As of today, the crude oil price in Japan is approximately ¥11,000–11,800 per barrel — Brent price (USD) multiplied by the live USD/JPY exchange rate. Japan's extreme Yen weakness since 2022 has dramatically increased crude import costs in Yen terms, even when Brent prices were moderate — making Japan one of the most affected developed economies by the double impact of high oil prices and a weak Yen.

Japan has zero domestic crude oil production and imports 100% of its crude oil needs — approximately 3 million barrels per day — making it the world's 3rd largest crude oil importer after China and India. Japan's top suppliers are Saudi Arabia, the UAE, Kuwait, and Qatar — all Gulf states pricing crude in USD against the Dubai/Oman benchmark. Japan's major oil refiners — ENEOS Holdings, Idemitsu Kosan, and Cosmo Energy — process imported crude at refineries in Kawasaki, Chiba, Yokohama, and Osaka.
Japan's Crude Oil Suppliers — 90% from the Middle East
Japan crude oil import sources — Saudi Arabia, UAE, Kuwait, and the strategic dependency on Middle East supply routes
Japan's extreme dependence on Middle Eastern crude — over 90% of imports come from Gulf states — makes it uniquely vulnerable to any disruption in the Persian Gulf or the Strait of Hormuz. The 1973 Arab oil embargo triggered Japan's first oil shock and directly reshaped its entire industrial and energy policy. Japan maintains 200+ days of strategic petroleum reserves — the world's largest relative to consumption — precisely because of this vulnerability.
Why Crude Oil Prices Change Daily in Japan
Why is crude oil price changing in Japan today — 4 key drivers for the world's most import-dependent major economy
Japan's crude oil price in Yen is devastatingly sensitive to the USD/JPY rate. When the Yen weakened from ¥115 to ¥155 in 2022–23, Japan's crude import costs in Yen rose by 35% on currency alone — even without Brent moving. Bank of Japan (BoJ) ultra-low interest rate policy (YCC — Yield Curve Control) has kept the Yen structurally weak, making oil imports chronically expensive.
Over 90% of Japan's crude passes through the Strait of Hormuz — the narrow chokepoint between Iran and Oman. Any military conflict, Iranian blockade threat, or Houthi attacks on tankers in the Red Sea immediately spikes Brent and Dubai crude prices. Japan maintains 200+ days of strategic reserves precisely to buffer this risk.
After the 2011 Fukushima disaster, Japan shut all 54 nuclear reactors — massively increasing crude oil and LNG imports to fill the power generation gap. Japan's crude oil demand surged 15–20% post-Fukushima. As Japan gradually restarts nuclear power plants, crude oil demand for power generation is declining — a structural bearish factor for Japanese crude imports.
Japan's rapidly aging and shrinking population is reducing long-term crude oil demand. Total vehicle ownership is declining, industrial output is shifting offshore, and energy efficiency has improved dramatically. Japan's crude oil consumption has been declining 2–3% per year since the 1990s — one of the world's most consistent structural demand reduction stories.
