We are pleased to announce the completion of the renovation for Shiba Shirokane Hills, a residence nestled in the tranquil, upscale neighborhood of Shirokanedai—an area rich in greenery and culture, adjacent to Tokyo Metropolitan Teien Art Museum and the Institute for Nature Study.

The ceiling is gently curved, allowing natural light from the windows to blend seamlessly with delicate indirect lighting. This combination creates a soft, ambient glow and nuanced shadows that gently envelop the entire space.

Carefully selected materials in calm, muted tones were used for the walls and flooring. By harmonizing these elements in both color and texture, we aimed to create a refined and serene living environment.

We are pleased to announce the opening of “HAMANOYU Edo-Yu”, a new compact public bathhouse designed and supervised by Kubo Tsushima Architects, on Monday, April 21, 2025, in Nihonbashi, Chuo-ku, Tokyo.

Offering just the right warmth, the right amount of space, and a perfectly measured sense of time, this small-scale super sento (a modern style of large public bath facility unique to Japan) delivers a new kind of bathing experience that cannot be found at home. Thoughtfully designed to embrace comfort without excess, it brings together the essence of communal relaxation in the heart of the city.

Located within “iiyu HAMACHO”, a 10-story mixed-use building that combines a super sento on the 1st to 3rd floors and a 28-unit residential complex above, the project aims to create a place of rest and connection for a diverse range of people—from local residents and office workers to neighborhood visitors. It aspires to become a new cultural hub of comfort, communication, and gentle liveliness within the community.

Our project “Villa of Water Mirror” has been featured in the Casa BRUTUS special edition Japan’s Most Scenic Stays (published by Magazine House).

The property is introduced as one of 142 hotels where you can fully immerse yourself in Japan’s majestic natural beauty.

This unique and richly illustrated volume by renowned illustrator and writer Hiroshi Miyazawa explores exceptional hot springs, public bathhouses (sento), spas, and saunas across Japan—each designed by notable architects to offer a superior bathing experience.

The book introduces “yukemuri architecture”, or “steam-filled architecture,” focusing on built environments that enhance relaxation through thoughtful spatial sequences, tactile materiality, scenic views from the tub, pathways of air and wind, and carefully composed lighting. From the changing room to the bath itself, every aspect is analyzed and hand-drawn in detail, offering readers an immersive and architectural perspective on Japan’s bathing culture.
