Inpex Corp signed a 15-year liquefied natural gas supply contract with Abu Dhabi National Oil Co to deliver gas from ADNOC’s Persian Gulf project.

The agreement gives Japan a reliable source of LNG, easing the country’s exposure to volatile global markets and helping meet growing domestic demand. Inpex’s long‑term commitment aligns with Japan’s strategy to diversify energy imports and secure supply stability.

For ADNOC, the contract locks in a steady buyer, strengthening its export profile and providing predictable revenue that can support new development projects and reduce financing costs.

Investors see the deal as a hedge against supply disruptions and a clear signal that East Asian buyers will continue to prioritize long‑term LNG contracts. The agreement also illustrates ADNOC’s push to broaden its market reach beyond traditional partners.

Overall, the transaction could help smooth regional LNG pricing and reinforce both firms’ positions in a market increasingly focused on supply security and long‑term planning.
