A money scandal involving top executives at Kansai Electric Power may have been going on for longer than reported.
The power utility said last week that company officials had received 3 million dollars in inappropriate cash and gifts from a public official. The payments were uncovered in a tax investigation.
The company's chairman Makoto Yagi told NHK on September 28 that he had received such funds from as early as 2006.
This contradicts the statement by Kansai Electric President Shigeki Iwane at a news conference a day earlier. He said the payments were made to as many as 20 officials starting in 2011 up to 2018.
The cash and gifts came from a former deputy mayor of Takahama town, which hosts one of the company's nuclear plants. The Takahama official, Eiji Moriyama, has since died.
Kansai Electric says its investigation so far was limited to the nuclear division. It will now broaden the probe to other business departments.
The company will hold another news conference on Wednesday.
