From Japan continues nuclear wastewater discharge while seeking permanent fuel storage

How could the national nuclear waste crisis affect Sanae Takaichi's policy agenda?

Likely What happens if… A possibility worth considering, not a forecast.

Takaichi's push for nuclear expansion intensifies Japan's spent fuel crisis Sanae Takaichi is actively pushing for the expansion of nuclear power in Japan to help meet huge electricity demands during a global oil crisis. However, this push directly contributes to the country's severe problem of spent nuclear fuel accumulation. Currently, cooling pools at 17 Japanese nuclear power plants hold over 17,000 tons of spent fuel, using nearly 80% of total storage capacity. The increased production from new or restarted reactors, driven by Takaichi's policy, accelerates the need for a permanent disposal solution, intensifying the debate over options like Minamitorishima.

The facts so far

As reported. Each one links to where it comes from.

  • Cooling pools at 17 Japanese nuclear power plants held more than 17,000 tons (15,422 metric tons) of spent fuel as of December 2025.wgcu.org, npr.org
  • Kashiwazaki-Kariwa is one of three plants whose cooling pools will be full in five years.wgcu.org, npr.org
  • Prime Minister Sanae Takaichi is pushing to bring more nuclear plants online.wgcu.org, npr.org
  • The government is considering Minamitorishima, a remote Pacific island south of Tokyo, for waste storage.wgcu.org, npr.org

Why it matters

The nuclear debate is central to Japan's energy security and long-term environmental planning. Takaichi's push for expansion is a direct response to the need to meet huge electricity demands during a global oil crisis, positioning her as a key driver of Japan's energy policy. However, this policy is fundamentally challenged by the lack of a permanent disposal solution for spent fuel, a problem that has persisted for decades since the 2011 Fukushima disaster.

This crisis forces the government to consider politically sensitive options, such as Minamitorishima, a remote island. The tension between the need for energy production and the inability to safely manage the resulting radioactive waste places significant pressure on Takaichi's administration, as the expansion accelerates the timeline for the waste management crisis.

What we don't know yet

  • Will the government successfully secure a final disposal site for spent fuel?
  • How will the public and local communities react to the proposed use of Minamitorishima?

What would change this answer

A viable permanent disposal plan is announcedThe pressure on Takaichi's expansion policy would ease, as the primary operational hurdle of waste storage would be addressed.
The cooling pools at Kashiwazaki-Kariwa fill sooner than five yearsThe urgency of the waste crisis would increase dramatically, potentially forcing a rapid shift in Takaichi's energy strategy.
