Kuji Valley (久慈渓流/久慈川渓谷, kuji-keiryu/kujigawa-keikoku) is located along the upper reach of the river. It has a water spring named Furosen (不老泉, literally "ageless spring"), which is known for one of the valuable water springs in Iwate. Water from the spring was initially utilized for placer gold mining in Meiji Era. Later in the Taisho Era it was named after a legend, in which one had become immortal after drinking the water. The valley is a part of Kuji-Hiraniwa Prefectural Natural Park.[2][3][4]
Kuji Region used to contain characteristic Tatara furnaces, in which a water wheel was utilized to supply the air to the furnace, while in many other regions of the country man-power was utilized. Today some parts of the furnaces remain along a tributary river of Kuji River.[5]
The tributaries consist of Natsui River (夏井川), Nagauchi River (長内川), Sawa River (沢川), Tazawa River (田沢川), Tagonai River (田子内川), Heromachi River (戸呂町川), Hinosawa River (日野沢川), Enbetsu River (遠別川) and Futamata River (二又川).[1]
Taki Dam (滝ダム) is a concrete gravity dam situated on Nagauchi River, which is one of the tributaries. It has the total capacity of 7,600,000 m3 (9,900,000 cu yd) and the height of 70 m (230 ft). Construction of the dam started in 1969 and was completed in 1982.[6]
