In a significant move, Japan has approved the restart of the Kashiwazaki-Kariwa nuclear power plant in Niigata Prefecture, the world’s largest nuclear facility. This decision, finalized on December 22, 2025, marks a pivotal moment in Japan’s energy policy, signaling a return to nuclear energy nearly 15 years after the Fukushima disaster.

The Kashiwazaki-Kariwa plant, located about 136 miles northwest of Tokyo, was among the 54 reactors shut down after the devastating earthquake and tsunami that led to the Fukushima Daiichi nuclear disaster in 2011. The approval for the restart comes after years of rigorous safety assessments and local political backing, as Tokyo Electric Power Company (TEPCO) seeks to ensure a stable electricity supply and reduce its reliance on imported fuel.
While supporters of the restart argue that nuclear energy is crucial for Japan’s energy security and climate goals, critics, including local residents and environmental activists, have raised concerns about the safety risks associated with nuclear power. The Fukushima disaster, which resulted in widespread radioactive contamination and forced thousands of people to evacuate, continues to cast a shadow over Japan’s nuclear energy industry.
The decision to restart the Kashiwazaki-Kariwa plant has sparked controversy and reignited debates about the role of nuclear power in Japan’s energy mix. Proponents emphasize the importance of nuclear energy in reducing greenhouse gas emissions and ensuring energy security, while opponents highlight the potential risks of nuclear accidents and the long-term environmental consequences.
As Japan moves forward with the restart of the world’s largest nuclear plant, it faces the challenge of balancing the need for reliable energy sources with the imperative of ensuring safety and environmental protection. The outcome of this decision will have far-reaching implications for Japan’s energy future and its commitment to sustainable development.
