Current Status of Restoration Following Tohoku - Pacific Ocean Earthquake

TOKYO, March 24, 2011 - As a result of NTT Group's full-scale, round-the-clock recovery efforts,
NTT Group companies have been steadily restoring services centered in the
Tohoku region that were disrupted by the March 11, 2011 Tohoku - Pacific
Ocean Earthquake in Japan. The efforts have included establishment of
Disaster Countermeasures Office in accordance with disaster prevention
operation plans based on the Basic Act on Disaster Control Measures. The
current status of restoration for major services is as follows.

(1) Nippon Telegraph and Telephone East Corporation ("NTT East")

<Current status of communication facilities>

The earthquake and tsunami disrupted commercial power supply and caused
equipment failure in approximately 1,000 exchange offices. NTT East responded
by deploying emergency batteries, emergency power generators and mobile
power-supply vehicles to supply power. However, some exchange offices
remained inoperable, resulting in the disruption of a total of approximately
1,470,000 circuits in telephone subscriber lines, ISDN and FLET'S Hikari
(FTTH) services as of 6:00 a.m., March 13 (JST). NTT East, with the help of
other NTT Group companies and construction companies, mobilized some 5,000
people in total to make an all-out effort to restore these services. By 1:00
p.m., March 23 (JST), approximately 90 percent of the exchange offices had
been restored along with the recovery of commercial power supply, leaving 93
exchange offices and approximately 155,000 circuits waiting to be restored.

    Total                    154,900                    1,473,500

Note: Figures exclude failures due to disruptions between customers and
NTT East exchange offices.

The 93 exchange offices yet to be restored include those with physical
damage, flooding or disruption of connection to backbone transmission lines
in areas severely impacted by the earthquake and/or tsunami, and those
located in the off-limits area surrounding the malfunctioning nuclear power
plant. For these reasons, the recovery of most of these exchange offices is
expected to require a significant amount of time.

To provide people affected by the earthquake and its aftermath with
communication means, NTT East has installed 2,076 special public telephones
in 615 locations available for use free of charge (as of noon, March 23

services "Disaster Emergency Message Dial 171" and "Disaster Emergency
