About
Interstellar Technologies (インターステラテクノロジズ) is Japan's pioneering private space transportation company, founded with the mission of 'providing space infrastructure used by society.' The company achieved a historic milestone as the first Japanese private company to independently reach outer space with its MOMO observation rocket, and is now developing ZERO — a dedicated orbital launch vehicle designed specifically for small satellites. ZERO offers flexible launch services ranging from dedicated launches to rideshare missions, enabling small satellite operators to reach their desired orbits on their preferred schedules. In parallel, Interstellar Technologies is entering the satellite communications market with its DECA satellite program, targeting high-speed, high-capacity broadband connectivity for smartphones, automobiles, and other devices — forming a vertically integrated ecosystem that maximizes synergies between its rocket and satellite divisions. Having raised over ¥20.1 billion in Series F funding and successfully passing government-backed SBIR stage-gate reviews, Interstellar Technologies is scaling manufacturing capabilities across Japan, including a new Tohoku branch. The company serves satellite operators, research institutions, government agencies, and commercial enterprises seeking affordable, reliable access to orbit, positioning Japan as a competitive player in the global commercial space market.
