"Japan may not need LNG for 20 years ... but other Asian countries need to replace coal with something and LNG will play an important role," he said, adding that JERA could supply fuel to those countries likely to need it.
"We don't view LNG demand just for Japan, but for Asia as well," he said.
Last December, JERA signed a key deal with Oman LNG to buy up to 12 cargoes, or about 800,000 tonnes a year for a decade, beginning from 2025.
Asian spot LNG prices held at 22-month lows in April as demand stayed weak in the key north Asian markets of China, Japan and South Korea.
Apart from its integrated gas-to-power business, which covers fossil fuel procurement through power generation, JERA is expanding use of renewable power to decarbonise.
