In a project launched by the Nippon Foundation, 16 well-known architects were asked to renovate 17 public toilets located in the public parks of Shibuya, Tokyo. Shigeru Ban designed restrooms that are surrounded by transparent tinted glass, which allows a person to evaluate the interior before entering. In August 2020, these restrooms were installed in Haru-no-Ogawa Community Park and the Yoyogi Fukamachi Mini Park.
