Premier Room
A composed study in Japanese architectural restraint — Oya stone bathroom, hinoki cypress ceiling details, and the structural silence of ma applied to 38m².
Tokyo, Japan
Where Stillness Becomes the Highest Form of Service.
Altaris Guest Room
The Marunouchi Room applies the Japanese principle of ma — considered, purposeful emptiness — to the architecture of a contemporary guest room. Oya stone bathroom, hinoki cypress ceiling inlay, and washi-panelled walls frame a silence that is structural, not incidental. The city view from the floor-to-ceiling glazing presents Marunouchi's considered geometry; the room provides the stillness required to appreciate it.

Tokyo, Japan
A Kengo Kuma-designed tower above Marunouchi, minutes from the Imperial Palace grounds. Altaris Tokyo interprets the European grand hotel through the Japanese concept of ma — the discipline of considered emptiness — translating forty floors of hinoki cypress, hand-woven washi, and Oya stone into an atmosphere of profound, structural calm. Here, everything is present. Everything is precisely withheld.
ReserveDrawing from volcanic aquifers deep below Marunouchi, Onsen Altaris applies the deep intelligence of Japanese thermal therapy alongside precision physiological recovery. The temperature is engineered; the stillness is absolute.
