The Sudden Fragility of the Hormuz Lifeline

For decades, Japan’s industrial economy relied on a narrow 33-kilometer strip of water for nearly its entire energy supply. This vulnerability reached a breaking point in late February 2026, when military strikes between the US, Israel, and Iran led to a blockade of the Strait of Hormuz. With 95.1% of its crude imports originating from the Middle East and three-quarters of that volume passing through the now-obstructed strait, Tokyo was forced to confront a total disruption of its primary energy artery. The blockade left over 150 tankers stranded, effectively halting the flow of 1.6 million barrels per day destined for Japanese ports.

Emergency Reserve Drawdowns and Strategic Shifts

In response to the crisis, the Japanese government announced its largest emergency reserve drawdown in nearly five decades on March 16. The release of 80 million barrels—approximately 45 days of consumption—was designed to buy the nation time but offered no long-term solution for replenishment. This clinical urgency has accelerated a pre-planned but quiet strategy to diversify supply routes away from the Persian Gulf. At the center of this movement is INPEX, which is now rewriting its global supply chains to prioritize the Japanese market over its traditional European spot-market customers.

Redirecting the Caspian’s Giant Fields

INPEX holds significant upstream stakes in two of the most productive assets in the Caspian region: the Azeri-Chirag-Guneshli (ACG) complex in Azerbaijan and the Kashagan field in Kazakhstan. According to reports from Yomiuri Shimbun and NHK, the company has officially decided to give domestic Japanese buyers priority for oil from these fields. This shift marks a historic reversal in energy flow, as these Caspian barrels—traditionally considered "European" oil—are now being eastern-bound to fill the vacuum left by the Hormuz blockade. While the volumes cannot fully replace Middle Eastern imports, they represent a critical pillar of Japan’s emergency procurement strategy.
