We had been studying to implement sampling surveys on the ocean soil, 
completed preparations and conducted the surveys on April 29, 2011. 
                                     (Previously announced on May 3, 2011)

We conducted a nuclide analysis of radioactive materials contained in the 
ocean soil sampled on December 11. As a result, radioactive materials were
detected as shown in the attachment.

Today, we reported the results to NISA and the government of Fukushima 
Prefecture.

We will continuously conduct the same sampling surveys.
