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 Signature Suite
The Altaris Suite represents the fullest expression of Kengo Kuma's brief for Altaris Tokyo: a private residence of extraordinary architectural discipline, occupying 205m² across the building's highest residential floor. The principal salon's floor-to-ceiling glazing presents a panorama from the Imperial Palace gardens to the distant ridge of the Japanese Alps — on a clear winter morning, Mount Fuji is visible. A private meditation garden; a tea ceremony room designed with the full rigour of the chashitsu tradition; a master bathroom combining an Oya stone walk-in shower with a deep hinoki wooden soaking tub. A dedicated butler manages every element of the suite's operation, twenty-four hours a day.

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.
