Tokyo Seeks Domestic Alternative To Foreign-Controlled Satcom

The Japanese government is moving forward with plans to establish a domestically owned and operated D2D satellite network, known as J-LEO, with an estimated cost of ~$2B. The Ministry of Internal Affairs and Communications has allocated ~$1B in subsidies for the project, which aims to achieve a nationwide rollout by March 2029. The J-LEO network will provide a domestic alternative to foreign-controlled satellite networks, such as SpaceX’s Starlink, and will require companies to meet specific conditions, including achieving a nationwide rollout and completing all network and data control domestically in Japan. This development was first reported by Payload Space.
