Japan’s new Prime Minister Sanae Takaichi, the country’s first female leader, took office this week amid rising inflation and energy import costs. Following the 2011 Fukushima disaster, Japan drastically reduced its reliance on nuclear power, forcing it to depend on expensive fossil fuel imports. With global energy prices soaring and domestic industries under strain, Takaichi is reviving the debate on how to secure stable, affordable, and decarbonized energy at home.
Why It Matters
Japan’s energy transition is critical not just for economic stability, but also for climate goals and industrial competitiveness. Reintroducing nuclear power and investing in perovskite solar cells a next-generation technology pioneered in Japan reflects a push to cut import dependency and stabilize electricity costs. The policy also positions Japan as a potential leader in clean-energy innovation while addressing the power demand surge driven by data centers and digital infrastructure.
The nuclear industry welcomed Takaichi’s stance, viewing it as a long-awaited green light for reactor restarts and new projects. Business leaders and manufacturing groups support the shift, citing lower costs in nuclear-heavy regions like Kansai and Kyushu compared to non-nuclear areas such as Hokkaido.
However, environmental groups and anti-nuclear activists remain wary, warning that prioritizing nuclear energy risks repeating past safety oversights.
What’s Next
Takaichi’s government plans to restart idle reactors, extend their operating lifespans to 60 years, and explore fusion energy development. Four more reactors have restart permits, and up to 10 others could apply soon. The administration aims to raise nuclear’s share of Japan’s power mix to 20% by 2040, while accelerating perovskite solar deployment as part of a broader decarbonization strategy.
