Pritzker Prize-winning architect Shigeru Ban has designed two public toilets in Tokyo with transparent glass walls that become opaque when they are occupied.
This see-through quality was also selected to reassure users that the facilities are clean without them having to enter the toilet block first to check.
The new buildings replace two dated public toilets in a pair of small parks near the large Yoyogi Park in Shibuya.
Each facility comprises three separate cubicles, a male, female and accessible toilet, which are divided by mirrored walls.
