Key Findings
Leading Japanese space startups, iSpace and Astroscale, have demonstrated significant progress in their respective domains of lunar exploration and in-orbit servicing, underpinned by successful multi-billion yen funding rounds. iSpace secured ¥19.6 billion in October 2025 and was chosen as a key partner for Japan’s Space Strategy Fund lunar water exploration satellite project. Astroscale, specializing in orbital debris removal, announced a ¥12.16 billion funding round in the U.S. in May 2026, bringing its total raised capital to over ¥60.16 billion. These developments signify Japan’s growing influence in the international space industry and its commitment to advancing both lunar surface access and sustainable space operations.
Technical & Business Details
- iSpace: The company is focused on developing lunar landers and rovers, aiming to provide lunar cargo transport and data collection services. Its ¥19.6 billion funding round in October 2025, equivalent to approximately $130 million, solidifies its position as a critical partner for the lunar water exploration satellite project driven by Japan’s national space strategy. This engagement highlights iSpace’s expanding role in Japan’s broader lunar ambitions.
- Astroscale: Aims to be a global leader in in-orbit services, including active debris removal and satellite life extension. In May 2026, Astroscale announced a significant funding round of approximately ¥12.16 billion (equivalent to around $80 million) in the U.S., increasing its total capital raised to over ¥60.16 billion (approximately $400 million). This capital infusion is earmarked for expanding its manufacturing capabilities for debris removal satellites and scaling its service offerings, contributing to a more sustainable space environment.
Background & Industry Context
Japan’s space sector is experiencing a period of dynamic growth, with private companies increasingly complementing government-led initiatives. Both iSpace and Astroscale are strategically positioned within major trends shaping the future of space: iSpace contributes to the emerging ‘lunar economy’ by enabling access to the Moon’s surface, while Astroscale addresses ‘space sustainability’ through critical in-orbit services. Their respective advancements are vital for ensuring long-term access and commercial viability in space.
Strategic Significance & Outlook
For iSpace, successful execution of its lunar missions and continued development of its transport capabilities will be crucial for realizing commercial lunar access, especially as interest in lunar resource utilization and habitat construction grows. Astroscale’s services are becoming increasingly critical as orbital debris proliferation poses a significant threat to operational satellites. By providing solutions for a safer and more sustainable orbital environment, Astroscale is not only creating new market opportunities but also contributing to global space security. The ongoing success of both companies in securing funding and advancing technology is instrumental for Japan to assert its leadership in the global space market.
