Information useful
in the event of a disaster

Free public wireless LAN is opened in case of disaster

In the event of a disaster, if there is no communication environment, quick safety confirmation and information collection cannot be performed. Therefore, a public wireless LAN (Free Wi-Fi) called “00000JAPAN” (Five Zero Japan) will be opened to areas where damage is large in the event of a large-scale disaster such as an earthquake or heavy rain. Each telecommunications carrier (docomo / Softbank / au (KDDI) etc.) will open "00000JAPAN" free of charge. In this site, we will inform you of such establishment status on a special site when a disaster occurs, so please check it.
