Three former executives of Tokyo Electric Power Co. will be indicted Monday for the allegedly failing to take measures to prevent the tsunami-triggered disaster at the Fukushima No. 1 nuclear plant, a lawyer in charge of the case said Friday.

The three, who will face charges of professional negligence resulting in death and injury, are Tsunehisa Katsumata, 75, chairman of Tepco at the time, and two former vice presidents — Sakae Muto, 65, and Ichiro Takekuro, 69.

Prosecutors originally decided not to indict the men in September 2013, but the decision was overturned in July 2015 by an independent committee of citizens that mandated the three be charged on the grounds they were able to foresee the risks of a major tsunami prior to the disaster.
