In response to escalating tensions stemming from the U.S.-Israeli conflict with Iran, Japan has announced plans to begin releasing oil from its strategic reserves starting Monday. This move aims to mitigate the immediate impact on the nation’s energy supplies and serves as a stark reminder of the oil crises that Japan faced nearly fifty years ago. Back then, Tokyo established its national oil stockpiling system to protect itself from future disruptions, particularly those linked to geopolitical instability in the Middle East.
As the conflict has disrupted oil shipments through the crucial Strait of Hormuz, gasoline prices across Japan have started to climb, raising concerns about fuel availability and economic stability. To counter this, the Japanese government has committed to releasing a record 80 million barrels of crude oil from its reserves. This quantity equates to approximately 45 days’ worth of oil consumption for Japan, a country heavily dependent on imports due to its limited domestic energy resources.
Authorities have directed the nation’s refiners to utilize the crude oil being released, which will reduce Japan’s national reserves by roughly 17%. This strategic deployment is intended to secure domestic fuel supplies and prevent further price surges. However, it remains unclear how much of this oil will contribute to the broader international effort led by the International Energy Agency (IEA), which is coordinating a global release of 400 million barrels to stabilize markets affected by the ongoing conflict.
Experts emphasize that while Japan’s release of oil reserves can help stabilize supply and temper price volatility in the short term, it primarily serves as a temporary buffer rather than a long-term solution. Yuriy Humber, CEO of the Tokyo-based consultancy Yuri Group, highlighted that these reserves are crucial for buying time amid supply shocks but cannot fully compensate for a prolonged disruption in the Strait of Hormuz, a vital artery for global oil transportation.
In addition to the 80 million barrels from Japan’s own stockpiles, there is potential for further releases from approximately 12 million barrels of oil held jointly by Saudi Arabia, the United Arab Emirates, and Kuwait within Japan’s reserves. The Ministry of Economy, Trade and Industry (METI) has confirmed that these volumes would be supplementary to the announced release, underscoring the collaborative efforts among oil-producing nations to stabilize the market.
Japan’s strategic petroleum reserve system dates back to 1978, a few years after the Arab oil embargo of the early 1970s exposed the vulnerabilities of energy-dependent nations. Today, Japan maintains reserves sufficient to cover 254 days of consumption, reflecting its continued reliance on Middle Eastern oil, which accounts for about 90% of its imports. The upcoming release will include 15 days’ worth of oil from private-sector stockpiles starting Monday, followed by a month’s supply from government reserves later this month, as outlined by METI.
Meanwhile, Japan is actively seeking to diversify its oil supply sources to reduce dependence on the volatile Strait of Hormuz. METI Minister Ryosei Akazawa has indicated that the country is exploring procurement options from the United States, Central Asia, South America, and Gulf nations capable of delivering oil through alternative routes. This strategic shift reflects Japan’s broader energy security strategy, especially after it largely ceased oil imports from Russia following Moscow’s invasion of Ukraine in 2022—a period when Tokyo last tapped into its reserves.
On the other side of the Pacific, U.S. officials have underscored the importance of domestic energy production amid global uncertainties. Lee Zeldin, Administrator of the U.S. Environmental Protection Agency, remarked that despite the ongoing conflict in the Middle East, crude oil shipments from Alaska to Japan have historically remained secure from terrorist attacks. He emphasized that the current situation serves as a reminder to Indo-Pacific nations of the reliability of U.S. energy resources and the strategic advantage of sourcing oil domestically or from allied partners.
As the geopolitical landscape continues to evolve, Japan’s decision to release oil reserves highlights the delicate balance between managing immediate energy needs and pursuing long-term supply diversification. The coordinated international response, including the IEA’s planned release, reflects the global community’s recognition of the critical role energy security plays in maintaining economic stability amid conflict.
