Tokyo, April 25: Japan is aggressively diversifying its crude oil supply chains as the Middle East conflict intensifies, with Prime Minister Sanae Takaichi confirming that approximately 60 per cent of the country's crude oil requirements for May 2025 have been secured through routes that bypass the strategically critical Strait of Hormuz. The announcement came following a high-level Ministerial Meeting on the Situation in the Middle East, signalling Tokyo's urgency in shielding its energy-dependent economy from supply disruptions.

Japan's Alternative Crude Oil Procurement Plan

Prime Minister Takaichi, posting on X (formerly Twitter) via the PM's Office of Japan, stated that regarding alternative crude oil procurement that does not pass through the Strait of Hormuz, Japan has an outlook for securing approximately 60% for May. This is a significant strategic shift for a nation that relies on West Asia for over 90 per cent of its crude oil imports, the majority of which historically transits through the Strait of Hormuz.

The diversified supply sources now include not only the Middle East and the United States, but also Central Asia, Latin America, and the Asia-Pacific region. This geographic spread is designed to reduce single-point vulnerability in Japan's energy supply chain.

Strategic Oil Reserve Release Worth USD 3.4 Billion

In a parallel move, the Japanese government announced on Friday, April 25 that it will begin releasing additional oil reserves equivalent to approximately 20 days of supply starting May 1, 2025. This is the second such release, the first having freed up roughly 50 days worth of reserves held by both the state and private entities.

According to Japan's Ministry of Economy, Trade and Industry (METI), the second release will make available 5.8 million kilolitres of oil, valued at approximately 540 billion yen (USD 3.4 billion). The scale of this intervention underscores how seriously Tokyo is treating the energy security threat posed by the ongoing West Asia conflict.

Critical Materials: Dialysis Supplies and Agricultural Plastics Secured

PM Takaichi also addressed concerns beyond fuel, noting that dialysis tubing, a petroleum-derived medical supply that Japan imports, has been secured through the end of September 2025. This was achieved by prioritising petroleum-based materials for overseas facilities operated by Japanese companies.

Additionally, she confirmed that plastic agricultural materials including mulch sheets and rice bags needed for the spring season have been procured. Takaichi instructed the minister in charge to fully utilise the POWERR Asia framework to ensure stable supply volumes from October 2025 onward.

To address concerns about future procurement, the government will closely review supply chains and work with raw material manufacturers to ensure stable supply and prevent any disruption to food supply, Takaichi added.

Why This Matters: Japan's Structural Energy Vulnerability

Japan is one of the world's most energy-import-dependent major economies. With virtually no domestic crude oil production, the country's industrial base, transportation sector, and even food supply chains are deeply linked to uninterrupted petroleum imports. The Strait of Hormuz, through which roughly 20 per cent of global oil trade passes, represents a chokepoint that any escalation in West Asia could shut down, with catastrophic consequences for Japan's GDP and inflation.

Notably, Japan has faced energy crises before, most prominently after the 1973 Arab Oil Embargo and following the 2011 Fukushima nuclear disaster, which led to the shutdown of most of its nuclear capacity and a surge in fossil fuel imports. The current response mirrors the urgency of those earlier crises, but with a more geographically diversified strategy.

Energy analysts argue that while the 60 per cent figure provides short-term reassurance, the remaining 40 per cent of May's crude requirement still depends on Hormuz-routed supply, leaving Japan exposed if the conflict escalates further.

What to Watch Next

All eyes will be on whether Japan can raise its Hormuz-bypass procurement above 60 per cent for June and July 2025, and whether the POWERR Asia framework delivers stable supply volumes from October 2025 as promised. Any further escalation in the Middle East, particularly involving Iran, which borders the Strait of Hormuz, could force Tokyo into emergency procurement at premium global prices, adding inflationary pressure to an economy already navigating a weak yen.
