Yakushima Island is a natural paradise in southern Japan.
This innovative housing applies "regenerative architecture" to reconceptualize the relationship between human habitation and this nature. The name Sumu means both "to live" and "to become clear," expressing its core concept of living in a way that positively impacts the landscape.
Rather than being a discrete site, the design takes a holistic view of the entire river basin, from the mountains to the sea, making a positive contribution to natural processes.
It applies "regenerative architecture," a new approach developed that combines traditional Japanese civil engineering with contemporary technology.
The key considerations in the design are:
1. Designing the underground environment
2. Orientating buildings based on in-depth understanding of water and air flows through the landscape
3. Creating an ongoing connection with nature through architecture
4.Off-grid energy from solar power
5. Several separate buildings layout respects the original natural elements.

Sumu's design changes our relationship with nature. Its unique approach has the potential to accelerate environmental initiatives if more widely applied.

"tono" is a word that means "with" or "relationship" in Japanese.
We will create a good relationship between nature and people through buildings.
Humans are a kind of microbes that live on this earth. If the earth of this planet is kept healthy by microorganisms, what can humans do? And what can architecture and spatial design contribute to Based in Yakushima Japan,
We design "Regenerative Architecture" which enriches the environment by utilizing the fungi found in the soil.

We are a regenerative architectural design office “tono”.
