Universal Design for Space Tourists
We provide “Off-the-world” universal design criteria for realizing space tourism age and for everyone work and live in space.

Extraterrestrial and Extreme Environment Habitation Design
A wide spectrum of designs which ranging from extreme environment on Earth like Antarctica base, desert house, underwater habitat, to space station, planetary surface habitat, etc.

f-Reliant House Design
Research on self-reliant house and post-disaster supportive house design. Meanwhile, proposing to isolated, aging, and vulnerable areas or islands and help shaping next resilient society globally.
