Japan has formally asked Saudi Arabia to increase crude oil supplies as the country seeks to secure stable energy imports amid ongoing disruptions to global shipping routes and heightened uncertainty in the Middle East.

The request was made during a telephone call between Japanese Prime Minister Sanae Takaichi and Saudi Crown Prince Mohammed bin Salman.

According to official statements reported in multiple contemporaneous accounts, Tokyo expressed appreciation for existing Saudi deliveries while urging cooperation to expand volumes sent to Japan.

Saudi Arabia responded by indicating it would consider the request positively and reaffirmed its willingness to work with Japan to ensure stable energy flows.

What is confirmed in both sides’ statements is that the discussion focused not only on immediate supply volumes but also on broader energy security cooperation and regional stability.

The talks come at a time when Japan is highly exposed to Middle Eastern oil supply chains.

The country imports the vast majority of its crude from the region, and shipping flows have been strained by heightened geopolitical tensions that have affected key maritime chokepoints.

Japanese officials have separately emphasized the importance of maintaining safe navigation routes and reducing dependence on vulnerable transit corridors.

Beyond supply requests, the two leaders also discussed broader strategic cooperation, including efforts to stabilize regional tensions and strengthen bilateral coordination in areas such as energy security and economic ties.

Some reporting also indicates parallel discussions about diversifying shipping routes, including the use of alternative pathways through Red Sea-linked infrastructure, though the operational scope and timing of such measures remain unclear.

Japan has already taken additional steps to cushion potential supply shocks, including drawing on strategic petroleum reserves and coordinating with international partners on emergency oil stockpile mechanisms.

These measures reflect concerns that sustained disruption in Middle Eastern supply routes could tighten global markets further and increase volatility in energy prices.

What remains unclear is whether Saudi Arabia will meaningfully increase export volumes in the near term, or whether any expansion will be gradual and tied to broader market conditions and production policy within OPEC+.

No binding commitments on additional shipments have been publicly confirmed.
