Japan’s Nuclear Comeback: A Cautious Shift

Japan’s long-awaited move to restart one of the world’s largest nuclear power facilities is underway — but not without hiccups. Tokyo Electric Power Company (TEPCO) had planned to revive Reactor No. 6 at the Kashiwazaki-Kariwa Nuclear Power Plant, a 1.36 GW unit within a complex whose combined capacity is about 8.2 gigawatts, making it the largest nuclear facility globally. The restart, first scheduled for January 20, 2026, was momentarily delayed due to an alarm system malfunction during testing, but officials expect a new launch date soon after safety verification. The plan marks TEPCO’s first reactor revival since the 2011 Fukushima Daiichi meltdown, a turning point that led Japan to shut down most of its nuclear fleet amid public distrust and seismic safety concerns. 

The restart is symbolic of Japan’s broader energy recalibration: balancing a need to reduce reliance on imported fossil fuels with lingering fears from the Fukushima disaster. Local opinion remains divided, with safety worries and evacuation challenges especially pronounced in quake-prone regions. 

Kenya’s Nuclear Ambitions: Emerging Strategy and Local Debate

Kenya is simultaneously deepening its nuclear energy aspirations as part of its long-term energy strategy. State actors have outlined plans to build the country’s first commercial nuclear plant, with Kenya Electricity Generating Company (KenGen) designated to operate it and an initial facility expected to produce about 2,000 MW of power, scalable to larger capacities as the national grid expands. 

The government’s Nuclear Power and Energy Agency (NuPEA) has identified potential sites along the Indian Ocean coast — including Kilifi, Kwale, and Siaya counties — and continues stakeholder engagement and public education on safety, regulation, and community participation ahead of eventual construction. Kenya’s nuclear roadmap under its strategic plan anticipates commencing construction in 2027 and commissioning a first nuclear power plant by 2034, as part of efforts to diversify the energy mix and deliver more reliable, clean baseload electricity amid rising demand. 

Lessons and Implications for Energy Policy

Japan’s Experience

• Post-Fukushima caution: Nuclear restarts in Japan follow rigorous safety checks and regulatory scrutiny after the 2011 disaster, which forced a nationwide reevaluation of nuclear safety culture and emergency preparedness. 

• Public trust challenges: Local populations still express strong concerns about reactor safety and evacuation readiness, especially given seismic risk zones. 

• Energy security focus: Japan views nuclear as critical for reducing fossil fuel imports and stabilising power costs — a priority that resonates with many countries facing energy transitions. 

Relevance to Kenya

Kenya’s nuclear vision shares some drivers with Japan’s policy shift: a need for stable baseload electricity, support for industrial growth, and a cleaner energy mix amid climate concerns. However, Kenya’s context differs markedly:

• Institution building and regulation: Kenya is still developing its regulatory, technical, and human resource base for nuclear energy, guided by international standards and stakeholder engagement. 

• Infrastructure and financing: Establishing a nuclear programme involves heavy upfront investment and long lead times, with construction and commissioning potentially spanning into the mid-2030s. 

• Public engagement and safety assurance: Learning from countries with mature nuclear sectors could inform Kenya’s approach to community involvement, transparency, and emergency planning.

Conclusion

Japan’s cautious return to nuclear power — confronting both mechanical delays and community skepticism — highlights the technical and social complexities at the heart of nuclear energy. Kenya’s ambitions signal a strategic commitment to long-term energy diversification, but the pathway demands robust legal frameworks, regulatory independence, skilled human capital, and conscious public communication. In both nations, the nuclear debate underscores a fundamental reality: the tension between energy security and safety trust is as much political and societal as it is technical.
