Japanese graphic designer Tomohito Ushiro has completed the Hiroo East Park toilet in central Tokyo as the latest addition to the Tokyo Toilet project.
Built within the Hiroo East Park, the toilet features a large light panel that circles through 7.9 billion different light patterns, in a reference to the world's population at the point the project was conceived.

Created to replace a red brick block that was previously on the site, the concrete structure has a glazed rear wall that encloses the light panel.
Ushiro, who is the founder of agency White Design, hopes that the toilet will act as a piece of public art and draw attention to the wider Tokyo Toilet project, which will see 17 toilets designed by leading architects and designers built in central Toyko.
