Hi Toilet, designed by TBWA\HAKUHODO wins 2022 Good Design Award

12 October 2022

“Hi Toilet”, the world’s first voice-operated public toilet, designed by TBWA\HAKUHODO, was awarded at the 2022 Good Design Award.

Designed as part of THE TOKYO TOILET project by the Nippon Foundation, this public toilet distinguishes itself via its “Voice Command” operational capabilities. With the original voice-recognition technology, the users can open and close the door, flush, activate the handwashing, and even play the music by voice. With this technology, Hi Toilet aims to provide a sense of comfort, clean and fun. The bright white spherical building will feature a ceiling height of up to four meters, which is also shaped to control airflow and prevent odors from stagnating. A 24-hour ventilation system that combines natural air supply and mechanical exhaust is installed for air control.

The jury panel of the Good Design Award commented:In addition to the functional concept of being able to operate the device by voice only, the white spherical exterior of the toilet has a significant impact in the midst of public facilities, which tend to be uniformly designed. Users do not necessarily have the knowledge that they can operate the system with just their voice, so if they approach the toilet with an interest in its unique appearance, the experience will further deepen their amazement. The experience will also exceed expectations for international visitors who come to Japan with an image of high technology.
