On June 22, 2011, we received an instruction document, from Nuclear and 
Industrial Safety Agency (NISA), entitled "Instruction to submit reports 
related to injection of nitrogen to the reactor containment vessel of Unit 
2 at Fukushima Daiichi Nuclear Power Station". * 
                                   (Previously announced on June 22, 2011)

Subsequently, regarding the injection of nitrogen to the reactor 
containment vessel of Unit 2 at Fukushima Daiichi Power Station, we have 
compiled a report that we will start the injection as early as possible 
after the preparation of necessary work environment and the environment 
impact due to the injection is below the exposure dose limit (1mSv per 
annum) to the general public, and have reported to NISA yesterday.

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 the NISA 
website for timely and accurate information.
