ArkEdge Space

Micro-satellites · Satellite infrastructure · Koto, Tokyo

ArkEdge Space is a Tokyo-based company, established in July 2018, that designs, builds and operates micro-satellites and constellations. Its satellite platforms support Earth observation, communications, positioning and navigation, lunar infrastructure and deep-space exploration for customers including space agencies, researchers and businesses.

Its services cover constellation design, access to space and operations, hosted-payload missions for in-orbit demonstration, satellite components and software, and a ground station in Shizuoka operated from its Ariake headquarters. In February 2025 it raised JPY 8 billion in a Series B round led by Incubate Fund to expand satellite mass production and its constellation businesses.
