FY2018 Japan’s Independent Development Ratio of Oil and Natural Gas Released

July 29, 2019

Japan’s independent development ratio of oil and natural gas in FY2018 was 29.4%, up by 2.8% from the previous year.

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 entities, including domestic production, out of the total amount of imported and domestically-produced oil and natural gas.

As Japan is a country largely dependent on imports from abroad for its oil and natural gas, it is vitally important that it secure a diversity of supply channels. To this end, since the formulation of the Fifth Strategic Energy Plan approved by the Cabinet in July 2018, Japan has been supporting Japanese enterprises so as to improve the current independent development ratio in Japan for both oil and natural gas, including domestic production, to over 40% in 2030.

2. Factor analysis

The FY2018 independent development ratio of oil and natural gas in Japan showed an increase by 2.8% from the previous year. This increase is considered to be derived from the start of production under the LNG project in Australia, a production increase in multiple oil-gas fields and other factors, resulting in an increase in the offtake amount of oil and natural gas by Japanese enterprises.

Independent development ratios (%)
2009 1.241 23.1
2010 1.297 23.5
2011 1.296 22.6
2012 1.294 22.1

2016 1.533 27.4
2017 1.452 26.6
2018 1.531 29.4

Note: Offtake amount of natural gas is the crude oil equivalent.

Changes in Japan’s independent development ratios of oil and natural gas since FY1973

Note: From FY1973 to FY2008, the independent development ratios were calculated based on oil amounts alone. Since FY2009, ANRE has been calculating the ratios based on the combined amount of oil and natural gas and releasing the results.
