Lawyers for three former executives of Tokyo Electric Power Company Holdings Inc. called for their acquittal in their final defense plea on Tuesday in a negligence case stemming from the Fukushima nuclear crisis in 2011.

The defense team said that it was impossible for them to foresee the massive tsunami that engulfed the Fukushima No. 1 power plant and caused fuel meltdowns following a 9.0 magnitude earthquake that rocked the coastal Tohoku region.

The day after the nation marked the eighth anniversary of the March 11, 2011, disasters, the lawyers for Tsunehisa Katsumata, 78, Tepco chairman at the time of the crisis, and Ichiro Takekuro, 72, and Sakae Muto, 68, both vice presidents, told the Tokyo District Court they "do not recognize any predictability in the disaster."
