Takasago Thermal Engineering Co., Ltd.
Japanese engineering company developing lunar water electrolysis and thermal extraction of water from lunar regolith. Its electrolyzer flew on ispace's RESILIENCE lander in 2025, but the failed landing prevented the planned surface demonstration. A separate thermal-mining feasibility study concerns future extraction, not a demonstrated lunar water supply.
An organization's level is recorded separately and is not a ranking of its linked missions' results. How the ladder works.
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 |
| Oxygen | Targeted | work aimed at it |
Demonstrated
Built water-electrolysis equipment and delivered it for ispace Mission 2. The host failed to land; hydrogen and oxygen production on the lunar surface was not demonstrated. ispace states that Kurita supplied the experiment's ultra-pure water; this was not water extracted from the Moon.
Claimed or planned
Developing thermal mining to heat icy lunar regolith and recover water. The May 2025 ispace agreement covers feasibility and possible future rover deployment; it does not establish a booked flight or completed extraction demonstration.

ispace - Takasago Thermal Engineering MoU on lunar thermal mining feasibility
ispace announced an MoU with Takasago Thermal Engineering for a feasibility study toward demonstrating Takasago's thermal-mining water-extraction technology, still in research and development, on a future ispace rover.
Company statements only. No independent or government source is recorded here.
Sources (1) and evidence gaps
The agreement aims to conduct a feasibility study for joint technology development with the goal of demonstrating the extraction of water on the Moon.
- The feasibility agreement does not establish completed thermal extraction or a committed flight.
Open evidence gaps
- No published thermal-mining extraction yield, energy budget or integrated lunar-environment test result was verified.
- No assigned mission or launch commitment for a thermal-mining payload was found in the reviewed sources.
- The company's English space page says the HAKUTO-R programme concluded in December 2025; the June 9 release reports the failed June landing. These are not interchangeable event dates.
