NTT Docomo has entered into an agreement with Starlink Japan, GK to utilize the next-generation ‘Starlink Mobile V2’ satellite constellation. This partnership is designed to expand the ‘docomo Starlink Direct’ service, targeting enhanced connectivity for smartphones and IoT devices in regions lacking traditional 4G or 5G coverage, such as maritime areas, islands, and mountainous terrain.

While the service currently supports text messaging, the expansion aims to introduce high-speed internet capabilities, including web browsing and voice calls, by fiscal year 2028. For corporate clients, these services will be managed through NTT Docomo Business as part of the ‘NTT C89’ brand initiative to expand space-related business solutions.

Following the service’s launch on April 27, 2026, reports indicate significant adoption, with approximately 6.5 million connections recorded within the first three months.
