Kurita Water Industries Ltd.
Tokyo-based water-treatment company (栗田工業株式会社), listed on the Tokyo Stock Exchange Prime market, that is applying its water-purification technology to future use of lunar water. In July 2026 it said JAXA had selected it, for the third year running, for Earth-based tests of the water-purification step of a planned lunar propellant plant. ispace has announced agreements with Kurita to carry a water-processing demonstration system on an ispace lunar mission after 2027 and to plan lunar water-supply business together, and in October 2025 announced a share allotment to Kurita of about ¥2 billion. The sources describe ground tests with simulated water and planned demonstrations, not processing of lunar material.

| Resource | Evidence | Meaning |

| Water ice | Targeted | work aimed at it |
Demonstrated
Non-ISRU work. Kurita refers to a demonstration of a water-recycling system at the International Space Station with JAXA. ispace says Kurita supplied ultra-pure water for Takasago Thermal Engineering's electrolysis device on its Mission 2 lander. These statements do not establish processing of lunar material.
Claimed or planned
Kurita says JAXA selected its proposal for Theme C, element prototype tests of the water-purification process, in JAXA's 2026 competition for detailed design and element tests of a ground demonstration plant toward a lunar propellant plant, after selections in fiscal 2024 and 2025. It will test removal of ammonia and methanol from raw water that simulates water extracted from lunar regolith and report to JAXA within fiscal 2026. ispace announced a March 2025 agreement to transport a Kurita water-processing system for demonstration tests on an ispace lunar mission after 2027, and a December 2025 strategic partnership on lunar water-resource business.

- No JAXA-published selection notice or contract record naming Kurita was found; no amount or currency is stated.
Open evidence gaps
- JAXA's own selection notice or contract record for Kurita's 2024, 2025 and 2026 work was not found; the selections are stated by Kurita. JGC Holdings' 22 July 2026 release confirms that JAXA selected its subsidiary in a competition with the same title but does not name Kurita.
- Kurita's own website refused this reader (the robots.txt request failed certificate verification on 2026-11-11), so its English corporate profile and its own releases on the ispace agreements were not read; name, address, founding month and listing come from the company profile shown on PR TIMES.
- No lander, mission or date is assigned to the water-processing demonstration system; ispace's March 2025 release says only 'an ispace lunar mission after 2027'.
- Completion of ispace's planned third-party share allotment to Kurita was not checked.
- No published results of the water-purification tests were found; Kurita says it will submit them to JAXA within fiscal 2026.
- Kurita is not linked as counterparty on ispace - Kurita Water Industries strategic partnership on lunar water resources, whose own missing-evidence note says Kurita was not recorded as an organization.
