Hands-on experience at one of Tokyo’s more unique museums

Located in the Odaiba–Ariake area, the museum is run by the Tokyo Metropolitan Government Bureau of Sewerage. Here you can learn about the surprisingly fascinating world of Japan’s sewerage system by exploring the museum’s exhibits and experiencing first-hand what goes into keeping the city clean.

Put yourself in the shoes of a sewerage worker by manning sewerage pumps and accessing the underground pipes, before heading to the central control room and water analysis laboratories to learn the science behind the systems. The experience will leave you with a newfound appreciation for the city’s sewerage workers. Suitable for the whole family, admission to the museum and its activities are free.
