What's happened
Japan's Niigata Prefectural Assembly approved the partial restart of the Kashiwazaki-Kariwa nuclear plant, marking its first operation since Fukushima in 2011. The move aims to reduce reliance on fossil fuels amid energy security concerns, despite public protests and safety debates. The restart is scheduled for January 2026.
What's behind the headline?
The restart of Kashiwazaki-Kariwa signifies Japan's shift back toward nuclear energy after a decade of public opposition and safety concerns. The government and TEPCO are betting that safety measures and scientific assessments will reassure the public, but protests and trauma from Fukushima remain strong. This move will likely accelerate Japan's energy diversification, reducing dependence on imported fossil fuels, which cost the country billions annually. However, it also risks reigniting public distrust and safety debates, especially with the scheduled restart of additional units. The government’s push for nuclear revival aligns with its climate goals but faces ongoing social resistance. The decision underscores a complex balancing act between energy security, environmental commitments, and public safety.
What the papers say
The Japan Times reports that the Niigata Prefectural Assembly approved the restart, emphasizing safety and lessons learned from Fukushima. Al Jazeera highlights public protests and community division, with about 300 protesters opposing the restart despite official support. Reuters and AP News detail the political backing from Niigata's governor and the expected timeline for restarting units No. 6 and No. 7, with TEPCO considering decommissioning some units. The articles collectively illustrate the tension between energy policy and public sentiment, with government and utility officials emphasizing safety and economic benefits, while activists and residents express ongoing concerns about nuclear risks.
How we got here
Following the 2011 Fukushima disaster, Japan shut down 54 reactors and restarted only 14 of the remaining 33 operable units. The government and utilities have prioritized safety and energy security, with recent moves to restart reactors like Kashiwazaki-Kariwa, which has a capacity of 8.2 GW. The decision reflects Japan's broader strategy to cut fossil fuel imports and address climate commitments.
