Disaster Message Board Service
KDDI and Okinawa Cellular Telephone Company provide a Disaster Message Board service, which can be used for safety notifications with family members, relatives or acquaintances in times of disaster.
When a major disaster occurs, au mobile phone subscribers residing in the disaster-stricken area can use the Disaster Message Board established on EZweb/IS NET/LTE NET to register their personal safety information. This registered safety information can then be viewed from anywhere in Japan, via means such as on EZweb/IS NET/LTE NET or over the Internet. Furthermore, we provide a function that enables subscribers to send email notifications to pre-designated family members and/or acquaintances when the subscriber registers on the Disaster Message Board. In addition, it is also possible to check safety information over the Internet.
From a PC or other carriers' mobile phones, access from the following URL.
Linkage with "Google Person Finder"
You can access "Google Person Finder" offered by Google at the time of a disaster. "Google Person Finder" is a tool which helps people register, search for, and access safety information (information about yourself, family members, and friends) by searching the name of a person in a disaster. You can easily access the tool from the top page of the Disaster Message Board.
All-carrier search feature (Linkage with "Disaster Emergency Broadband Message Board (web171)" is now available)
"All-Carrier Search Service" became available on August 30, 2012. With this service, safety information registered on the au Disaster Message Board is searchable across all carriers, including NTT East/West and five mobile phone and PHS carriers. Launch of this service enables users to search safety information registered on the disaster message boards of five mobile phone and PHS carriers as well as NTT East/West at once from au Disaster Message Board. In the event of a major disaster, use the Disaster Message Board service more than before.

Information about using mobile phones when a disaster occurs
An overwhelming volume of telephone calls when a disaster such as an earthquake or accident occurs can make it difficult to get through on calls in the disaster-stricken area. Consequently, there may be some hindrance when attempting to register or check safety notifications, or when trying to contact the fire department or police. As a telecommunications carrier, KDDI strives to secure telecommunications through a variety of means, such as providing the Disaster Message Board, controlling network appropriately, and offering priority calls in times of disaster. In order to facilitate the smooth use of emergency telephones in the disaster-stricken area, we respectfully request that you refrain from making non-urgent calls or redialing continuously. Instead, we ask for your understanding in waiting for a while before trying again to make your call. Thank you.
For further information regarding the use of phones when a disaster occurs, please refer to the Website of the 'Telecommunications Carriers Association.'
