FY2021 Independent Development Ratio of Oil and Natural Gas in Japan Released

1. Independent development ratio

Japan's independent development ratio of oil and natural gas is defined as the share of the offtake amount of oil and natural gas under the control of Japanese enterprises (including domestic production) out of the total amount of imported and domestically-produced oil and natural gas.

As this country is largely dependent on imports from abroad for its oil and natural gas, it is vital that it secures a diversity of supply channels. To this end, since the formulation of the Sixth Strategic Energy Plan (a Cabinet Decision was made in October 2021), Japan has been supporting its enterprises to improve the current independent development ratio in the country for both oil and natural gas (including domestic production) to over 50% in 2030 and 60% in 2040.

2. Factor analysis

The FY2021 independent development ratio of oil and natural gas in Japan showed a decrease by 0.5% from the previous year. This is likely because the oil and natural gas offtake amounts of Japanese enterprises have stayed almost exactly the same despite crude oil imports increasing as demand for it has recovered from COVID-19.
