The average retail price of regular gasoline stood at ¥136.90 per liter as of Monday, down ¥0.60 from a week earlier and marking the fourth straight weekly decline, the Oil Information Center said Wednesday.
While wholesale prices remained flat amid steady crude oil prices, fierce competition at the pumps led to a fall in retail prices across the country, an official of the center said.
The average price of high-octane gasoline was down ¥0.70 at ¥147.60 and that for diesel oil was down ¥0.40 at ¥115.80, it said.
