At the time Reuters suggested that the Onagawa nuclear power plant may demonstrate that it is possible for nuclear facilities to withstand the greatest natural disasters, and to retain public trust. The plant was shut down following the earthquake and tsunami, in accordance with standard legally mandated procedure after such an event, but despite the IAEA finding that the plant had survived the quake remarkably undamaged, the three units remain in cold shutdown. Whereas the mishaps at Fukushima I radically changed public opinion on safety and risks, Tohoku Electric seems to have preserved much of its pre-disaster goodwill in the area of Onagawa. While the tsunami was more than 13m high at both Fukushima I and the Onagawa power plant, the largest difference between them, apart from the reactor safety systems being designed some twenty years apart, was that the Fukushima I seawall was built to a height of just 5.7m, while the Onagawa power plant seawall was nearly high and thus successfully blocked the majority of the tsunami from causing severe flood damage. It was this tsunami at Fukushima I that has been determined to be solely responsible for precipitating the loss of cooling and ultimately the Fukushima disaster which had a much shorter sea wall of . In response to the high tsunami, Onagawa power plant's seawall was later built up to a height of .
