KDDI and Okinawa Cellular have officially launched au Starlink Direct, Japan’s first direct-to-cell satellite service, ushering in a new era of mobile connectivity powered by SpaceX’s Starlink satellite network.
Starting today, au users can access the service free of charge, with no application required. The service is initially compatible with 50 smartphone models, allowing devices to connect directly to satellites—no need for ground infrastructure or cell towers.
Seamless Connectivity Anywhere Under the Sky
au Starlink Direct ensures that as long as there is a clear view of the sky, users can stay connected—even outside of traditional coverage areas. Whether deep in the mountains, offshore, on isolated islands, or at remote campsites, users can send and receive text messages, share their location, and receive real-time emergency earthquake alerts.
The service also integrates with AI technology: Android users can interact with Google’s Gemini assistant by sending text-based queries, enabling them to get help with tasks like information searches and navigation—even in off-grid environments.
Closing the Gap in National Coverage
While au’s population coverage exceeds 99.9%, Japan’s rugged terrain limits its geographical coverage to just 60%. au Starlink Direct aims to bridge this gap by providing satellite-based coverage across the entire country—connecting the remaining 40% where traditional networks struggle.
KDDI says this move is a critical step in its mission to “connect the unconnected—wherever you can see the sky.“
Global First for Asia
The launch marks a historic milestone not only for Japan but for the entire Asia region. Speaking on the occasion, Gwynne Shotwell, President & COO of SpaceX, said:
“I’m very excited to bring direct-to-cell phone connectivity to Japan through KDDI, the first in Asia and one of the first in the world. Both Starlink and direct-to-cell are game-changing technologies, making connecting the unconnected simple and bringing potentially life-saving capability to the people of Japan for disaster and other emergency responses.”
As connectivity becomes increasingly vital in disaster preparedness, remote operations, and everyday convenience, au Starlink Direct represents a major leap forward in resilient mobile infrastructure for Japan—and a glimpse into the future of global telecom.
