THE TOKYO TOILET is a project by the Nippon Foundation to transform 17 restrooms in Shibuya Ward into public restrooms that are comfortable for everyone regardless of gender, age, or disability, with the aim of creating a society that embraces diversity. With the full cooperation of Shibuya Ward, 16 creators from Japan and abroad are participating in the project, proposing a new society in which everyone can spend their time comfortably, each with their unique design and creative abilities. The concept of the public restrooms, in which MEDUM participated in the exterior design with Kazoo Sato and the TBWA\HAKUHODO Disruption Lab team, is “Voice Command”, in which all operations are controlled by voice commands. The restroom, which employs voice-recognition technology, allows users to not only open and close the door and operate the toilet bowl, but also play music, making it a clean and enjoyable place to spend time. The entrance is laid out in the rear so that the architecture appears as a simple white sphere from the front. Highly visually recognizable pictograms were placed on the front exterior wall to maintain a simple appearance and easy-to-understand human traffic flow. In addition, lighting installed around the foot of the sphere illuminates at night, softly illuminating the surrounding area, making it accessible even in the dark hours. The pure white sphere with a maximum ceiling height of 4 m is also shaped to control air flow and prevent odors from lingering, and is equipped with a 24-hour ventilation system that combines natural air supply and mechanical exhaust ventilation. The large white sphere that appeared in the city was designed as a symbol of cleanliness, dispelling the image of dark, dirty, and scary public restrooms that have tended to be associated with them in the past.
