History
Tatsuno Station opened on 11 June 1906 with the extension of the Imperial Railways line between Okaya and Shiojiri, the original Chūō Main Line route. The Ina Electric Tramway, predecessor of the Iida Line, reached the station from the west in 1916, and was nationalised as the Iida Line in 1943. The station prospered as the transfer point between the two lines, but the opening in 1983 of the Shiōjine Tunnel short-cut between Okaya and Shiojiri routed Chūō Main Line express trains around Tatsuno; in compensation the current "Luciole Tatsuno" station-building complex was completed on 15 June 1983. With the privatisation of JNR on 1 April 1987 the station became a joint JR East, JR Central and JR Freight facility.

Notes
Tatsuno is the boundary station between JR East and JR Central — although the building and platforms belong to JR East, the actual company boundary lies about 600 metres south on the Iida Line, and on Iida Line trains the crew change is always performed here.
