Following KDDI’s network outage last month, Japan is looking to beef up backup systems to ensure that users will be able to access communications networks in times of emergency.

Leaders of major mobile carriers have stressed the need to work with each other to provide emergency roaming services, while the government is also becoming more serious about facilitating discussions on the issue.

“KDDI’s network disruption is not somebody else’s problem,” Nippon Telegraph and Telephone (NTT) chief Akira Shimada said at a news conference last week.
