Japan to Tap State Reserves Again, Releasing 20 More Days of Oil in May

The Japanese government will release an additional 20 days' worth of oil reserves beginning in early May, a follow-up measure to a March drawdown intended to address supply uncertainty arising from the war in the Middle East. The March release amounted to roughly 50 days of supply and drew on a mix of government holdings, private sector stocks and reserves held by Gulf producers. As of April 6, Japan's total reserves stood at 230 days, including 143 days in government stockpiles.

Key Points

Japan will release 20 days' worth of oil reserves in early May to address supply uncertainty linked to the war in the Middle East.
An earlier March release tapped roughly 50 days of supply from government holdings, private sector stockpiles and reserves held by Gulf nations.
As of April 6, total oil reserves in Japan equaled 230 days' worth of supply, with 143 days held in government stockpiles - actions that affect the energy sector and markets tied to oil supply.

Japan will carry out a second round of oil reserve releases starting in early May, with the government set to put an extra 20 days' worth of crude onto the market, Prime Minister Sanae Takaichi said. The move is aimed at addressing supply uncertainty stemming from the war in the Middle East.

This planned release follows an earlier step in March when Japan made available roughly 50 days' worth of oil. That initial drawdown drew on a combination of state-held reserves, private sector stockpiles and reserves provided by oil-producing Gulf nations, according to government descriptions at the time.

Official data reported by the Natural Resources and Energy Agency indicate that as of April 6 Japan held the equivalent of 230 days' worth of oil reserves. Of that total, 143 days' worth were held in government stockpiles.

The May release is intended to begin in the first part of the month and represents a targeted, time-limited measure. The authorities framed the second release as a continuation of steps taken last month to respond to the supply uncertainty attributed to the conflict in the Middle East.

Details provided by officials describe the sources tapped for the March release as a mix of government holdings, private inventories and stockpiles held by Gulf oil producers, underscoring a multi-faceted approach to managing short-term availability.

Public figures cited by the energy agency describe the country's reserve position in terms of days of supply rather than volumes of crude, with the aggregate figure of 230 days combining diverse categories of reserves. The government-held component of that total accounts for 143 days.

Tokyo's decision to schedule an additional 20-day release in May is presented as a reactive measure to ongoing supply uncertainty. Officials have specified the timing as early May and have linked the step directly to efforts begun last month.

Data snapshot

March release: about 50 days' worth of oil tapped from various reserves.
Planned May release: an additional 20 days' worth of reserves, to begin in early May.
Reserves as of April 6: 230 days' worth total, including 143 days in government stockpiles.

Risks

Ongoing supply uncertainty due to the war in the Middle East, which is the stated reason for the reserve releases - this primarily affects the energy sector and markets reliant on crude oil.
Repeated use of reserves to manage short-term supply disruptions could alter the composition of state and private stockpiles, creating uncertainty for supply planning in energy and transport sectors.
