History[edit]

Looking from Musashi-Itsukaichi Station towards Musashi-Masuko Station

The Itsukaichi Line was built by the Itsukaichi Railway in 1925. In 1930, all sections (Tachikawa - Haijima - Musashi-Itsukaichi - Musashi-Iwai) were opened. There were two competing railways between Tachikawa and Haijima: the Ōme Electric Railway (now the Ōme Line) and the Itsukaichi Railway. In 1940, the Itsukaichi Railway was taken over by the Nambu Railway, becoming the Nambu Railway Itsukaichi Line. In 1944, Nambu Railway was nationalized and this line became the JGR Itsukaichi Line. At the same time, the section of the line between Tachikawa and Haijima was deemed non-essential and closed. However, the Tachikawa - Musashi-Uenohara and Musahi-Uenohara - Nishi-Tachikawa sections of the former Nambu Railway are still used by Chūō Main Line and Nambu Line trains traveling to and from the southern area of Tachikawa Station.
