Hayakawa River

This river flows from Lake Ashi down through Hakone to Sagami Bay and the Pacific Ocean.

The source of this river would seem to be the large lake in central Hakone, but it is mainly fed by groundwater and smaller rivers flowing down the Hakone mountains. The flow rate increases as it flows down the river and derives its name from the Japanese word haya, meaning fast. The Hayakawa River is 20.5 kilometers long from its source near Lake Ashi to its mouth at Odawara City, and flows down at an elevation of 723 meters.
