JGC Holdings Corporation
Yokohama-based Japanese engineering group. Its overseas EPC (engineering, procurement and construction) operating company, JGC Corporation (日揮グローバル株式会社), has carried out successive JAXA-contracted, Earth-based design studies for a lunar propellant plant that would extract water from lunar regolith and produce liquid hydrogen and liquid oxygen. In July 2026 JAXA selected JGC Corporation for detailed design and component prototype testing of a ground demonstration plant, with results due to JAXA by 31 March 2027. JGC Holdings cites a JAXA draft plan to begin building a lunar demonstration plant in the 2030s. JAXA’s 22 July 2026 selection notice names the operating company 日揮グローバル株式会社 (JGC Corporation) for water-extraction component prototype testing and says a contract is to be concluded. That notice is not a completion or payment record and gives no yen amount; the 31 March 2027 due date remains attributed to the company release.

Resources and evidence
Each resource shows the highest step primary sources support. How the ladder works.
| Resource | Evidence | Meaning |
|---|---|---|
| Water ice | Targeted | work aimed at it |
| Regolith | Targeted | work aimed at it |
| Oxygen | Targeted | work aimed at it |
Demonstrated
Earth-based only. JAXA-contracted conceptual studies, design work and breadboard (component prototype) development and testing for a terrestrial pilot or demonstration plant. No test results were published in the sources reviewed; no hardware has flown and no lunar water or propellant has been produced.
Claimed or planned
JGC Holdings says the plant would extract water from lunar regolith and produce liquid hydrogen and liquid oxygen as fuel for crewed lunar landers and hopping vehicles. It cites a JAXA draft plan to start site surveys and construction of a lunar demonstration plant in the 2030s and full propellant-plant operation by 2040.

Open evidence gaps
- Contract values for the JAXA awards are not published in the releases reviewed.
- No results of the 2024-2025 breadboard tests or preliminary design (due to JAXA by 31 March 2025 and 31 March 2026) were found in the sources reviewed.
- JAXA’s 22 July 2026 selection notice was reviewed. It names the operating company, not JGC Holdings, and does not establish completed tests, payment or a contract value. The notice does not state the company release’s 31 March 2027 due date.
- The releases describe water 'contained in' or extracted from regolith; it is recorded as water_ice (lunar polar icy regolith) by inference, not because the release says 'ice'.
- The JAXA contracts are held by the operating company JGC Corporation, not by JGC Holdings itself; this profile covers the group, and the subsidiary has no separate record.
- Whether and when the listed group itself previously used the name 'JGC Corporation' is not documented in the sources reviewed; older material under that name may refer to the group rather than the current operating company.
