Summary	The situation in the Middle East deteriorated fur-ther following the attacks on Iran by the United States and Israel beginning in February 2026. The Strait of Hormuz was largely blockaded, threat-ening the stable supply of...
Outline	The blockade of the Strait of Hormuz has laid bare Japan's vulnerability. The country relies heavily on imports for its energy, with a self-sufficiency rate of just 16.3%. Estimates show that the rate for secondary energy stands at 0.2% for petroleum products and higher 30.7% for electricity. By sector, it is extremely low in transport and non-energy use, both of which are heavily reliant on oil. It, however, would be rash to pursue electrification as a risk mitigation measure. In addition to utilising oil reserves and securing alternative supply sources, it is essential to curb hoarding; depending on the circumstances, energy conservation may also be an important option. Whilst price subsidies are politically and socially beneficial, it is necessary to be mindful of their potential side effects.
