As the fifteenth anniversary of the Fukushima Daiichi Nuclear Power Plant accident approaches, Shinsuke Yamanaka, Chairman of the Nuclear Regulation Authority (NRA), emphasized the necessity of uncovering the truth regarding the disaster. In a media interview, he stated that failing to clarify the accident's true circumstances amounts to a betrayal of the international community. The NRA has been conducting investigations since its establishment in 2012, focusing on the events and causes of the catastrophe. A team of personnel continues to analyze data acquired from the highly radioactive reactor buildings, striving to elucidate the reasons behind unexpected occurrences, such as the discovery in 2022 that the concrete supporting the reactor had disappeared.

Yamanaka remarked on the significance of the ongoing investigations, highlighting that the development of new analytical models is underway to address these unforeseen scenarios. His assertion is that Japan's failures in managing nuclear safety must be transformed into shared human knowledge, aiming to share analytical results publicly soon. Furthermore, he asserted that without firsthand investigation data, it is impossible to truly understand the events or ensure genuine safety, signaling a commitment to incorporating specific findings into regulatory practices.

As decommissioning efforts continue at Fukushima Daiichi, Yamanaka conveyed his responsibility to fully restore the site to its original state and return it to the local population. Both the government and Tokyo Electric Power Company (TEPCO) aim to complete the decommissioning process by 2051, though Yamanaka expressed skepticism regarding the feasibility of this goal, asserting that discussions must occur soon regarding what can realistically be achieved by that deadline.
