Japan has taken the extraordinary step of initiating the biggest-ever release from its oil reserves, with Prime Minister Sanae Takaichi confirming that some 80 million barrels will be made available to the country’s refiners starting Thursday. The scale of the release — equivalent to 45 days of domestic demand — underscores the severity of the energy threat posed by the ongoing conflict between the United States, Israel, and Iran. For a country that imports over 90% of its oil from the Middle East, this crisis cuts directly to the heart of national economic survival.
Japan’s energy vulnerability is a structural reality that successive governments have spent decades trying to manage through diversification, conservation, and strategic stockpiling. The country’s reserves, which stood at roughly 470 million barrels at the end of last year, represent a substantial insurance policy against exactly the kind of supply shock now unfolding. The government’s readiness to deploy this buffer decisively reflects a mature crisis management approach honed through years of experience.
The current release is 1.8 times larger than the one triggered by the 2011 Fukushima nuclear catastrophe, which until now had stood as Japan’s single largest emergency oil deployment. That crisis forced the closure of all of Japan’s atomic plants, creating a sudden and severe energy gap that took years to fully bridge. The scale of the present response suggests the government regards the current situation as at least as serious.
Fuel price subsidies have been introduced in parallel, capping gasoline at around ¥170 per litre after the retail price climbed to a record ¥190.8. The subsidy structure will be reviewed each week to ensure it remains calibrated to real market conditions. Japan’s trade and industry ministry is clearly focused on ensuring the burden of the global energy crunch does not fall disproportionately on households and small businesses.
Japan’s diplomatic track remains active, with Takaichi engaged in close coordination with regional and international partners to press for a peaceful resolution to the Middle East conflict. Her refusal to send naval forces to the Strait of Hormuz — based on Japan’s pacifist constitution — has drawn attention globally but reflects a consistent and principled foreign policy stance. Japan’s influence in the region will be exercised through economic diplomacy rather than military power.
