Founder of Bankrupt Space Venture SpaceWalker Reveals Critical Turning Point
SpaceWalker, a Tokyo-based space venture spun out from Tokyo University of Science, filed for bankruptcy in February 2026 after failing to commercialize its reusable spaceplane technology. Founder and former CTO Koichi Yonemoto identified a 2023 government subsidy of 2 billion yen as the critical turning point that led to the company's collapse. Initially operating with a lean team of eight engineers and modest funding, the substantial grant triggered rapid expansion, swelling the workforce to seventy employees, including many inexperienced fresh graduates. The company had aimed to develop 'Nagatomo,' a suborbital spaceplane for tourism, alongside experimental crafts 'Fujin' and 'Raijin.' Despite the space industry being designated a growth sector by the Japanese government, the sudden scaling overwhelmed the startup's management capabilities. Yonemoto expressed deep regret over the outcome, highlighting the dangers of rapid expansion fueled by public funds without sufficient operational infrastructure. This case underscores the challenges facing private space enterprises in Japan, even amidst strong government support and high ambitions for space tourism and satellite launch services.
