Japanese startup in Utsunomiya building deorbit devices that attach to rocket upper stages, plus re-entry and microgravity experiment hardware.
BULL Co. develops hardware for space debris mitigation and microgravity experimentation. Its primary technology is a post-mission disposal device that attaches to the upper stages of launch vehicles or satellites before they launch. Once the host vehicle completes its mission, the device deploys a mechanism to rapidly deorbit the hardware, preventing it from becoming long-term space junk.
The company is also developing low-cost reentry capsules designed to return small scientific payloads and microgravity experiments from space. Backed by Japanese venture capital, it works with domestic research institutions to test its drag-inducing technologies in orbit.
Yutaro Uno founded the company in 2022. It is headquartered in Utsunomiya, Tochigi Prefecture, Japan.

BULL signs deal to demonstrate HORN PMD device on EnduroSat satellite (launch planned 2027)
EnduroSat reported that it contracted with BULL to carry BULL’s HORN post-mission disposal device for an in-orbit demonstration. The post states the device will be flown on a 16U EnduroSat satellite, with a target launch in 2027 aboard SpaceX’s Transporter 22. The demonstration is positioned as validating deploy and de-orbit performance under real space conditions, supporting HORN’s supplier qualification for EnduroSat missions.
