Tokyo Electric Power, the operator of the Fukushima Daiichi power plant hit by the tsunami in March, announced on Friday an all time high $15bn net loss due to the disaster which destroyed four of its reactors.
The news was followed by the resignation of Tepco's president Masataka Shimuzu, and the head of the nuclear division, Sakae Muto, who were both criticised for their handling of the nuclear disaster.
“We feel sorry for the victims of the earthquake and tsunami. At the same time we want to sincerely apologise for our nuclear reactors in Fukushima causing so much anxiety, worry and trouble to society,” Shimuzu said at a conference.
Shimizu will be replaced by the company's managing director Toshio Nishizawa.
