuel failed entirely. The bureau was forced to enter into a negotiated contract at approximately 216 yen per liter—roughly double the 108 yen per liter price paid in March for fuel delivered that month, according to NHK reporting. For ordinary consumers, gasoline prices have also surged, though government intervention has provided some relief. As of March 23, regular gasoline averaged 177.7 yen per liter nationwide, down 13.1 yen from the previous week's record high. This decrease reflects the impact of enhanced government price mitigation measures implemented on shipments from March 19, NHK reported. However, prices remain significantly elevated compared to pre-crisis levels. The situation has created serious challenges for Japan's maritime industry. According to Nagasawa, chairman of the Japan Shipowners' Association, approximately 45 Japanese-affiliated vessels remain stranded in the Persian Gulf due to the ongoing Strait of Hormuz blockade. Speaking at a March 25 press conference, Nagasawa reported that Japanese vessels and crew members trapped in the Persian Gulf have not suffered serious harm and remain in regular contact. The association is working to find solutions that would allow passage through the strait. Recognizing the potential for prolonged disruption, Prime Minister Takaichi met with Fatih Birol, Executive Director of the International Energy Agency (IEA), during his visit to Japan. According to NHK, Takaichi requested that the IEA prepare for additional coordinated releases from member countries' strategic petroleum reserves. The prime minister emphasized the need for preparedness in case the crisis extends over a longer period. Economy, Trade and Industry Minister Akazawa separately met with Birol to stress the global implications of fuel shortages in Asia. Akazawa requested that the IEA consider coordinated reserve releases, noting that petroleum product shortages in Asia would significantly impact global manufacturing supply chains, according to NHK. Global oil markets have responded with volatility to the unfolding crisis. On March 24, the West Texas Intermediate (WTI) crude oil futures price—a key international benchmark—experienced sharp drops on the New York Mercantile Exchange, demonstrating the market instability surrounding the Iran situation, NHK reported. For foreign residents in Japan, the immediate impacts are visible at the pump and potentially in transportation costs. While government price mitigation measures have temporarily cushioned the blow for gasoline consumers, the doubling of diesel prices seen in Kyoto's experience could eventually affect public transportation fares and delivery costs for goods. The Japanese government's decision to tap strategic reserves—resources typically held for genuine emergencies—underscores the seriousness with which officials view the current situation. These reserves exist precisely for scenarios like the present crisis, where Japan's heavy dependence on Middle Eastern oil imports creates vulnerability to regional instability. As the situation develops, expats should monitor fuel prices and be prepared for potential increases in transportation and shipping costs if the crisis continues or intensifies.
