TOKYO, Japan — Tokyo now offers a new way to experience nature's call in the form of transparent high-tech public toilets.
The stalls are colorful, spacious, and available at a public park, but the only catch is, their walls remain transparent until toilet-goers literally lock the door.
When the restroom is occupied and locked, the toilet walls, made from smart glass, suddenly turn opaque, providing lasting privacy as long as the door remains locked.
The toilets were installed at two parks in Tokyo as part of the "Tokyo Toilet Project" which aims to reinvent public toilets as cleaner and safer facilities.
For years, the restroom at Sloan's ice cream shop on Clematis Street in West Palm Beach has featured the same type of door.
