The utility did not have records of the incident in its daily logbook and failed to notify the government in an apparent violation of the law, company officials said, citing a recent in-house investigation.

This is not the first coverup of an emergency shutdown by a utility. Tokyo Electric Power Co. recently told the government it failed to give notice of emergency shutdowns at nuclear plants in Niigata Prefecture in 1992 and Fukushima Prefecture in 1985.
