Mobile Battery Manufacturers and Japan's Telecommunications Carriers Conclude Cooperative Agreement to Secure Power Supply for Areas Affected by Large-Scale Disasters

Companies collaborate to deliver portable power supply to evacuation centers and other sites during large-scale disasters

Tokyo, May 18, 2026 – Seven mobile battery manufacturers – Anker Japan Co., Ltd., INFORICH Inc., EcoFlow Technology Japan Co., Ltd., Elecom Co., Ltd., Owltech Corporation, CIO Co., Ltd., and Ugreen Japan Co., Ltd. ("mobile battery manufacturers") – and Japan's telecommunications carriers participating in the "Connect to Change" project^*1 – NTT Group,^*2 KDDI Corporation, SoftBank Corp. and Rakuten Mobile, Inc. ("telecommunications carriers") – today announced they concluded a cooperative agreement to secure power supply for areas affected by large-scale disasters.

Under this Agreement, starting June 1, 2026, the mobile battery manufacturers will procure and provide mobile batteries, charging cables and other equipment, which the telecommunications carriers will then deliver to evacuation centers and other sites based on local needs and the severity of conditions in affected disaster areas.

Objective of the Agreement

As society becomes increasingly digital, ensuring access to power in disaster-affected areas has become increasingly critical. Mobile battery manufacturers have long supported disaster victims by supplying portable chargers and other power equipment, but providing support on their own at affected areas has been a challenge.

Telecommunications carriers, by contrast, are widely active across disaster zones, supporting the provision of telecommunications infrastructure at evacuation centers and other locations. This agreement builds on that support structure, enabling the telecommunications carriers to deliver power supply equipment provided by the mobile battery manufacturers to improve access to power in the disaster-affected areas. With access to reliable power, evacuees will be able to charge their smartphones and other devices, allowing them to contact family and friends, and access essential information with greater peace of mind.
