Although there are many surveys which investigate nuclear disaster at Fukushima 1st, the evaluation of TEPCO's risk management against tsunamis is still confused. In this research, I attempt a re-evaluation of TEPCO's risk management by using a new framework which complements several points which are overlooked by existing researches. As the result of this re-evaluation, I show following three points. (1) Awareness of the dangers of tsunamis against nuclear power plant was low among common people. (2) However TEPCO had a lot of knowledge about it, by provision of information from experts of tsunami. (3) Although TEPCO had enough risk information, they did not take sufficient measures against tsunamis. Since tidal wave prediction methods include the uncertainty of their results, this company fell into dilemma between cost and safety. Finally, I suggest that lack of discussions about corporate responsibility for risks which have insufficient scientific basis tangles risk management evaluation.
