Japan’s efforts to restart its nuclear reactors are gaining momentum as the country seeks reliable low-carbon baseload power, greater energy security and relief from rising electricity costs.
However, waste management, public opposition and lengthy licensing procedures could slow the process, according to GlobalData.
GlobalData’s latest report projects Japan’s nuclear power generation to rise from 101.0 TWh in 2025 to 123.3 TWh by 2035.
Nuclear capacity is expected to remain largely flat through 2029 before modest growth begins in 2030–31.
The company said existing reactors are undergoing safety upgrades and requalification, but unresolved nuclear waste storage issues, lengthy safety reviews and public concerns remain major barriers.
