The Fujikoshi Line (不二越線 Fujikoshi-sen?) is a Japanese railway line which connects Inarimachi Station with Minami-Toyama Station all within Toyama, Toyama Prefecture. It is owned and run by Toyama Chihō Railway. This line and the Toyama Chihō Railway Kamidaki Line are operated as a single line.
The Toyama Light Railway Co. opened the Toyama - Sasazu (since closed) line in 1914. The company merged with the Toyama Electric Railway Co. in 1941, and the Inarimachi - Minami-Toyama section was electrified at 1500 VDC two years later when the current company was formed by a merger of all non-government owned railways in the Toyama area.
