Shinonoi

Departure data for this station is not available on this site.

Shinonoi Station opened as a station of the Government-operated Shin'etsu Line on 15 August 1888, with revenue service starting on 15 September the same year. On 1 November 1900 the Chūō Line (later renamed the Shinonoi Line) opened from the station as far as Nishijō. A second-generation station building was completed in January 1927 and a third-generation building in April 1982. With the privatisation of JNR on 1 April 1987 the station passed to JR East. A fourth-generation overhead station building and east-west pedestrian concourse opened on 14 September 1995. Following the partial opening of the Hokuriku Shinkansen on 1 October 1997, the Karuizawa–Shinonoi section of the Shin'etsu Main Line was hived off to Shinano Railway, and the station became a joint JR East / Shinano Railway facility from that date. From 15 March 2025 Suica became usable on the JR side; Shinano Railway followed on 14 March 2026.

Between March 1990 and July 1991 the station's departure jingle was a brass fanfare, prompted by the then-stationmaster's idea (initially inspired by the nearby Chausuyama Dinosaur Park) that morphed into an Olympic-style fanfare while Nagano was bidding to host the 1998 Winter Games. Each of the three platforms had its own piece (No. 1 performed by the Nagano City Fire Brigade, Nos. 2 and 3 by the Japan Ground Self-Defense Force), but the fanfare proved deeply unpopular with regular commuters and was discontinued once the Nagano Olympics bid succeeded on 15 June 1991.
