- Japanese: 堀川 (horikawa)
The river is today sunken and partially covered. It is flanked on both sides by the road known as Horikawa-dôri, which was originally known as Horikawa-kôji when it was built in the Heian period. Many lumber merchants, including some who transported lumber up to Kyoto from Tamba province along the Katsuragawa, resided in one area alongside the river.
