Tours of revamped public restrooms in Tokyo's Shibuya Ward were launched earlier this month to dispel the traditional perception of the facilities as being dirty and smelly.

A total of 17 public restrooms have been redesigned by notable architects under The Tokyo Toilet project, turning the often neglected spaces to safer and more fashionable structures.

"Many people who join the tour are interested in architecture," said Yumiko Nishi, PR manager of the ward's tourism association, which organizes the tours via shuttle minivan.
