Tenchijin merges satellite big data with proprietary AI algorithms to deliver insights that make invisible ground-level risks and value visible. Its core product, the water-utility digital-transformation service “Uchū Suidokyoku,” launched in April 2023 and has already been adopted by numerous municipalities, surpassing 50 cumulative contracts by September 2025. Beyond water infrastructure, the company is extending its technology stack to agriculture and renewable-energy applications and is even developing its own satellites to build an end-to-end data platform. The newly raised funds will be directed toward hiring engineers, enhancing satellite-data analysis and water-resource-monitoring algorithms, expanding domestic and international sales networks, and strengthening its multi-satellite cloud data infrastructure. Branding and market-awareness initiatives are also planned. Headquartered in Tokyo’s Nihonbashi district, Tenchijin positions its mission as “optimizing human civilization through space big data.” Including the latest round, its total funding—equity and debt—now stands at roughly ¥1.9 billion.
