Japan is considering releasing an additional 20 days’ worth of oil from its strategic reserves as uncertainty persists over the reopening of the Strait of Hormuz, a key global energy route. The move, reported by Kyodo News, could take place as early as May if supply disruptions continue.

The country, which relies on the Middle East for around 95% of its oil imports, has already begun tapping into its reserves since mid-March in coordination with other nations. So far, Japan has made available roughly 50 days’ worth of oil consumption to stabilise domestic supply.

Despite a temporary ceasefire between the United States and Iran, the Strait of Hormuz — responsible for transporting nearly 20% of global oil — remains largely disrupted, raising concerns about continued supply shortages.

Japan still holds substantial reserves, estimated to cover about 230 days of consumption, but officials remain cautious due to ongoing geopolitical instability.

The government is also exploring alternative measures, including sourcing oil from non-Middle Eastern suppliers, subsidising fuel, and increasing coal-based power generation to manage the energy crisis.

The potential release highlights Japan’s vulnerability to global energy shocks and underscores broader concerns about supply security amid escalating regional tensions.
