Japan's Kashiwazaki-Kariwa Nuclear Power Plant Restart Suspended After Alarm Malfunction

Restart and Immediate Shutdown of Reactor No. 6
On January 21, 2026, Tokyo Electric Power Company (TEPCO) restarted Reactor No. 6 at the Kashiwazaki-Kariwa nuclear power plant, located in Niigata Prefecture, Japan. This marked the first operational activity at the facility since it was shut down following the Fukushima disaster in 2011. However, just hours after the restart, an alarm was triggered during control rod withdrawal operations, leading to an immediate suspension of the reactor's operations on January 22. TEPCO confirmed that no abnormal levels of radioactivity were detected, and the reactor remained stable throughout the incident.
Background and Context
The Kashiwazaki-Kariwa plant is the world's largest nuclear power facility by output, with a total capacity of approximately 8,965 megawatts across its seven reactors. All reactors were taken offline after the Fukushima disaster, which resulted from a 9.0 magnitude earthquake and subsequent tsunami, leading to significant public distrust in nuclear energy. TEPCO, which also operates the Fukushima Daiichi plant, has faced ongoing scrutiny regarding its safety practices and management.
Public Sentiment and Safety Concerns
Public opinion in Niigata remains sharply divided regarding the restart of the Kashiwazaki-Kariwa plant. A survey indicated that approximately 60% of local residents opposed the reactor's restart, citing safety concerns, particularly given the plant's location on an active seismic fault line. Protests have occurred, with demonstrators expressing fears about the potential risks of nuclear energy, especially in light of TEPCO's troubled history. Critics argue that the electricity generated primarily benefits Tokyo, while local residents bear the risks associated with nuclear operations.
Official Statements and Responses
TEPCO spokesperson Takashi Kobayashi stated, “The reactor is stable and there is no radioactive impact outside,” emphasizing the company's commitment to safety. However, he acknowledged that the investigation into the alarm malfunction would take time, indicating, “I don’t think this is going to be resolved in a couple of days.” TEPCO has committed to a thorough examination of the equipment involved in the incident before any further attempts to restart the reactor.
Criticism and Opposition
Opposition to the restart has been vocal, with groups submitting petitions signed by nearly 40,000 residents to TEPCO and Japan's Nuclear Regulation Authority. Protesters argue that the risks associated with the plant's operation, particularly in light of its seismic vulnerabilities, outweigh the benefits of nuclear energy. Local resident Yumiko Abe articulated the sentiment of many, stating, “It’s Tokyo’s electricity that is produced in Kashiwazaki, so why should the people here be put at risk?”
What's Next
TEPCO plans to conduct a comprehensive investigation into the alarm malfunction before resuming operations. The timeline for the reactor's return to service remains uncertain, with TEPCO officials indicating that safety must be prioritized. Meanwhile, the seventh reactor at Kashiwazaki-Kariwa is not expected to restart until 2030, and discussions regarding the future of the remaining reactors continue amid ongoing public concern and regulatory scrutiny.
