The Fukushima Daiichi nuclear disaster prompted a significant shift in Japan's energy policy, moving away from nuclear power for safety concerns. However, over the past 15 years, the momentum for abandoning nuclear energy has diminished, creating a renewed push towards nuclear power as the increase in electricity demand, fueled by advancements like artificial intelligence, becomes evident. This shift is marked by the endorsement of early nuclear reactor restarts and new constructions by many political parties in the recent House of Representatives election, indicating a potential shift in the political landscape surrounding energy policy.

A noteworthy point in this evolving narrative is the response of the Constitutional Democratic Party, which has its roots in the Democratic Party that was in power during the earthquake and tsunamis of 2011. Despite the historical stance of parties advocating for a nuclear-free future, this party did not include the commitment to "zero nuclear power" in its basic policies while forming a coalition with Komeito and the Centrist Reform Alliance. This represents a significant departure from previous post-disaster commitments and reflects the changing attitudes towards nuclear energy in Japan’s political landscape.

The implications of this renewed focus on nuclear power are critical. As the demand for electricity continues to rise, Japan is grappling with an energy policy that balances safety, economic growth, and environmental concerns. The conversation around nuclear energy is once again at the forefront, suggesting that Japan's long-term energy strategy will likely involve a complex integration of old and new technologies while addressing the legacy of the Fukushima disaster constructively.
