Prime Minister Sanae Takaichi has framed Japan’s biggest-ever oil reserve release as part of a broader commitment to peace and stability in the Middle East, announcing on Thursday the deployment of approximately 80 million barrels from national stockpiles to domestic refiners. Takaichi described peace in the region as “extremely important for Japan and the international community,” pledging that Tokyo would “make all necessary diplomatic efforts” in coordination with partner nations. The reserve release is the practical economic dimension of this diplomatic commitment.
Japan’s strategic petroleum reserves of approximately 470 million barrels — enough to cover 254 days of domestic consumption — represent a formidable national asset that the government is now deploying on an unprecedented scale. The 80 million barrels being released covers 45 days of national demand and exceeds the Fukushima-era release by 1.8 times. The depth of Japan’s reserves reflects the country’s consistent strategic investment in energy security over decades.
The economic rationale for the release is straightforward: Japan imports more than 90% of its crude oil from the Middle East, and the US-Israel conflict with Iran has disrupted the flow of tankers through the Strait of Hormuz. Any sustained reduction in oil deliveries would quickly translate into fuel shortages and price spikes affecting every sector of Japan’s economy. The reserve release is designed to bridge the gap while normal supply routes are restored.
Gasoline prices had already hit a record ¥190.8 per litre before the government introduced weekly-reviewed subsidies to cap costs at approximately ¥170. These measures have been welcomed by consumers and businesses alike, though officials acknowledge that much depends on how quickly the Middle East situation is resolved. The trade ministry continues to monitor supply chains for any signs of broader disruption beyond the fuel sector.
Internationally, Takaichi has held firm to Japan’s constitutional pacifism, declining Trump’s request for naval deployment to the Hormuz area while committing to sustained diplomatic engagement. Japan’s voice in Middle East affairs carries weight by virtue of its economic interests and longstanding regional relationships. The prime minister is betting that diplomatic persistence, backed by a stable domestic energy supply, will see Japan through this crisis.
