We received an instruction "Collection of report pursuant to Section 67.1
of Act on the Regulation of Nuclear Source Material, Nuclear Fuel Material
and Reactors" from Nuclear and Industrial Safety Agency, Ministry of
Economy on April 13, 2011.
                                     (Already announced on April 13, 2011)

Thereafter, based on the instruction, we implemented study regarding
current seismic safety and reinforcement of reactor building for Unit1
and 4 at Fukushima Daiichi Nuclear Power Station, and marshaled the
results. Hence we announce that we reported to the Agency today.

We will report about the other Unit to the Agency as soon as the results
have been marshaled.

the following date of the decision even if it falls within sixty days from
the day following the date when you learn that the decision was made.

(Instructions from Ministry of Economy, Trade and Industry)
·Results of the earthquake-proof safety evaluations of primary
 containment vessels and reactor pressure vessels which are important
 facilities for the earthquake-proof safety, and reactor buildings which
 are indirect supporting structures for spent fuel pools at Fukushima
 Daiichi Nuclear Power Station using the possible earthquakes in the
 future for the input earthquake motion.
·Results of the studies of countermeasures such as antiseismic
 reinforcement work to the places where the earthquake-proof safety might
 not be secured in the current reactor buildings.
