Because Japan possesses extremely limited domestic natural resources, it relies heavily on massive international imports to fulfill its energy demands and stands as one of the world's largest importers of liquefied natural gas. Japan sources its natural gas supply from a diverse roster of global partner countries spread across Oceania, Southeast Asia, the Middle East, and North America. Historically and currently, Australia serves as Japan's premier and largest supplier of liquefied natural gas, providing a massive share of total imports. Additional significant volumes are purchased from countries such as Malaysia, the Russian Federation, the United States, Papua New Guinea, Qatar, Indonesia, Brunei, and Oman. This multi-source purchasing strategy ensures energy security and stabilizes national supply against localized geopolitical disruptions.
