Saudi Arabia Secures Nearly Half of Japan's Oil Imports as Regional Disruptions Reshape Energy Markets

Japan's energy landscape has shifted dramatically amid geopolitical tensions in the Middle East, with Saudi Arabia now commanding a commanding position in the country's crude oil supply chain.

Data released by Japan's Ministry of Economy, Trade and Industry through its Natural Resources and Energy Agency reveals that Saudi crude accounted for 44.8 percent of Tokyo's total oil imports during April 2026. The kingdom delivered approximately 11.47 million barrels—equivalent to 1.82 million kiloliters—during the month.

The dominance of Saudi supplies reflects broader disruptions affecting regional energy flows. The actual closure of the Strait of Hormuz and military operations across the region have triggered a noticeable contraction in supplies from neighboring producers.

Four Arab nations have become the backbone of Japan's oil security. Saudi Arabia, the United Arab Emirates, Oman, and Qatar collectively supplied 87.6 percent of Tokyo's petroleum requirements in April. The UAE ranked second with a 40.5 percent share, delivering approximately 10.39 million barrels. Oman followed with 1.8 percent of imports, while Qatar contributed 0.5 percent. Kuwait's absence from the data proved noteworthy—the ministry recorded zero imports from the country during the period.

Japan's overall crude imports fell to their lowest monthly level since 1962, a consequence of regional instability stemming from the Iran War. To navigate this constraint, Tokyo has diversified its procurement strategy beyond traditional Middle Eastern sources. The United States now supplies 7.7 percent of Japanese imports, while Ecuador and Brunei account for 2.3 percent and 1.2 percent respectively. Simultaneously, Japan has drawn heavily from its national strategic petroleum reserves to sustain domestic energy needs.
