MISSION
TO BUILD SPACE INFRASTRUCTURE THE WORLD CAN TRUST
The future growth of the space industry and its ability to address Earth's challenges depend on driving innovation in infrastructure—rockets for space transportation and satellites as the hardware enabling space utilization. As a comprehensive space infrastructure company, we aim to lower barriers to space access and broaden its applications, ultimately contributing to a sustainable future for our planet through the potential of space.
ACHIEVEMENTS
7 Launches, of which 3 reached space successfully
1st Rocket developed by a private Japanese company to reach space
1st And only private company in the world utilizing liquid bio-methane fuel
HISTORY
In 1997, space enthusiasts from across the nation came together to explore the possibility of launching low-cost satellites into orbit using miniature rockets. This initiative eventually led to the concept of small rockets capable of deploying satellites weighing only a few dozen grams into orbit, which is the foundation of our current rocket development. It all began with brainstorming sessions in the humble confines of an apartment bathroom, where members conducted repeated experiments to ignite the first rocket engines. With no initial infrastructure, the team persevered, eventually establishing a base in Akahira City, Hokkaido. Today, our pursuit of this dream continues in Taiki, Hokkaido.
Founded Natsu no Rocket-dan, an organization dedicated to private space development, the forerunner of Interstellar Technologies.
