Nuclear regulators did not pay sufficient attention to improvements in nuclear safety standards as recommended by the International Atomic Energy Agency (IAEA) and the Japanese Nuclear Industrial and Safety Agency had been promoting nuclear energy without being open about the inherent risks. According to the report, the Nuclear and Industrial Safety Agency strongly opposed a plan in 2006 to enhance preparedness against a nuclear disaster, fearing such a move would raise concerns about the safety of nuclear power among residents living near atomic plants. The failure of the central and local governments to consider the possibility of a nuclear accident caused by multiple factors such as earthquakes and tsunami also caused a delay in responding to the accident. According to the report there was an insufficient crisis management structure for ensuring the safety of local communities. The Japanese government failed to give a detailed announcement about what was happening and how it might affect people living nearby, while the Nuclear and Industrial Safety Agency was reluctant to inform the media that reactor 1's fuel rods possibly melted, although it knew that was quite likely.
