Headquartered in Taiki Town, Hokkaido, the company also operates development sites in Tokyo, Fukushima, Obihiro, and the Muroran Technology Research Institute (located within Muroran Institute of Technology). Our sounding rocket MOMO achieved the first and only spaceflight by a private Japanese company, and we are now intensifying the development of our next-generation small satellite launch vehicle, ZERO. In September 2023, we secured 2 billion yen in funding after being selected for the SBIR (Small Business Innovation Research) program by the Ministry of Education, Culture, Sports, Science and Technology. In March 2024, we signed a basic agreement with JAXA for procurement of launch transportation services. In April, we signed a contract with Italian venture company D-Orbit, which specializes in logistics services for small satellites, for future launches. These milestones are accelerating our business towards the launch of ZERO.
