A relief update for 4 November 2026 in Japan: the headline petrol and diesel lines eased versus the last stored day.
Drivers will see petrol at ¥170.10 after a reduction of ¥0.10 from ¥170.20.
Diesel is listed at ¥159.70 per litre on the same effective date.
Long-distance drivers may want to note the date stamp before a highway run. Filling just before or after a revision can land you on different sides of the same move.
City pump stickers can still differ slightly after local freight and dealer margins. Treat the headline litre price as the national or average reference, then glance at your usual station.
A cut is welcome, but it does not erase earlier hikes in the same month. Look at the week's path on the chart before calling the trend finished.
If you are comparing cars on running cost, pair this update with your typical monthly kilometres. A few coins per litre compounds across a commute month.
Before you fill up, decide whether you are topping a quarter tank or taking a full load. On a rising day, a smaller top-up limits how much of the new rate you lock in; on a falling day, a fuller tank captures more of the relief.
Local pump prices can still differ by city and station even when the headline rate is clear. Use the published litre rate as your reference, then trust the board in front of you for the final fill amount.
You can confirm today's petrol and diesel figures, plus the recent trend chart, on the Japan fuel prices tool. The article and the tool share the same dated history for 4 November.
Enjoy the softer board while it lasts, and still plan the next fill around the midnight window. Relief days can be brief under daily pricing.
