Calls are growing in political circles — both locally and nationally — for Kansai Electric Power Co. to reveal the full extent of the graft related to the gift giving scandal and one of its nuclear plants that forced its chairman and other executives to step down.

Even as the company's board endorsed Wednesday resignations by Chairman Makoto Yagi and Vice President Ikuo Morinaka, many are dissatisfied, saying the company must take greater responsibility including a complete reshuffle of its management team.

President Shigeki Iwane said he will step down the same day a third-party panel releases results of an investigation into the gift scandal.
