Fuel costs in Japan have moved again, with the latest figures from August 1, 2026 showing diesel at 151 yen per liter and petrol at 166 yen per liter. For international readers, that translates to roughly €0.83 and $0.96 for diesel, and €0.91 and $1.05 for petrol. The data, released by OpenVan.camp, offers a snapshot of what drivers and businesses can expect at the pump this month.

Diesel Price Breakdown

Diesel now averages 151 JPY per liter across Japan. In euro and dollar terms, this is about €0.83 and $0.96 respectively. For a typical 50-liter tank, filling up with diesel would cost approximately 7,550 yen, which is roughly $72 or €62.

The price reflects ongoing global crude oil trends and domestic tax policies. Japanese diesel prices have seen modest fluctuations over the past year, and this latest figure keeps the cost within a range that many commercial transport operators consider manageable.

Petrol Price Analysis

Petrol (regular gasoline) is priced at 166 JPY per liter, equivalent to €0.91 or $1.05. A full 50-liter tank of petrol would set drivers back about 8,300 yen, or around $87 and €75.

Petrol prices in Japan are often influenced by seasonal demand and refinery maintenance schedules. The August figure suggests a slight upward pressure compared to recent months, which could be attributed to summer travel peaks and higher import costs.

Regional Variations and Context

While these are national averages, fuel prices in Japan can vary significantly by region. Urban areas like Tokyo and Osaka typically see higher prices due to distribution costs, while rural prefectures may offer slightly cheaper options.

  • Petrol: 166 JPY/L (€0.91 / $1.05)

For context, these prices are in line with the broader Asian market, though they remain higher than in some neighboring countries. The Japanese government has historically used subsidies to soften price spikes, but such measures are not always in effect.

What This Means for Consumers and Businesses

For everyday drivers, the current petrol price means a modest increase in monthly fuel budgets. Businesses that rely on diesel, such as logistics and agriculture, will need to factor in these costs when planning their operations.

Analysts suggest that if global oil prices remain stable, Japanese fuel prices could stay near these levels through the coming weeks. However, any geopolitical disruption or major supply change could quickly alter the outlook.
