This innovative restroom concept emerged from a three-year study on public restroom behavior across Europe and the U.S., which revealed that most users try to avoid touching surfaces. Inside, there is a list of voice commands in both English and Japanese. To activate the system, users simply say "Hello, Toilet," which triggers an audio response, indicating the restroom is ready to accept further commands.
The building’s design is both visually appealing and promotes excellent air circulation.

The Tokyo Toilet Project: A remarkable example of how world-renowned architects and creative professionals came together to redesign public restrooms in the Shibuya district of Tokyo.

Since 2020, 17 unique structures have been introduced in Shibuya, each with its own concept, contributing to a shared goal—not only to revamp the appearance of public toilets but also to change people’s perception of them. Even in Japan, where public restrooms are known for higher hygiene standards compared to many other countries, they were still often considered uncomfortable and unappealing spaces.
