History
Nagashima Dam Station opened on 2 October 1990 on a newly built section of the Ōigawa Railway Ikawa Line, after a portion of the original route was relocated to avoid the reservoir created by the completion of the Nagashima Dam. The station sits 11.4 kilometres from the line's official starting point at Senzu, in the town of Kawanehon in Shizuoka Prefecture. Between Abt Ichishiro Station and Nagashima Dam the gradient reaches 90 per mille, requiring an Abt rack-and-pinion system; this is the only such operation in Japan today. Two opposed side platforms serve a small red-roofed unattended station building accessed by a level crossing, with a stabling siding for the Abt-system electric locomotives on the Senzu side.

Notes
The old tunnels of the pre-1990 route between Nagashima Dam and Abt Ichishiro have been turned into an unlit walking path nicknamed the "Mystery Tunnel", for which torches can be borrowed at the nearby visitor centre.
