Japan's energy sources have undergone significant changes over the years. In 1950, coal supplied half of Japan's energy needs, while hydroelectricity accounted for one-third, and oil the rest.

By 2001, oil had become the primary energy source, making up 50.2% of Japan's total energy needs, with nuclear power and natural gas also seeing significant rises in use. Today, Japan relies heavily on imported fossil fuels to meet its energy demand.

Here's a breakdown of Japan's primary energy use over the years:

Japan's oil consumption has been on a decline in recent years. By 2017, it had dropped to 3.22 million barrels per day, a significant decrease from the over 5 million barrels per day it was for decades.

Japan was the fifth-largest oil consumer and fourth-largest crude oil importer in the world in 2019. The country's reliance on imported fossil fuels has been a major concern, with oil making up 50.2% of Japan's energy needs in 2001.

In 2022, Japan's crude oil imports rose to 2.5 million barrels per day, an increase from 2.3 million barrels per day in 2021. The Middle East remained the predominant source of oil imports, accounting for 93% of the total.

Japan has made significant strides in renewable energy, with a goal to increase the renewable share to 36-38% of power generation by 2030. This is a notable increase from the previous target of 22-24%.

The country's main renewable energy source is hydroelectricity, with an installed capacity of about 27 GW and a production of 69.2 TWh of electricity in 2009. Japan has 1,198 small hydropower plants with a total capacity of 3,225 MW.

Renewable energy generation capacity in Japan has increased significantly, from 20.9 GW in 2012 to 26.2 GW. The feed-in tariff scheme implemented by the Japanese government has encouraged companies to invest in renewable energy.

In 2022, renewables made up 22.7% of Japan's overall electricity generation, a slight rise from 22.4% in the previous year. Solar energy capacity has been growing steadily, reaching 87,068 MW by 2023.

Here is a breakdown of Japan's renewable energy capacity by type:

Geothermal energy has potential in Japan due to its proximity to the Izu-Bonin-Mariana Arc and volcanic activity. However, development has been slow due to concerns about impact on the landscape and tourism industry.

Japan's energy sector has experienced a significant expansion of renewable energy capacity, growing by over 30% in the past five years.

The country's demand for battery energy storage systems (BESS) has skyrocketed, with over half of the 2.4 gigawatts of capacity awarded in recent long-term low-carbon power auctions going to foreign companies or consortia.

A major project includes over 1.37 GW of new BESS capacity, and more than 6.7 GWh of energy capacity has been approved for 2024.

The Japanese government's Long Term Decarbonization Power Source Auction incentivizes BESS development by guaranteeing fixed cost recovery for 20 years.

However, limited price volatility and a price floor in the Japanese power market may constrain returns for BESS operators, highlighting the need for further reforms.

Japan's energy sector has undergone significant changes in recent years. The country's nuclear power program was strongly opposed by environmental groups in the 1980s, particularly after the Three Mile Island accident in the United States.

By 2011, nuclear power accounted for around 30% of Japan's total electricity production. However, the 2011 Tōhoku earthquake and tsunami damaged some nuclear reactors, leading to the Fukushima nuclear accident and a shutdown of the last nuclear reactor on 5 May 2012.

The Japanese government aims to increase the share of nuclear energy to 20% of the country's energy supply by 2040. To achieve this goal, 20 GW of nuclear capacity will need to be restarted, bringing all of Japan's 33 GW of installed nuclear capacity back into service.

The electricity sector in Japan has undergone significant changes in recent years. Japan's nuclear power program was heavily reliant on imported technology and uranium from various countries.

Following the Fukushima nuclear accident in 2011, Japan shut down its last nuclear reactor in May 2012, marking the first time there had been no nuclear power production since 1970. By 2018, some reactors had been restarted, including those at the Ōi and Genkai nuclear power plants.

Japan aims to increase its nuclear power share to 20% of its energy supply by 2040, up from 8.5% in 2023. To achieve this goal, 20 GW of nuclear capacity will need to be restarted.

Solar power has become a significant contributor to Japan's electricity mix. In 2012, new tariffs for renewable energy were introduced, and solar power producers were offered ¥42 per kWh over 20 years. This led to a surge in solar capacity, with 1,718 MW added in 2012 alone.

By 2022, solar photovoltaic (PV) systems generated 9.9% of Japan's total annual electricity output, a growth of 0.6 percentage points from the previous year. Solar energy capacity in Japan has continued to grow, reaching 87,068 MW by 2023.

Here's a breakdown of Japan's solar energy capacity from 2014 to 2023 (MW):

Japan has a unique national grid system, unlike most other industrial countries, with separate eastern and western grids operating at different frequencies.

The standard voltage at power outlets is 100 V, but the grids operate at 50 Hz in Eastern Japan and 60 Hz in Western Japan.

These two grids were originally developed by separate companies, with Tokyo Electric Light Co establishing the eastern grid in 1883 and General Electric supplying equipment to Osaka Electric Lamp for the western grid in 1885.

The grids are connected by three frequency converter stations, but they can only handle a total of 1 GW in power transfer.

A converter station also exists at Minami-Fukumitsu, but it's not clear what its capacity is.

The 2011 Tōhoku earthquake and tsunami resulted in a significant loss of power, with 11 reactors being taken offline and 9.7 GW of power lost.

Demand uncertainty is a major challenge for LNG suppliers, and Japan's energy plan is a prime example. Japan's electricity demand is expected to reach between 1,100 and 1,200 TWh in 2040, driven by growth in AI-led data centres and wider electrification.

This is a significant increase from 984 TWh in 2023, and it's not just a matter of growth, but also a shift in the generation mix. Thermal power will remain in the generation mix for longer, with coal and gas contributing as much as 40% by 2040, rising to 45% in the 'Slow Technological Progress' scenario.

Japan will be in the market to seal export deals for carbon storage, which has major implications for LNG suppliers. Wood Mackenzie's base case forecast for LNG demand in 2040 is 54 Mt, which is at the lower end of the range implied by the latest SEP.

However, based on the scenarios presented, there could be an additional demand upside of up to 20 Mt, which is a significant increase. This has major implications for LNG suppliers looking for buyers to underpin new projects, particularly given an increasing need for contract flexibility due to the uncertainty in domestic demand growth.
