In the capital of Japan, in the heart of the megalopolis, in the Shibuya district, glass toilet stalls were installed, which were designed by Shigeru Ban, winner of the most prestigious architectural Pritzker Prize.

These bright glass structures of different colours look unusual and are even compared to the abstractions of Piet Mondrian.

The walls of the toilets are transparent. But only when no one’s inside. This is convenient because you don’t have to go inside to make sure the toilet is free. As soon as the glass door is locked from the inside, the walls become matte.

This effect is achieved by the unique transparent tape. When there is no one in the toilet, electricity is supplied to the film and it lets in light. If the stall is closed from the inside, this function is blocked and the walls become matte.

All the toilets are divided into three zones: male, female and disabled. The room has a toilet, a sink and a small table.
