History
Naka-Karuizawa Station opened on 15 July 1910 as Kutsukake Station on the Imperial Government Railways' Shin'etsu Line, and was renamed Naka-Karuizawa on 10 April 1956. After JNR privatisation in 1987 the station passed to JR East, then to the third-sector Shinano Railway on 1 October 1997 when the Hokuriku Shinkansen Takasaki–Nagano section opened. The current elevated station building, integrated with the Karuizawa-town community facility "Kutsukake Terrace," entered service on 20 July 2012. Suica IC-card service began on 14 March 2026, the same day the staffed window closed and the station became unmanned.

Notes
The station building is integrated with "Kutsukake Terrace," a Karuizawa town facility that houses the municipal Naka-Karuizawa Library — a rare case of a public library sharing a station concourse.
