On June 9, 2011, we received an instruction document*, "Installment of
treatment facility and storing facility of water including highly
concentrated radioactive materials at Fukushima Daiichi Nuclear Power
Station (Instruction)" from Nuclear and Industrial Safety Agency (NISA) of
Ministry of Economy, Trade and Industry.
                                    (Previously announced on June 9, 2011)

Based on the instruction, we have been treating the accumulated water
containing highly concentrated radioactive materials in the Centralized
Radiation Waste Treatment Facility. We would like to announce that we have
summarized the latest situation of storing and treatment of accumulated
water containing highly concentrated radioactive materials, and reported
it to NISA today.

                                                                       END

     We have provided a Japanese press release version of the instruction
     document received from NISA. However, at this time we have reserved
     the right to not provide an English version due to potential
     misunderstandings that may arise from an inaccurate rendering of the
     original Japanese text. 
     We may provide the English translation that NISA releases in our
     press releases. However, in principle we would advise you to visit
