Welcome to the Tokyo Waterworks Historical Museum

The Tokyo Waterworks Historical Museum, run by the Tokyo Metropolitan Waterworks Bureau, interprets unique stories of water supply system of Tokyo Waterworks.

The history of Tokyo Waterworks can be traced back to the early 17C when Ieyasu Tokugawa founded shogunate at Edo (present-day Tokyo).
The waterworks in the Edo Era was called “Josui” (clean water) which the water was guided through conduits made of stone or wood to the clean water well, where people drew the water for drinking and daily use.

Due to contamination of the channels and decay of wooden conduits, demand for the construction of modern waterworks had grown in the late of 19C.
In 1898, Tokyo Waterworks started to supply water from the Yodobashi Purification Plant.
Since then, Tokyo Waterworks have been promoting measures to secure water resources and improve facilities in order to provide a constant and stable supply of clean water.
