Japan's Agency for Natural Resources and Energy surveys the pump price of petrol at filling stations across the country every week. This map colours each prefecture by the survey's average price of regular petrol (cash, including tax, per litre) and shows the change from last week, the gap with the national average and the trend over the past year. These are prefecture averages, not the price at any one station.
The map colours show the average price of regular petrol (cash, including tax, per litre) in each prefecture. It is a prefecture average, not the price at any one station.
Switch to "Vs national average" or "Vs last week" to colour each prefecture by whether it is above or below the national average, or by how much it rose or fell from the previous survey.
Switch to "By week" and use the slider to see any week of the past year.
Tap a prefecture to see high-octane, diesel and kerosene prices and the trend over the past year.
No. It is the average of the prices the Agency for Natural Resources and Energy collected at stations in the prefecture. Each station's price is different.
Not on a fixed schedule: when the Agency for Natural Resources and Energy publishes new results of its survey (usually on Wednesdays at about 2 p.m. Japan time).
