The Japanese government is considering an additional release of national oil reserves in May.

The Japanese government is considering releasing additional national oil reserves in May, with the release amount equivalent to about 20 days of Japan's oil consumption. According to data from the Ministry of Economy, Trade and Industry of Japan, as of the end of 2025, Japan's total domestic oil reserves are equivalent to 254 days of consumption. Due to disrupted passage through the Strait of Hormuz, since March 16 the Japanese government has released a total of approximately 80 million barrels of oil reserves, equivalent to 45 days of Japan’s oil supply. This is the largest release since Japan established its national oil reserve system in 1978. Expand
