Inokashira Pond lies at the center of Inokashira Park and is the source of the Kanda River. It is Y-shaped and made up of three parts: Ochanomizu Pond, Benten Pond, and Boat Pond.

In the Edo period, the pond served as the water source of the Kanda Josui, the water supply for Edo (now Tokyo). Since 2014, the park has carried out "kaibori", in which the pond water is drained to remove invasive species and for other work.
