ispace and KDDI signed a new basic agreement on November 12, 2026 to build a lunar communications network. The Tokyo companies will also study space industry promotion and talent development in Yamaguchi. ispace is a space startup that builds lunar landers, while KDDI is a major telecom operator.
Partnership scope
The agreement extends an earlier pact signed in March 2025. The partners will combine their technologies, facilities, operational knowledge, and customer bases for joint technical work and demonstrations. They will also address local challenges under KDDI's Alliance Park Project in Yamaguchi.
Company roles
ispace plans to offer its Lunar Connect Service using its own lunar orbiting satellite. It expects to launch the first satellite in that effort as early as 2027. KDDI will consider providing ground station functions, lunar surface mobile communications, and space optical communications.
Cislunar demand
Human activity, resource development, industry operations, and space situational awareness are expected to expand in cislunar space. Japan wants its own communications capability to support safe operations and economic security. The partners aim to connect the lunar surface, cislunar space, and the ground in one architecture.
Next steps include talks with the Japanese government and related agencies. ispace expects a lunar orbiter launch in 2027, a lander mission in 2028, and a south pole landing attempt in 2029. Joint Yamaguchi programs are also planned.
