Japan's oil and gas independence climbs to highest since 2009
Japan's self-sufficiency ratio for oil and natural gas rose to 42.1% in fiscal year 2024, which ended in March 2025, marking a 4.9% increase from the previous year, the industry ministry said on Tuesday.
The rise to the highest since 2009 is attributed to progress in energy development projects involving Japanese firms and a decline in oil and gas imports.
Self-sufficiency ratio measures the share of oil and gas from projects in which Japanese companies hold equity interests and domestic production against total imports and domestic output.
Fiscal year 2024 saw 1.789 MMbpd from these sources, compared to 1.241 MMbpd in 2009 when self-sufficiency was 23.1%.
Japan's energy policy aims to increase the self-sufficiency ratio to over 50% by fiscal year 2030 and beyond 60% by 2040.
The Seventh Basic Energy Plan, approved in February 2025, outlines these targets to secure stable energy supplies.
Japan's reliance on imports for most of its energy underscores the importance of the strategy.
