Fuel prices in Japan

Fuel Prices in Japan: What Drives the Cost at the Pump

As of the latest data, gasoline in Japan costs about $1.05 per liter (roughly ¥169.8 per liter), which works out to around $3.97 per US gallon. Diesel is cheaper at about $0.984 per liter. By global standards Japan sits comfortably below average: the world mean is roughly $1.484 per liter, and Japan ranks 34th out of 170 countries surveyed, meaning fuel here is more affordable than in most developed economies despite the country importing nearly all of its oil.

Why Japan Imports Almost All Its Fuel

Japan is one of the world's largest net energy importers. It has virtually no domestic crude oil or natural gas of its own, so essentially every liter of gasoline burned in the country begins as imported crude — much of it from the Middle East. That import dependence would normally push prices high, the way it does in other resource-poor importers. Compare this with an oil-rich exporter like the UAE, where pump prices are structurally lower because the crude is produced at home, or with mountainous Bhutan, which imports every drop overland from India.

So why isn't Japanese fuel more expensive? The answer is a combination of a relatively strong refining sector, efficient logistics, and — importantly — government intervention that has kept the retail price from tracking the full weight of import costs and taxes.

Taxes and Subsidies

A large slice of what Japanese drivers pay is tax. The gasoline tax (the kihatsuyu zei) plus a long-standing "provisional" surcharge and consumption tax together account for a substantial share of the pump price. This is why Japan's fuel is taxed heavily yet still ends up mid-tier globally — the underlying pre-tax product is competitive.

Since 2022, the government has run a large subsidy program paying wholesalers to cap retail prices, originally aimed at keeping gasoline below a target threshold during the global energy spike and a weak yen. Those subsidies have been a major reason Japan avoided the steep price shocks seen elsewhere, though policymakers have repeatedly debated winding them down.

The Yen Factor

Because crude is priced in US dollars, the yen's exchange rate matters enormously. When the yen weakens against the dollar, each barrel costs more yen even if the global oil price is flat. The yen's significant depreciation in recent years pushed import costs up sharply — and the subsidy program was, in part, a buffer against exactly that currency-driven inflation. For Japanese consumers, a weak yen is felt directly every time they refuel.

The Price Trend

Over the roughly ten years of data from July 2016 to June 2026, gasoline in Japan averaged about $0.949 per liter. The cheapest point came on 15 August 2016 at just $0.727 per liter, during a period of low global oil prices and a stronger yen. The peak arrived much more recently — $1.153 per liter on 21 April 2025 — reflecting the combined squeeze of elevated crude, a depreciated yen, and the tapering of subsidy support. Today's $1.05 sits above the decade average but below that 2025 high, suggesting prices have eased somewhat from their peak while remaining structurally higher than the mid-2010s.
