Plaintiffs have appealed a ruling handed down by the Tokyo District Court in mid-September that found three former Tokyo Electric Power Co. executives not guilty of professional negligence. A class action lawsuit against the executives claimed they had failed to apply the proper safety measures to prevent the 2011 disaster at the Fukushima No. 1 nuclear power plant, despite being aware of the devastating effect tsunami would have.

The disaster upended daily life as local residents knew it and tore apart the social fabric of societies and communities around the area. Eight and a half years on, the victims are still grappling with the loss of their homes, and are turning to the courts for answers and closure.

Ruiko Muto, the 66-year-old leader of the class action lawsuit against former Tepco executives, has tirelessly conducted talks around the country since the nuclear disaster in 2011, which saw three of the six core reactors of the Fukushima No. 1 power plant go into meltdown after massive tsunami struck the facility.
