MISAWA AIR BASE, Japan — Diesel will cost more than $6 a gallon Saturday at U.S. military gas stations in Japan and South Korea as fuel prices continue to climb across the Pacific.
Army and Air Force Exchange Service stations in South Korea will raise diesel prices from $5.689 to $6.059 a gallon. Across Japan, diesel will increase from $5.659 to $6.029.
The increases come as global oil prices rise amid renewed fighting between the United States and Iran. Brent crude topped $100 a barrel Wednesday for the first time since July as Iranian missiles were fired into Jordan, The Wall Street Journal reported that day.
Premium gasoline is also getting more expensive.
Exchange customers in South Korea will pay $5.259 a gallon for premium, up 10 cents from $5.159. On Guam, premium will rise from $5.189 to $5.289, while customers across Japan will pay $5.229, up from $5.129.
Regular gasoline prices are increasing throughout the region as well.
In South Korea, regular will rise 9 cents, from $4.159 to $4.249 a gallon. On Guam, the price will increase 8 cents, from $4.189 to $4.269.
The increases vary more widely across Japan.
At Misawa Air Base in the northeast, regular will jump 27 cents, from $4.129 to $4.399 a gallon. On Okinawa, it will rise 23 cents, from $4.129 to $4.359 a gallon.
At Camp Zama outside Tokyo and Yokota Air Base in western Tokyo, it will increase 9 cents, from $4.129 to $4.219.
