The newly appointed president of Tokyo Electric Power Company Holdings Inc. said Monday he will push through reforms to put business back on track, while fulfilling the firm's responsibilities over the 2011 disaster at its Fukushima nuclear power plant.

"We will carry out reforms and contribute to the development of the energy industry. We will also work to reconstruct our business to meet the expectations of the people of Fukushima and our customers," Tomoaki Kobayakawa said in a news conference also attended by current President Naomi Hirose, who has served in the post since 2012. Kobayakawa will take over in June.

Tepco decided to revamp its top management to seek a breakthrough in its stalling turnaround plan, with massive costs stemming from the disaster at the Fukushima No. 1 nuclear power complex continuing to weigh heavily.
