Tokyo Electric Power Co. on June 20 released its final report on the disaster at its Fukushima No. 1 nuclear power plant. Tepco stated that the main cause of the accidents was the enormous scale of the tsunami that hit the plant, saying that it was beyond its expectations.

The report basically stated that, looking back, Tepco was not careful enough in assuming the scale of the tsunami and that its preparedness was insufficient.

But what is conspicuous in the report is Tepco's attempt to evade its responsibility for the catastrophe and to minimize legal risks in compensating nuclear crisis victims and in dealing with lawsuits over the disaster.
