Space-Based Connectivity in Japan

Additionally, Rakuten Mobile said the actual timing of the service launch and its scope is uncertain and subject to several factors, including those beyond the control of Rakuten and AST SpaceMobile.

Rakuten Mobile highlighted the increasing need for space-based communication services using Low Earth Orbit (LEO) satellites in Japan due to the high risk of natural disasters and the presence of many remote islands and mountainous regions.

The company mentioned that during the Noto Peninsula Earthquake of 2024, recovery routes were cut off, leading to a delay in emergency response efforts.

LEO Satellites Connectivity

Rakuten Mobile has invested in AST SpaceMobile under a partnership launched in March 2020, and both companies have been collaborating on a planned space-based mobile service to be provided in Japan in the future, utilizing LEO satellites to enable direct communication with commercially available smartphones.

Following the launch of AST SpaceMobile's LEO test satellite, BlueWalker 3, in September 2022, Rakuten Mobile and AST SpaceMobile completed two-way voice calls in April 2023, connecting Midland, Texas, to Tokyo, Japan, using standard, unmodified smartphones, the official release said.
