Hi Toilet - a “contactless” toilet

My inspiration to design a fully voice activated toilet came about after much research and reading around users' behaviours in public toilets across Europe and the US to avoid contact with the surface; 60% stepping on toilet levers to flush, 50% opening the door with toilet paper, 40% closing the door with hip, 30% avoiding hand-contact as much as possible by using elbow.

After three years of research, planning and designing, we came up with the concept of the VOICE COMMAND Toilet, “Hi Toilet” where all commands were activated by voice. This idea has been in place long before the arrival of COVID-19, but COVID accelerated the acceptance of this unique user experience in terms of “toilets being contactless”. If this toilet could deliver a “Clean City Tokyo” image to the world, I would be extremely happy.

Public toilets must stand the test of time. In addition to our focus on designing impressive facilities, we at THE TOKYO TOILET believe that providing a comfortable user experience through cleaning and maintenance is equally important. The Nippon Foundation, the Shibuya City Government and the Shibuya Tourism Association will work together to maintain these facilities. We will also work with professional toilet inspectors to periodically survey the toilets to ensure we are providing the best user experience.
