Transparent Public Toilets Unveiled In Tokyo Parks — But They Also Offer Privacy

The idea of using a public bathroom with see-through walls may sound like the stuff of nightmares. But a famous Japanese architect is hoping to change that view, using vibrant colors and new technology to make restrooms in Tokyo parks more inviting.

"There are two things we worry about when entering a public restroom, especially those located at a park," according to architect Shigeru Ban's firm. "The first is cleanliness, and the second is whether anyone is inside."

Transparent walls can address both of those worries, Ban says, by showing people what awaits them inside. After users enter the restroom and lock the door, the powder room's walls turn a powdery pastel shade — and are no longer see-through.

"Using a new technology, we made the outer walls with glass that becomes opaque when the lock is closed, so that a person can check inside before entering," the Nippon Foundation says.

The group is behind the Tokyo Toilet project, enlisting world-famous architects to create toilets "like you've never seen."
