This scenic road was built alongside the Tamagawajosui (Tama River water supply channel). When wells and streams could no longer meet old Edo’s demand for drinking water due to an increased population, the Edo shogunate devised a plan to bring in water from the Tama River. The water supply channel is said to have been completed in 1653 by the brothers Shoemon and Seiemon Tama, and it has been known as the Tama River water supply channel ever since.

The channel runs 43 kilometers from its intake at Hamura on the Tama River to the Yotsuya Okido gate. As the elevation difference between those points is small, getting the water to flow well was a very difficult task. The area downstream from Miyamoto Bridge was designated as a historical and environmental preservation area by the Tokyo Metropolitan Government in 1999. Additionally, the area downstream from the Hamura water intake was designated as a national historical landmark in 2003.

Currently, the area open as the Tamajosui Scenic Road is a about 24 kilometer area from Asama Bridge in Suginami-ku to Heiwa Bridge in Fussa. Visitors can also walk further upstream to get a view of what the channel was originally like.
