Japan, the world’s third-largest economy, has unveiled a draft energy policy for fiscal year 2040 that seeks to strike a delicate balance between clean energy ambitions and energy security needs. Under this plan, renewable energy will account for 40%-50% of Japan’s power mix, while nuclear energy will constitute 20% of the total supply. This policy reflects Japan’s attempt to transition toward sustainability while addressing rising electricity demand and geopolitical risks.

Japan’s renewed focus on nuclear power and its cautious pace in phasing out coal-fired plants have drawn both domestic and international attention. Analysts note that the plan highlights energy pragmatism rather than an all-out shift toward renewables, positioning liquefied natural gas (LNG) as a vital transition fuel.

Energy Security Concerns Drive Policy Shift

Japan’s energy vulnerability stems from its heavy dependence on fossil fuel imports. As the world’s second-largest LNG importer and a significant consumer of Middle Eastern oil, Japan has faced heightened energy insecurity following geopolitical shocks like the Russia-Ukraine war and supply disruptions in the Middle East.

The revised draft reflects a shift in Japan’s priorities:

1. From Decarbonization to Energy Security: While clean energy remains central, the emphasis now includes securing stable, affordable energy sources.
2. LNG as a Transition Fuel: The government aims to hedge against supply disruptions by securing long-term LNG contracts. LNG will bridge the gap as renewables scale up and coal is phased down.

This pragmatism highlights lessons learned from the 2011 Fukushima disaster, which led to a sharp decline in nuclear power and an over-reliance on imported fossil fuels, exposing Japan to price volatility and energy insecurity.

Nuclear Power Makes a Comeback

The decision to retain nuclear power at 20% aligns with its 2030 goals but marks a significant shift in tone. The revised draft drops the earlier objective of “reducing reliance on nuclear power as much as possible,” signaling a renewed embrace of nuclear energy to meet base load demand—a stable supply of electricity critical for data centers and industrial use.

Nuclear power, though controversial due to safety concerns, offers a consistent energy supply. Japan plans to invest in next-generation reactors at sites where older reactors are being decommissioned. This strategy mirrors other nations’ nuclear revivals:

• France, a global nuclear leader, relies on nuclear power for nearly 70% of its energy mix and is expanding its nuclear fleet.
• South Korea, after years of uncertainty, is reinvesting in nuclear energy as part of its energy transition strategy.

For Japan, re-embracing nuclear power is a calculated move to stabilize its energy mix while pursuing decarbonization.

Renewables Progress, But Challenges Persist

Japan’s renewable energy targets—40%-50% by 2040—represent significant growth from 22.9% in 2023. However, the draft energy plan has drawn criticism for its conservative approach toward wind power, projected to account for just 4%-8% of the energy mix.

Critics argue that Japan risks falling behind global leaders:

• Germany aims to source 80% of its electricity from renewables by 2030, with a strong focus on wind and solar.
• China, the world’s largest renewable energy market, is on track to surpass its 2030 renewable targets ahead of schedule.

Experts like Mika Ohbayashi of the Renewable Energy Institute have called for a more ambitious push toward wind and solar to keep pace with global energy trends. Japan’s topography and grid infrastructure pose unique challenges, but investments in offshore wind farms and energy storage solutions could accelerate progress.

Rising Power Demand Adds Pressure

The draft energy plan assumes an electricity demand increase of 12%-22% by 2040, driven by growing sectors such as semiconductor manufacturing and data centers. This mirrors a global trend where rapid digitalization and industrial expansion have spiked power needs.

For instance, countries like India and China face similar challenges as they balance soaring power demand with clean energy goals. Japan’s approach, combining renewables, nuclear power, and transitional fuels like LNG, reflects a realistic path to addressing these pressures while aiming for net-zero emissions by 2050.

Lack of a Clear Roadmap for Coal Phase-Out

Despite its clean energy ambitions, Japan’s reluctance to set a clear coal phase-out timeline remains a major sticking point. Coal-fired power, though inefficient and environmentally harmful, continues to play a prominent role, supplying nearly 70% of Japan’s power in 2023.

Countries like the United Kingdom and Canada have taken decisive steps to phase out coal by 2030. Japan’s gradual approach risks undermining its credibility on climate commitments and global decarbonization efforts.

Pragmatic, Yet Controversial Path Forward

Japan’s revised energy policy signals a pragmatic balance between renewable ambitions, energy security, and nuclear revival. While its focus on nuclear power and LNG as transition fuels reflects realism, critics argue that its targets for wind energy and coal phase-out lack ambition.

To stay competitive globally and meet climate goals, Japan must accelerate investments in renewable energy infrastructure, improve energy storage capacity, and chart a clearer path away from coal. The upcoming finalization of the policy will determine whether Japan can achieve a sustainable, secure, and clean energy future by 2040.
