Oil Price in Japan — Brent & WTI Crude Today

Japan is a major oil importer with virtually no domestic production. The country relies heavily on Middle Eastern crude priced against Brent, and oil price fluctuations have an outsized impact on its trade balance and energy costs.

Classified here as a net importer, Japan trades against the Dubai/Oman average and Brent. That is the pricing reference the sections below work from — the headline Brent number quoted at the top of this page is the global marker, not necessarily the price Japan settles at.

Japan produces no meaningful volume of crude, so every barrel consumed has to be bought at an internationally set price. That makes the Brent benchmark a direct input into the trade balance: a sustained move in crude shows up in the current account, in the currency, and eventually in domestic inflation.

Asian refiners buy most of their crude on Dubai/Oman-linked term contracts from Gulf producers, and top up with Brent-linked Atlantic Basin cargoes when the Brent–Dubai spread makes that arbitrage work.

Japan runs refining capacity at export scale. That changes the exposure profile completely: the country buys crude and sells products, so what matters is the refining margin — the crack spread between the crude it takes in and the gasoline, diesel and jet it ships out — rather than the crude price on its own. A high Brent price with wide cracks can be a better outcome here than cheap crude with collapsed margins.

Crude is invoiced in US dollars, so buyers in Japan face two prices at once: the Brent price and the JPY exchange rate. A weakening JPY raises the local cost of a barrel even when Brent is flat, which is why domestic fuel prices in currency-exposed markets often fail to fall when the benchmark does. The reference rate used in the estimates on this site is 152 JPY per USD.
