Service introduction
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 to register their personal safety information. This registered safety information can then be viewed from anywhere in Japan, via means such as on EZweb 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.

- 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.'
