The United Arab Emirates was Japan’s largest source of crude oil in September 2026, supplying nearly half of the country’s total imports. Official figures show that the UAE delivered 28.2 million barrels, accounting for 48.5% of Japan’s crude oil purchases during the month.
Japan imported a total of 58.18 million barrels of crude oil in September, according to data released by the Ministry of Economy, Trade and Industry. The United States ranked second among suppliers, followed by Saudi Arabia.
The figures highlight the UAE’s important role in meeting Japan’s energy needs. They also show how global oil trade has changed amid continuing disruption around the Strait of Hormuz.
The United States supplied 15.98 million barrels of crude oil to Japan during September. This represented 27.5% of total imports. Saudi Arabia ranked third, delivering 8.37 million barrels, or 14.4% of Japan’s total supply.
The changing supply mix comes as the blockade of the Strait of Hormuz continues to affect energy shipments. Analysts say the disruption has created opportunities for American oil companies as buyers seek alternative sources of crude oil.
Japan has traditionally depended heavily on Middle Eastern suppliers. Before the current disruption, Arab countries reportedly provided around 95% of its crude oil imports. The latest figures show that the region remains important, although the share supplied by different countries has changed.
Arab nations collectively supplied 39.82 million barrels to Japan in September. This represented 68.4% of the country’s total crude oil imports. The UAE accounted for the largest share, followed by Saudi Arabia and other regional producers.
Oman supplied 1.84 million barrels, equal to 3.2% of Japan’s imports. Kuwait delivered another 1.39 million barrels, accounting for 2.4%.
The Japanese ministry reported no crude oil imports from Qatar, Iran or Russia during September. The absence of shipments from these countries reflects the changing pattern of Japan’s oil purchases during a period of uncertainty in global energy markets.
Japan also obtained smaller amounts of crude oil from suppliers outside the Middle East and the United States. Mexico accounted for 1.5% of imports, while Australia supplied 1%. Ecuador contributed 0.8%, and Argentina provided 0.6%. South Sudan accounted for 0.1% of total imports.
Although these countries supplied much smaller volumes, they show the range of sources available to Japanese buyers. Diversifying suppliers can help reduce the risks linked to relying too heavily on one region or transport route.
However, replacing large volumes of Middle Eastern crude oil is not simple. Japan needs steady supplies to support its industries, transport systems and power sector. Changes in shipping routes or access to major oil producers can affect delivery times and costs.
The Strait of Hormuz is a key route for global energy shipments. Disruption in the area can affect oil flows from several major producers and create uncertainty for importers. Countries that rely on overseas energy supplies may respond by seeking additional suppliers, adjusting purchases or using alternative transport arrangements where possible.
The United States has become a major supplier to Japan during this period. Its September share of 27.5% placed it behind only the UAE. This represents a significant part of Japan’s monthly crude oil supply and highlights the growing importance of American exports in the current market.
The UAE’s leading position also underlines its importance as a global energy producer. Its supply of 28.2 million barrels made it Japan’s largest crude oil source for the month. The relationship reflects the continued role of Gulf energy producers in supporting major Asian economies.
Japan remains highly dependent on imported energy. Crude oil accounts for about 25% of the country’s energy needs, making reliable access to supplies important for economic stability. Any prolonged disruption to oil shipments could increase costs for businesses and consumers.
The September figures provide a snapshot of Japan’s response to changing energy conditions. While Arab countries continued to provide more than two-thirds of its crude oil imports, the United States supplied more than a quarter.
The UAE’s position at the top of the supplier list shows that its role in Japan’s energy market remains substantial. At the same time, the growing share of American crude oil highlights how geopolitical tensions and shipping disruptions can reshape international trade.
Future import patterns will depend on supply availability, shipping conditions and the wider situation around the Strait of Hormuz. For Japan, maintaining reliable access to crude oil from multiple sources will remain a key priority as it works to protect its energy security.
