Kansai Electric Power Co. said Wednesday that among 20 staff who received benefits from a former official of a town hosting one of its nuclear plants, two executives responsible for the utility's nuclear business were each given gifts valued at over ¥100 million.

The firm's disclosure of additional information about the money scandal, said to involve more than a dozen officials, has re-exposed collusive ties between the nuclear industry and government officials.

Of the ¥318.45 million worth of gifts received by employees of Kansai Electric, the largest amount of ¥123.67 million was given to managing director Satoshi Suzuki, followed by ¥110.57 million for former deputy president Hideki Toyomatsu, the company revealed.
