Japan is now officially accelerating its strategy to diversify its crude oil import sources.
This major policy shift comes directly in response to the ongoing disruption in the Strait of Hormuz, a critical chokepoint for global oil shipments. With international oil prices like Brent crude trading above $100 per barrel and maritime security risks escalating, Japan's heavy dependence on Middle Eastern oil—which accounted for over 94% of its imports in 2025—has become a significant economic vulnerability. Prime Minister Sanae Takaichi's recent call to the cabinet to seek new suppliers is a clear signal that the government is moving from temporary crisis management to a long-term structural solution.
The government's strategy is twofold. First, it is using its massive strategic petroleum reserves as a short-term buffer. Japan holds roughly eight months' worth of reserves, and has already begun releasing them in phases. This action provides a crucial time bridge, allowing the country to meet its energy needs without immediate panic while it works on securing alternative supplies. It's a way to keep the economy running and stabilize prices at the pump, supported by gasoline subsidies.
Second, and more importantly, Japan is actively pursuing new long-term suppliers. The goal is to fundamentally rewire its procurement network away from the volatile Middle East. The United States is a prime candidate, with Japan having already laid the groundwork by doubling its intake of U.S. crude in 2025. The aim is to potentially double this share again. Beyond the U.S., Japan is also exploring options in the Americas, such as Mexico, and looking at Middle Eastern routes that bypass the Strait of Hormuz, like pipelines in the UAE and Saudi Arabia.
This pivot is about more than just barrels of oil; it's about national security and economic stability. Persistent high energy prices threaten to worsen Japan's trade deficit and fuel inflation, impacting both businesses and households. By diversifying its energy sources, Japan aims to build a more resilient economy that is less susceptible to geopolitical shocks in a single region. The Prime Minister's directive marks a decisive step from simply weathering the storm to building a stronger, more secure energy future.
- Strait of Hormuz: A narrow waterway between Iran and Oman, through which about a fifth of the world's oil supply passes, making it a critical chokepoint in global energy trade.
- Brent Crude: A major international benchmark for oil prices, used to price two-thirds of the world's internationally traded crude oil supplies.
- Strategic Petroleum Reserves: A stockpile of crude oil maintained by a country to safeguard against severe energy supply interruptions.
