The Tokyo Urban Meditation Cabins are located in the busy landscape of Tokyo, designed to provide a space for meditation and quiet reflection. Inspired by Toro Nagashi, Japan's Glowing Lantern Festival, the design creates the illusion that the structure floats above the ground. This approach reduces the visual bulk of the structure and encourages users to engage more deeply with their surroundings. The goal is to foster a peaceful atmosphere where individuals can unwind.

Structural Aesthetics

A key feature of the design is a closed water circuit that runs along the outside of a wavy polycarbonate wall. This flowing water creates a soothing sensory experience. It flows into a bronze tank, which not only serves a practical purpose but also stands out as a central element of the design. Inside this tank, the meditation seat and foot support are shaped like stones, enhancing the connection to nature and creating a calming environment for users.

Lighting and Ambiance

The project also considers how the cabins interact with light, especially at night. The underwater lighting brightens the flowing water and the wavy wall, resulting in a gentle twinkling effect that resembles lanterns. This lighting choice helps to make the cabins inviting and peaceful, transforming them into features of serenity in the bustling city atmosphere.

Material Considerations

The materials chosen for the design reflect a commitment to sustainability and functionality. The polycarbonate walls allow for natural light to enter, while the bronze tank adds warmth and visual interest, developing a unique patina over time. The structure is supported by stainless steel, which is durable in urban environments. Cortene steel and precast concrete provide strength and stability, while an iron spring system enhances usability, ensuring that the design accommodates a range of activities.

Water Interaction Details

The presence of flowing water, combined with the distinctive shape of the wavy wall, offers an engaging and interactive environment. Users can connect with the space and find moments of calm amidst the busy city life. This thoughtful blending of function and sensory experience helps cultivate a setting that promotes mindfulness and reflection, emphasizing the relationship between the built environment and the natural world.
