NTT Disaster Emergency Message Dial (171)

Disaster Emergency Message Dial is a voice message board that is provided by NTT for when an earthquake occurs.Thanks to the numbers of fixed-line telephones that there will be inside any disaster-stricken area, messages can be left for or played back to your relatives when the level of telecommunications traffic is high and it is difficult to get through.

• During a disaster: the recording time limit is 30 seconds and the storage period is 48 hours. Only 10 messages are permitted.
• Mobile phones: Mobile phone numbers (090, 080), PHS numbers (070) and IP telephone numbers (050) cannot be used as message boards.
• From overseas: message recording and playback cannot be used from overseas
