What You'll Learn
Japan's fossil fuel imports
Japan depends heavily on imported fossil fuels to meet its energy demands. In 2022, the country relied on imports for most of its fossil fuel supply, with close to 100% of its crude oil and coal supply being imported. Japan is the world's largest importer of liquefied natural gas (LNG), with an import dependency rate of approximately 97.8% in 2022. The country also has one of the largest LNG import volumes in the world.
Japan's LNG imports are more diversified, with a third originating from regional suppliers in Southeast Asia. However, Middle Eastern countries like Qatar continue to be significant LNG suppliers, solidifying LNG's role as a cornerstone of Japan's energy policy. In 2013, Japan also began importing all of its coal, primarily sourced from Australia.
The country's heavy reliance on fossil fuel imports has led to concerns about energy security and vulnerability to changing international situations. Additionally, Japan's fossil fuel imports contribute significantly to global warming and air pollution, making the expansion of renewable energy sources crucial. While Japan has declared ambitious climate goals and aims to be carbon-neutral by 2050, there is skepticism about its ability to expand renewable energy sufficiently to achieve this target.

Oil, coal, and LNG usage
Japan relies heavily on fossil fuels such as oil, coal, and liquefied natural gas (LNG) to meet its energy demands. However, due to the scarcity of domestic energy resources, the country is largely dependent on imported fossil fuels. In recent years, Japan has been working to reduce its reliance on fossil fuels and transition to renewable and nuclear energy sources.
Oil has been a significant energy source for Japan, with consumption reaching around 5.1 million barrels per day in the late 1980s. However, domestic oil consumption declined slightly over time, and Japan has experienced oil crises, such as in the 1970s and the 2019 attack on a Japanese ship in the Strait of Hormuz, which highlighted the vulnerability of relying on imports. As a result, Japan has diversified its energy resources, and oil consumption decreased to 4.9 million barrels per day in 1990.
Coal has also played a crucial role in Japan's energy mix, supplying half of the country's energy needs in 1950. However, the production volume of coal dropped sharply after 1990 due to the depletion of small deposits. As of 2022, coal still accounted for 31% of Japan's energy generation. Japan aims to phase out coal and reduce its share in electric generation to 19% by 2030 through plant retirements and the adoption of renewable energy sources.
LNG has become an important part of Japan's energy strategy, with the country pioneering Asia's LNG industry in the 1970s and 1980s. LNG consumption increased significantly following the 2011 Fukushima Daiichi nuclear accident, which led to the shutdown of nuclear reactors. However, since 2019, LNG consumption in the electric power sector has been declining as nuclear capacity has returned to service. Japan intends to secure long-term LNG contracts while also transitioning to renewable energy sources, recognizing LNG's role as a lower-emission alternative to coal.

Nuclear energy alternatives
Japan depends on fossil fuels such as oil, coal, and liquefied natural gas (LNG) for energy production. However, the country has been working to reduce its reliance on these fuels and increase the use of alternative energy sources. In 2022, about 4.6% of Japan's electricity was generated from biomass power, an increase from 4.1% in the previous year. Japan has also experienced a significant expansion of renewable energy capacity, with renewable energy sources accounting for close to 22% of electricity production.
Nuclear energy has been identified as a potential alternative to fossil fuels in Japan. In 2011, Japan shut down its nuclear reactors following the Fukushima nuclear accident, but the country has since restarted some of its nuclear plants. Nuclear energy is a reliable, large-scale energy source that can help reduce Japan's dependence on fossil fuels. Small Modular Reactors (SMRs) are a promising development in nuclear energy, offering improved safety, reduced costs, and increased flexibility compared to traditional nuclear plants.
Other alternatives to fossil fuels that Japan could consider include:
- Solar energy: Solar power is abundant and inexhaustible, and it can be harnessed through solar panels to convert sunlight into electricity. However, solar energy is dependent on the availability of sunlight and can be inconsistent due to weather variations.
- Wind power: Wind energy uses turbines to generate electricity from moving air. While wind power is renewable, it relies on consistent wind availability, which may not always be present.
- Geothermal energy: This form of energy taps into the Earth's internal heat, but it is limited to specific regions with volcanic or tectonic activity.
- Hydropower: Hydropower generates electricity from flowing water, but it requires large water reservoirs, making it geographically restricted.
- Thorium: Thorium is a silvery, slightly radioactive metal that can be used as a fuel in the nuclear cycle. It is more abundant than uranium and has been considered for nuclear power in Japan and other countries. Thorium-fuelled reactors are estimated to produce less waste and be more environmentally friendly than uranium-fuelled reactors.
- Natural gas: Natural gas can be used as an alternative to oil and has lower carbon emissions and other harmful pollutants. It is also cheaper than gasoline.
- Hydrogen: Hydrogen can be used in conjunction with a fuel cell to provide transportation and a source of power.
While Japan has made progress in adopting alternative energy sources, the country still faces challenges in reducing its reliance on fossil fuels. The energy sector in Japan is heavily influenced by imported fuel oil prices, and the country's electricity rates are impacted by the cost of renewable energy. Japan has set ambitious goals to cut emissions and achieve carbon neutrality by 2050, and a combination of these alternative energy sources can help the country transition away from fossil fuels.

