Japan continues nuclear wastewater discharge while seeking permanent fuel storage
The latest in this situation
How it started
What happened
Tokyo Electric Power Company Holdings began the 21st discharge of nuclear-contaminated wastewater from the Fukushima Daiichi Nuclear Power Plant into the ocean on July 6, 2026, according to a report. This latest release is scheduled to contain about 7,800 tonnes of wastewater with approximately 1.3 trillion becquerels of radioactive tritium. Separately, Japan is seeking a permanent disposal site for spent nuclear fuel, and the government is considering Minamitorishima for this purpose.

Why it matters
The lack of viable plans for permanent spent fuel disposal threatens Japan's ability to sustain nuclear power generation, even as plants like Kashiwazaki-Kariwa restart to meet electricity demands. This situation is central to the policy advocated by Sanae Takaichi regarding TEPCO's nuclear capacity.
