Tokyo Sewerage Museum “Rainbow”

Tokyo Sewerage Museum “Rainbow” is a public relations facility for sewerage operated by the Bureau of Sewerage Tokyo Metropolitan Government.
The museum was opened as the Tokyo Sewerage Museum “Rainbow” in the Ariake Water Reclamation Center in Koto-ku, Tokyo in 1997.
In 2013, the museum was reopened after a total renovation involving reproductions of a life-size sewer pipe and water reclamation center. It actively advertises the roles and interesting features of Tokyo’s sewerage system.
