With regard to the parameters related to each plant in Fukushima Daiichi 
Nuclear Power Station on our website posted since April 18th, 2011, we 
found that there are some mistakes in the data and therefore we reported it 
to Nuclear and Industrial Safety Agency (NISA) on April 24, an have 
continued checking data.
                                  (Previously announced on April 24, 2011)

Today, we compiled the results, confirmed that there is no safety issues, 
and reported them to NISA.
We also updated the data on our website by reflecting corrections and 
adding data newly confirmed. 
*English version of parameters related to plants is now being developed. 
We apologize for the inconvenience caused. It will be posted as soon as it 
is prepared. ( The parameters related to plants )

We will review our checking systems for data of parameters related to 
plants to prevent mistakes.
