Kansai Electric Power Co. is considering introducing rules on punishments for executives following criticism of its leniency in the way six of them were reprimanded for receiving gifts from a former town official, sources close to the matter said Tuesday.

The Osaka-based utility is set to establish such rules also because President Shigeki Iwane has decided on punishment for himself in the scandal, in which 20 people at Kansai Electric received ¥318.45 million worth of gifts from the former deputy mayor of the town hosting one of its nuclear plants.

Last Wednesday, Kansai Electric subjected Chairman Makoto Yagi and former Deputy President Hideki Toyomatsu to a 20 percent cut in remuneration for two months for accepting ¥8.59 million and ¥110.57 million worth of gifts, respectively, from Eiji Moriyama, the late deputy mayor of the town of Takahama in Fukui Prefecture.
