JAXA-Backed Venture Tenchijin Partners with Zenrin



Tenchijin, a space venture recognized by JAXA and based in Chuo, Tokyo, has announced its partnership with Zenrin Co., Ltd., headquartered in Kitakyushu, Fukuoka. The collaboration involves an agency agreement for the "Tenchijin Compass Space Water Bureau" in Japan, aimed at improving water management solutions through innovative technology and data utilization.

Background of the Agency Agreement



The "Tenchijin Compass Space Water Bureau" employs a variety of data, including Earth observation satellite data and other big data, to support sustainable water supply projects for over 30 municipalities. As Japan faces challenges related to the aging water infrastructure installed during the economic boom, issues like water leaks have become increasingly prevalent. This necessity calls for urgent response and modern solutions.

Through the implementation of the Tenchijin Compass, Tenchijin aims to broaden its contributions to local municipalities, helping to tackle the pressing issues affecting water services across the nation. The partnership with Zenrin is expected to enhance communication and engagement with many municipalities, creating an avenue for more effective responses to the current "water infrastructure crisis." Plans are advancing to ensure the sustainability of water infrastructure across Japan.

Insights from Zenrin



Zenrin, recognized for its expertise in map information services, commented on the significance of the partnership. The Japanese water supply sector struggles with challenges such as the increasing age of water pipes, low renewal rates, and a decreasing number of personnel. The Tenchijin Compass, utilizing satellite data and AI technology, has already been adopted by more than 30 municipalities to address these issues.

Zenrin's commitment lies in assisting government entities at both central and local levels to resolve regional challenges and improve operational efficiencies through mapping technology. By partnering with Tenchijin, Zenrin expects to accelerate the proposal of high-value solutions, thus contributing further to solving challenges faced by the water supply sector.
