The designer aimed to achieve this by surrounding the facility with white aluminium louvres.
“Since the toilet, located beside the police box in front of the Ebisu station, is a neighborhood symbol that people see every day, we thought it should not be too conspicuous,” explained Sato.
“The aluminium louvres give a bright and light impression, and we have tried to create a quiet appearance that blends naturally with the cityscape.”
The louvres are separated with two-centimetre gaps to create a permeable wall that has an open space at its base.
The wall encloses a light-filled corridor that runs in a U-shape around the rectangular block with the entrances at each end. Inside the block are five toilet cubicles that are not divided by gender.
“The facility should be easy to enter, easy to use, and have a clean appearance that inspires the passersby to feel a little bit brighter and fresher,” Sato continued.
“This pure white toilet was designed by addressing every point of consideration that is usually taken for granted in a restroom facility.”
Along with the block, Sato also designed the pictograms that are used to depict the various facilities.
These pictograms are being used on all of the facilities built as part of the Tokyo Toilet project.
In total, 17 toilets are planned as part of the Nippon Foundation‘s Tokyo Toilet project.
Blocks completed so far include a trio of mushroom-like blocks designed by Toyo Ito, a pair of transparent blocks designed by Shigeru Ban and a house-shaped public toilet by fashion designer Nigo.
