In 2020, the non-profit NIPPON foundation began commissioning public toilets in Tokyo’s Shibuya district. The result – known as the Tokyo Toilet Trail – is a Camino de Santiago for the design obsessive.

At Ebisu station, a glimmering pavilion with a ribbon-like roofline by Pritzker-winning architect Fumihiko Maki marks the start of a trek that winds its way north through the Shibuya ward. It stops by Tadao Ando (a gleaming, truncated cone), Shigeru Ban (translucent, coloured glass boxes that turn opaque when occupied) and a forest of white-tiled mushroom-esque structures designed by Toyo Ito.
