KDDI Corporation would like to express its deepest sympathy and condolences to the victims of the Great East Japan Earthquake.
The Tohoku Region Pacific Coast Earthquake that occurred at 14:46, March 11, 2011 caused major damages to KDDI's communication facilities.
We would like to apologize for the trouble caused to customers using KDDI's communication services.
Immediately after the earthquake, KDDI established the Disaster Countermeasures Office at our headquarters and the Local Disaster Countermeasures Office at our TOHOKU Administration Office to grasp the situation of damages. In addition, KDDI fetched vehicle-mounted satellite base stations and mobile power supply vehicles, as well as support teams, fuels, and relief goods to establish the system to restore the services in the damaged areas at early stage.
In collaboration with group companies and associate companies, KDDI promoted early restoration of communication services through rerouting and restoration of main transmission lines and repair of base stations.
As a result, about 91 percent of au mobile phone base stations and about 99 percent of fixed-lines have been restored as of April 7, 2011.
As for the au mobile phone base stations, we intend to expand the zones of conventional base stations and utilize satellite entrances and wireless entrances to recover the areas of coverage to the same level of before the earthquake, except for the limited areas near Fukushima Nuclear Power Plant, by April 30, 2011. 
Simultaneously, we plan to restore the communication quality of before the earthquake by September 30, 2011, by constructing new base stations, except for the limited areas near Fukushima Nuclear Power Plant.
For customers who cannot use the fixed-line communication due to problems with the facilities within houses, we intend to restore the services quickly through substitute means.
