The route name is derived the line's route on the east shore of Kamo River. It is constructed under Kawabata Street along the Kamo River as an underground extension of the Keihan Main Line. The line is only 2.3 km long but serves as an important transport corridor in central Kyoto.

To recover the cost of construction and interest payments (69 billion yen) of the line, a surcharge of 60 yen is added on top of regular fares when a trip uses the line. The recovery rate at the end of FY2016 was 31.8%; most of it recovered by the 60 yen surcharge. It is undecided whether the additional surcharge will be imposed indefinitely.[4]

The Temmabashi to Kiyomizu-Gojo section opened as dual track, electrified at 1,500 V DC, in 1910, and was extended to Sanjo in 1915. The Temmabashi to Yodoyabashi section opened in 1963.

The line was built and opened by an independent railway company, Shigi-Ikoma Electric Railway (信貴生駒電鉄, Shigi Ikoma Dentetsu) in 1929. The company aimed to build a line to connect its main line, the present-day Ikoma Line, but cancelled the plan for financial reasons, and transferred the operation to Keihan. The operator was renamed Katano Electric Railway (交野電気鉄道, Katano Denki Tetsudō) in 1939, Keihanshin Express Electric Railway (京阪神急行電鉄, Keihanshin Kyūkō Dentetsu) in May 1945, and Keihan Electric Railway on 1 December 1949.[2]
