On March 21st 2011, radioactive materials were detected from the seawater
around the discharge canal (south) of Fukushima Daiichi Nuclear Power
Station which was damaged by the 2011 Tohoku-Taiheiyou-Oki Earthquake.
This is the result of the sampling survey of radioactive materials in
the seawater which was implemented as a part of monitoring activity of
surrounding environment. We had informed the result to Nuclear and
Industrial Safety Agency (NISA) and Fukushima prefecture.
(previously announced)

On March 23rd 2011, we had conducted re-sampling survey to examine
the effect of radioactive materials in the seawater. We had informed
the result to Nuclear and Industrial Safety Agency (NISA) and
the government of Fukushima Prefecture, because radioactive materials
were detected as shown in the attachment.

We will continue to conduct same kind of sampling survey.
