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.
