The Great East Japan Earthquake and the following tsunami caused unprecedented damage
to NTT’s service and facilities, and the NTT
Group expended unprecedented efforts to
restore services. The result was that almost all
services were restored by the end of April
2011, a month and a half after the earthquake.
With the lessons learned, and the recognition
that the importance of ICT and telecommunications infrastructure will continue to increase
in our modern society, NTT will continue studies to improve its facilities by developing better countermeasure with future disasters in mind.
