Lawyers on Feb. 29 are expected to indict three former executives of Tokyo Electric Power Co. on charges of professional negligence resulting in death and injury in connection with the 2011 Fukushima nuclear disaster.

The indictment mandated by a citizens panel will be filed at the Tokyo District Court by lawyers serving as prosecutors.

Tsunehisa Katsumata, a 75-year-old former TEPCO chairman, and two former vice presidents, Sakae Muto, 65, and Ichiro Takekuro, 69, led the utility when the Great East Japan Earthquake and tsunami on March 11, 2011, triggered the meltdowns at the Fukushima No. 1 nuclear power plant.

The indictment will say the three former executives were aware that such a large tsunami could strike the coast of the Tohoku region, but they did not take measures to protect the nuclear plant.

The indictment will also argue that their failure to carry out their professional duties led to the deaths of patients at hospitals in mandatory evacuation zones as well as injuries to other residents during the evacuation.

A criminal complaint was filed against the three former executives by residents and citizens groups.

The Tokyo District Public Prosecutors Office in September 2013 decided not to indict the former executives, saying it was difficult for TEPCO to forecast such a large-scale natural disaster hitting the nuclear plant.

However, the Tokyo No. 5 Committee for the Inquest of Prosecution in July 2014 overrode the prosecutors’ decision, and sent the case back to them for a further look.

But the prosecutors again decided not to indict the three.

The citizens panel in July 2015 again overrode the decision, saying the three former executives should face mandatory indictment and be tried in court.

Court-appointed lawyers will serve as the prosecutors in the trial.