Energy security concerns
Japan is highly dependent on imported fossil fuels, with over 99% of its crude oil supply and nearly 98% of its natural gas supply covered by imports, mostly from Middle Eastern countries. This heavy reliance on fossil fuel imports makes Japan vulnerable to geopolitical turbulence and the effects of climate change, impacting its national security strategies.
In response to the oil crises of the 1970s, Japan built strong economic and political ties with Middle Eastern producers to secure energy sources. While this ensured a stable supply of crude oil, it linked Japan's diplomatic priorities to its energy security requirements, forcing the country to prioritize relationships with these energy-producing nations.
Japan's energy security concerns have been further exacerbated by recent events, such as Russia's invasion of Ukraine, which led to complications with one of its few major suppliers outside the Middle East. The Biden administration's pause on new liquefied natural gas (LNG) export projects also caused concerns in Japan about potential restrictions on future gas supplies. These events highlight the vulnerability of Japan's energy supply to changing international situations.
To address these energy security concerns, Japan has taken several measures. Firstly, the country has diversified its LNG suppliers, recognizing the importance of Middle Eastern energy resources while also exploring other sources. Secondly, Japan has played a pivotal role in supporting new LNG projects in countries like Brunei, Malaysia, Australia, Indonesia, and Qatar, with state support being crucial in unlocking private capital for these ventures. Additionally, Japan has invested in renewable energy sources, aiming to reduce greenhouse gas emissions and decrease its dependence on fossil fuels. The country has experienced a significant expansion of renewable energy capacity, with a growing focus on battery energy storage systems.
However, Japan's transition to renewable energy and nuclear power faces challenges. Nuclear energy remains controversial after the Fukushima disaster, and there are concerns about the country's ability to expand its renewable energy share sufficiently to achieve carbon neutrality by 2050. Nevertheless, Japan's latest national security documents reflect a shift in Tokyo's understanding of its security context, presenting an opportunity to accelerate action on geopolitical and climate challenges.

Environmental impact
Japan is a major consumer of energy, ranking fifth in the world by primary energy use. Fossil fuels, including oil, coal, and liquefied natural gas (LNG), represent important sources of energy production in Japan. However, the country's heavy reliance on these fuels has significant environmental implications.
Firstly, the burning of fossil fuels is the main contributor to global warming and air pollution. Japan has been one of the largest carbon dioxide emitters worldwide, with the majority of its primary energy supply covered by fossil fuels. In 2019, fossil fuels accounted for 88% of the country's primary energy, and in 2022, the share of fossil fuels in the energy mix was over 72%. This has led to an increase in greenhouse gas emissions, which contribute to global warming and climate change. Japan's decarbonization efforts have been challenging due to this high dependence on fossil fuels.
Secondly, the country's overdependence on imported fossil fuels has led to a trade deficit and economic issues. In 2022, Japan's trade deficit hit a record high, largely due to its continued reliance on energy imports. The country imports most of its fossil fuels, with 97% of its oil and close to 98% of its natural gas being imported. This heavy reliance on imports makes Japan vulnerable to external supply shocks and international situations, impacting its energy security.
Additionally, the use of fossil fuels has environmental and health impacts. The burning of fossil fuels releases pollutants that contribute to air pollution and respiratory issues. The accumulation of carbon dioxide emissions leads to far-reaching environmental effects, including flooding, violent storms, melting glaciers, droughts, and rising sea levels. These environmental changes pose significant challenges to stability, natural life, and economic development.
To address these environmental concerns, Japan has set goals to reduce emissions and increase the use of renewable energy sources. The country aims to achieve net-zero emissions by 2050 and has committed to reducing greenhouse gas emissions by 46% from 2013 levels by 2030. Japan is also working to reduce its reliance on coal and increase the use of renewable energy sources such as biomass power, tidal power, and wave power. In 2022, the share of electricity generated from biomass power rose to 4.6%, and the country's renewable energy capacity has expanded by over 30% in the past five years.
