Transparent toilets: Designed by Shigeru Ban Architects, a Pritzker Prize-winning architecture firm, two new sets of transparent toilets have been installed in two Tokyo parks.

High-tech toilets: Once a user enters the toilet and locks the door, the walls will turn opaque to provide privacy.

No more guessing: The Tokyo-based architecture firm says the design is aimed at tackling two concerns that may deter people from using public toilets: "The first is cleanliness, and the second is whether anyone is inside."

Tokyo Toilet Project: The two sets of transparent toilets, located in Tokyo's Shibuya district, are a part of the newly launched Tokyo Toilet Project.

Public toilets re-imagined: Founded by the Nippon Foundation, a private, non-profit charity that focuses on social innovation, the Tokyo Toilet Project has partnered with some of the biggest names in the architecture and creative industries including Tadao Ando and Toyo Ito to create 17 new public toilet facilities in Shibuya.

"Modern Kawaya": Among the new facilities is Modern Kawaya, which translates to "river hut" and is also the original word for toilet in Japanese. It was designed by FRAME Award-winning Masamichi Katayama and his interior design studio Wonderwall Inc.
