Location
History
Tamagawa-Jōsui Station opened on 15 May 1950 as the terminus of the Seibu Railway's Jōsui Line, which Seibu had created by acquiring a former Hitachi Aircraft Tachikawa-plant siding from Nikko Industries in 1949. The line was renamed the Haijima Line and extended west to Haijima on 15 May 1968, turning Tamagawa-Jōsui into a through stop. On 10 December 1989 the layout was rebuilt as a two-island, three-track station, and the Tama Toshi Monorail platforms opened on 27 November 1998. Concurrent works moved the Seibu platforms, elevated the concourse, opened a new walkway, and removed the previous level crossing. An enclosed waiting room was added on the Haijima Line side in November 2007.
Notes
The original station building still stands south of the present concourse: the 1989 structure was retained when the line was elevated in 1998, with its old ticket-window area shuttered and its former entrance plaza converted into a bicycle parking lot.
