両国の北斎通りに面する温浴施設〈江戸遊〉の増築プロジェクト。江戸遊は葛飾北斎ゆかりの地で江戸をテーマにした温泉スパ、都市型スーパー銭湯である（温浴スパ、サウナ、岩盤浴、エステ、お休み処などの複合温浴施設）。
ファサードは、江戸小紋柄のパンチングをあけた大きなのれんをイメージしたデザインで、既存棟と増築棟のジョイントを縦目地に隠すことで一体的にしている。高さ20mのファサードの低層部分を風になびいたかのように柔らかく曲げることで、のれんをくぐるという体験をよりダイナミックにしている。
女性風呂は、漂う雲の合間にいるようなイメージのデザインを考えた。掛け湯からはじまり、高濃度炭酸泉、ジェットバス、水風呂などさまざまな種類のお湯を楽しく巡れるよう、それぞれ形の異なる雲形の浴槽には高低差もつけ、お湯ごとに違った風情を感じられるように計画している。雲のような天井には、照明や排気口が組み込まれている。
北斎のもつ世界観にインスピレーションを得ながら、現代的あるいは近未来から見た江戸の世界の構築を目指した。（久保秀朗＋都島有美）
A hot bath facility that expresses Edo with a façade that resembles a curtain swaying in the wind
Ryogoku Yuya Edoyu is a spa facility facing Hokusai Street, located in between the Edo-Tokyo Museum and the Sumida Hokusai Museum. We designed an annex to the existing public bathhouse. Our addition increased the total floor space of the facility twofold. We furthermore completely renovated the facility while keeping a certain portion of the existing interior intact.
While staying true to Hokusai’s world, in our design, we also tried to emphasize the concept of the word “yu (Play)” in Edo-yu, which means “freely wandering and enjoying.” Our design thus allows the facility’s visitors to enjoy the experience of wandering through various “nooks of comfort” created throughout the bathhouse.
Our facade design seeks to recall the image of fresh, whitish-grey bathhouse Noren (split curtains hung outside the bathhouse entrance) wavering refreshingly in the wind. Aluminum panels punctured with an Edo komon pattern (Hokusai loved komon patterns, which are intricate dye patterns that were popular during the Edo period) contain vertical slits that blur the joint between the new annex and the existing building, making the two buildings appear as a unified whole. The seigaiha pattern (depicting waves in the blue ocean) pierced in the facade gradually disappears as it nears the upper floors of the building, representing the refined tastes of the people of the Edo period, for whom the intricateness of these patterns was a source of competition (for the more intricate the pattern, the more skilled the artisans that lords had). By connecting an urban scale with the more human scale of passing under a Noren, we dynamically represent the experience of moving from the modern city to the Edoyu world.
The annex is designed with no columns or beams through the use of an RC thick wall and floor structure. We designed small spaces through the use of bathtubs, furniture, finishing materials, ceilings, and differences in lighting environments – all so that they would form a continuous sequence. This allowed us to create a layered landscape upon which a maximum of 400 visitors can all enjoy and find their very own nooks of comfort.
For the women’s bath, we wanted to create a space of baths floating in the clouds. Starting with the kakeyu (water poured on oneself before entering the bath) to the high concentration carbonated bath to the jet bath to the water bath, we designed the bathtubs in unique cloud shapes at different heights so visitors can wander and enjoy the various styles of the baths. The cloud-like ceiling contains lighting and exhaust vents.
Spaces with varying functions, such as a rest area composed of four different sections, a hot stone spa & salon treatment area, and a co-working space called “yu work” (“yu ” means bath) in the old building that keeps the image of the former spa intact, were all designed around a central luminous ceiling and connected through a staggered passageway.
While our inspiration derives from Hokusai’s world, our goal was to construct the Edo world from a modern, or perhaps even near future, perspective. (Hideaki Kubo + Yumi Tsushima)
