Haru-no-Ogawa Community Park Toilet

The transparent Tokyo toilet

There are two things we worry about when entering a public toilet, especially those located at a park. The first is cleanliness, and the second is whether anyone is inside. Using the latest technology, the exterior glass turns opaque when locked. This allows users to check the cleanliness and whether anyone is using the toilet from the outside. At night, the facility lights up the park like a beautiful lantern.
