Japan Faces Record Import Costs as Global Oil Prices Surge

Global crude prices, including Brent and WTI, have spiked more than 60% year-to-date, driving the massive increase in Japan's trade expenses. To secure its energy future, the country is actively diversifying its procurement strategy. Reliance on Middle Eastern suppliers—which once accounted for 95% of imports—is declining as Tokyo shifts toward the United States, Azerbaijan, South Sudan, and Russia. Imports from the Sakhalin projects remain critical, as these supplies avoid sanctions due to Japan’s specific energy dependence.

This shift in supply chains follows a dramatic reduction in traffic through the Strait of Hormuz, where shipping volumes remain 90% lower than pre-March 2026 levels. While the geographical pivot maintains supply security, it has triggered concerns regarding domestic inflation. Financial analysts expect the Bank of Japan to maintain its current interest rate policy this week, balancing the need to support the economy against the persistent pressure of rising energy costs as regional volatility in the Middle East continues to dampen hopes for a swift resolution.
