Rakuten AST aims to expand satellite-powered direct-to-device connectivity across Japan, strengthening telecommunications infrastructure and nationwide mobile coverage.
AST SpaceMobile (ASTS) and Japanese telecommunications giant Rakuten have announced the formation of Rakuten AST, a joint venture focused on developing a direct-to-device satellite communications network across Japan.
The initiative has reportedly secured approximately $1 billion in funding from Japan’s Ministry of Internal Affairs and Communications (MIC), representing a significant commitment to advancing the country’s next-generation telecommunications infrastructure.
The partnership aims to leverage AST SpaceMobile’s satellite technology alongside Rakuten’s established mobile network to enable ordinary smartphones to connect directly to satellites without requiring specialized equipment.
The technology could improve mobile connectivity in remote regions, mountainous areas, and locations where traditional cellular infrastructure remains limited or unavailable. It could also strengthen emergency communications during natural disasters, including earthquakes and severe weather events.
For AST SpaceMobile, the agreement represents another opportunity to expand its international footprint and commercialize its space-based cellular broadband technology through partnerships with established telecommunications operators.
Meanwhile, Rakuten stands to benefit from expanded network coverage and greater service reliability.
Looking ahead, the joint venture’s success will depend on satellite deployment, regulatory approvals, technical integration, and the ability to deliver reliable connectivity at commercial scale.
