About the cause of Fukushima Daiich nuclear accident, the investigation reports were published by various accident investigation committees which are the government, the national diet, the private sector, TEPCO and academic societies. However, it is the current state that the difference of investigation results between the accident investigation reports and the difference of judgements between the specialists still remain.
