SPACE WALKER

SPACE WALKER, Inc. is a Japanese aerospace startup founded in 2019 and affiliated with Tokyo University of Science, developing reusable spaceplane vehicles for sustainable commercial space transportation. The company is based in Tokyo, Japan, and aims to make space travel as accessible and routine as commercial aviation.

The company's flagship ECO ROCKET® spaceplane uses lightweight composite cryogenic propellant tanks, autonomous flight control systems, and biomethane as propellant to achieve carbon-neutral operations with a significantly reduced environmental impact versus conventional rocket propulsion. The biomethane fuel strategy positions SPACE WALKER as a leader in sustainable launch technology.

SPACE WALKER's long-term vision targets both suborbital tourism and point-to-point hypersonic transport markets, leveraging the reusable spaceplane architecture to reduce per-flight costs through rapid turnaround between missions. The company's Tokyo University of Science affiliation provides access to cutting-edge research facilities and talent, supporting the development of its advanced propulsion and airframe technologies.
