Nanagō-Dōri Park Public Toilet
Designer: Kazoo Sato (Creative director, born in 1973. After working with Sony Music Entertainment and Leo Burnett, he joined TBWA\HAKUHODO in 2010. In addition to his advertising work, he has directed art for music videos and concerts.)
This project set out to create one of the world’s cleanest public toilets, branded as the “Hi Toilet.” It incorporates voice-command, hands-free technology, and a 24-hour ventilation system that combines natural airflow with mechanical exhaust. Fresh air is drawn in from the base of the exterior wall and released through the spherical dome ceiling via a fan installed behind the sanitary equipment.
