Kansai Electric Power Co. admitted Friday that 20 people, including its top executives, received a total of ¥320 million in money and goods from an official of a Fukui Prefecture town that hosts one of the company's nuclear power plants.

The payouts came over a seven-year period from 2011, the company said.

Kepco President Shigeki Iwane, 66, said those involved tried to return what they received but were not immediately able to do so because the former deputy mayor of Takahama refused.
