History
Nakasato Station opened on 8 August 1915 as the Nakasato halt on the Saku Railway, accompanying the new Komoro–Koumi service across what is now the city of Saku, Nagano Prefecture. The Saku Railway was nationalised on 1 September 1934 and absorbed into the Rail Ministry's Koumi-Hoku (later Koumi) Line, at which point the stop was promoted from a halt to a full station. Through-passenger service was initially limited to stations on the Shin'etsu Main Line and was lifted on 1 December 1954. With the privatisation of Japanese National Railways on 1 April 1987 the station came under JR East. It remains an unstaffed single-side-platform stop with a waiting room on the platform.

Notes
When the station opened in 1915 it was a halt with severely limited through-ticket service — only local Saku Railway stops and the three Shin'etsu Main Line stations of Komoro, Ueda, and Nagano — and the restriction was not fully lifted until 1954.
