Japan Launches Second Round of National Oil Reserve Releases Amid Middle East Tensions
5/4/2026, 5:44:33 AM
Second Release of Strategic Petroleum Reserves
On May 1 2026, the Japanese government commenced a second round of releases from its national petroleum stockpiles, delivering a total of 5.8 million kiloliters of oil—an amount estimated to cover roughly 20 days of domestic consumption. The oil is being drawn from ten stockpiling bases across the country, including the Shibushi National Petroleum Stockpiling Base in Kagoshima Prefecture and a base in Ibaraki Prefecture. Four domestic wholesalers are purchasing the released oil for an estimated 540 billion yen. The plan also calls for releasing reserves held by the private sector and supplementing the supply with oil procured from the United States.
Background: Strait of Hormuz Blockade and Energy-Security Concerns
In early 2026, escalating tensions in the Middle East effectively shut down the Strait of Hormuz, a critical maritime conduit for crude oil. The de facto blockade caused a sharp drop in Japan’s recent crude-oil imports, prompting concerns about the nation’s ability to procure sufficient fuel for domestic use. A prior drawdown of reserves in March 2026, amounting to about 30 days of consumption, was undertaken to mitigate the same risk.
Key Figures & Groups
- Prime Minister Sanae Takaichi announced on 10 April 2026 that an additional release, equivalent to roughly 20 days of national consumption, would be carried out in May.
- The Agency for Natural Resources and Energy coordinates the releases.
- A government spokesperson addressed operational issues related to the release schedule.
- Four domestic wholesalers are the designated purchasers of the released oil.
Timeline of Decisions and Deployments
- 26 March 2026 – First release of national reserves, covering approximately 30 days of consumption.
- 10 April 2026 – Prime Minister Takaichi announces a planned May release of additional reserves.
- Late April 2026 – Government announces a one-day postponement of the start date, citing information-sharing gaps.
- 1 May 2026 – According to one report, the second round begins as scheduled.
- 2 May 2026 – Loading of oil onto tankers begins at Shibushi Base, Kagoshima Prefecture (per another report).
- 3 May 2026 – Media reports state the second round officially commenced nationwide.
Data & Statistics
- Volume released: 5.8 million kiloliters.
- Coverage: Approximately 20 days of Japan’s domestic oil consumption.
- Purchasers: Four wholesalers, paying about 540 billion yen.
- Infrastructure: Releases from ten stockpiling bases, including Shibushi (Kagoshima) and Ibaraki locations.
- Supply outlook: Combined with the March drawdown, the government expects sufficient oil to last until after the start of the following year.
Official Statements & Government Response
Prime Minister Takaichi’s April announcement framed the May release as a pre-emptive measure to safeguard energy stability amid Middle-East disruptions. A government spokesperson later acknowledged that inadequate information sharing by the Agency for Natural Resources and Energy caused a scheduling mix-up, and pledged to improve inter-agency communication. The administration emphasized that the combined releases, together with privately held reserves and U.S.-sourced oil, are intended to ensure a stable domestic supply.
Conflicting Reports & Gaps
Sources differ on the exact commencement date of the second release, citing either 1 May or 2–3 May. Location details also vary, with one account highlighting an Ibaraki base and another focusing on the Shibushi base in Kagoshima. No public criticism or opposition to the releases was identified in the available reports.
Why It Matters: Energy Stability and Geopolitical Implications
The releases directly address Japan’s vulnerability to supply interruptions caused by the Hormuz blockade, aiming to maintain uninterrupted fuel availability for households and industry. By drawing on strategic reserves and diversifying supply sources, the government seeks to reduce immediate reliance on volatile shipping routes and to sustain economic activity through the projected supply horizon.

What's Next
The Japanese government will continue to monitor the situation in the Strait of Hormuz and adjust reserve management as needed, with the current stockpiles expected to sustain the nation beyond the start of the next calendar year.
