Humans need to be more sensitive to personal hygiene than ever before. According to one survey on restroom use, 48% opened the door with their foot, 39% closed the door with their elbow, and 64% of people said they did not want to touch anywhere when using the restroom.

Hi Toilet is the world's first contactless toilet. In order to take the existing image of the hygenic Japanese public restrooms to the next stage, we developed a hands free toilet that can be fully operated using your voice.

Hi Toilet is the world's first contactless toilet. In order to take the existing image of the hygenic Japanese public restrooms to the next stage, we developed a hands free toilet that can be fully operated using your voice.

Hi Toilet is currently available to the public semi-permanently in Shibuya, Tokyo. Through repeated trial and error, we have designed a truly universal restroom that is accessible by everyone that can be used for years to come.

The system is equipped with multi-directional microphones designed for acoustics, a PC connected to the Internet, and proprietary software that uses Google and Apple APIs so the user can speak voice commands from any position in the restroom.

The final design was completed through repeated trial and error of training the AI and positioning the mics to create a truly user-friendly experience.

The spherical design replaces the air in the room after each use to create a new benchmark in ventilation engineering.

By combining the contactless experiential design with the architectural design with clean air in mind, we created a public restroom that meets the needs of today.
