# Tenchijin Secures 100+ Municipal Water Contracts in Japan

Tenchijin Inc., a space-tech company originating from JAXA, has secured over 100 cumulative municipal contracts across Japan since April 2023 for its COMPASS KnoWaterleak solution. This satellite data and AI-driven water utility management service supports leak risk assessment, pipe renewal planning, and sewer inspection, addressing critical aging infrastructure challenges with cost-effective, data-driven preventive maintenance. The Ministry of Land, Infrastructure, Transport and Tourism and the Japan Water Works Association are key stakeholders in this sector. Tenchijin plans to launch a cloud-based version of KnoWaterleak in fiscal year 2027, which will expand accessibility for utilities nationwide and potentially increase procurement opportunities for technology providers in water infrastructure management.

- **Why this matters:** Municipal water utilities in Japan are increasingly adopting advanced satellite and AI technologies to modernize aging infrastructure and improve maintenance efficiency.
- Procurement professionals should note the growing demand for innovative digital water management solutions supported by government agencies and industry associations.
- The upcoming cloud-based release in FY2027 indicates expanding market opportunities for vendors offering scalable, data-driven water utility services.
- Organizations involved in water infrastructure modernization can leverage this trend to align proposals with government priorities on infrastructure resilience and cost reduction.
