We received a directive document titled "Action for water leakage from near 
the emergency reactor injection pump on the hill etc of Fukushima Daiichi 
Nuclear Power Station" from the Nuclear and Industrial Safety Agency (NISA).

                                   (Already announced on January 30, 2012)

We have investigated the cause of the leakage, and have developed and 
implemented the preventive measures. We announce that we have summarized 
the plan as well as the implementation status of the deicing measures and 
reported it to NISA today.
                                                                       End
