Gasoline prices rose about 20 percent, prompting the government to introduce a fuel-price mitigation program. Despite these measures, the country likely cannot diversify substantially away from the Middle East.

Why it matters: This highlights the theme of energy security, as Japan's reliance on Middle East oil leaves it vulnerable to disruptions in the Strait of Hormuz.
