#3: Nanagō Dōri Park

The Voice-Controlled Orb


Location #3 is at 2-53-5 Hatagaya, Shibuya. It stands at one end of the narrow Nanagō Dōri Park.

Its designer, Kazoo Sato and the Disruption Lab Team, had read studies reporting the high percentage of public toilet users in Europe and the U.S. who modify their behavior to avoid touching surfaces.

They developed the "Hi Toilet" where all controls can be operated by voice. Soon after they got that working, the COVID-19 pandemic arrived and made contact-free public devices even more relevant. The universal toilet in this facility has the voice control system.

Visiting the Toilet

Seen from the sidewalk along the street, the public toilet is a mysterious white orb at the west end of the narrow Nanagō-Dōri Park.

The rear side of the orb is sliced off vertically, with pictograms pointing the way.

The floor plan shows that there's a men's room (which has just urinals and a sink) and a universal toilet.

Looking into the universal toilet, the curved exterior wall is at left. To the left of the toilet controls are the microphone and speaker for the voice control. The ostomate fixture with a large shelf above it is close to the door.

The men's toilet needs no closing door. Yes, you could look in and see someone standing at a urinal, and you would know what they're doing. But that's no cause for a moral panic.

Soft overhead lighting comes on when you enter.

There's a water fountain that also provides water for dogs.
