Moon Today.
Mars Tomorrow
Building the infrastructure for human life beyond Earth.
About Us
iSaisei Corporation is a deep-tech company developing space infrastructure for human presence beyond Earth.
The company operates in the field of modular habitats and expandable architectures, designing scalable solutions for long-duration missions on the Moon and in cislunar space.
Within the emerging space economy, iSaisei works to transform space from an environment of exploration into an operational infrastructure.
A new space infrastructure paradigm
We are developing intelligent modular habitats designed for scalability, rapid deployment, and integration within future lunar missions.
Engineering for extreme environments
OXYGEN integrates advanced materials, multi-layer structures, and intelligent systems to operate reliably in the harsh conditions of the lunar surface.
From Earth to the Moon and beyond
Our vision is to enable a stable human presence beyond Earth, starting from the Moon and building the foundations for future space infrastructure.
O.L.H. – Oxygen Lunar Habitat
A modular, expandable habitat system for long-duration human presence on the Moon.
Why this matters now
The return to the Moon
Government programs and private missions are accelerating the return to the Moon, creating the need for sustainable human presence.
The missing infrastructure layer
iSaisei approach
iSaisei is developing modular and expandable habitat systems designed to address this gap, starting from near-term validation and progressing toward operational deployment.
Recognized by the Moon Village Association
While launch systems and missions are evolving rapidly, scalable infrastructure for long-duration human presence remains a critical gap.
Space is no longer a destination.
It is a place to stay.
