During the day, service operates at approximately 30 minute intervals. In addition to trains running between Tajimi and Mino-Ōta Stations, there are also trains that enter the Takayama Main Line and run through to Gifu Station. During weekday morning and evening rush hours and on Saturday mornings, a train serves commuters by going to Nagoya Station.
The line traces its origin to the Tōnō (Eastern Mino) line, an 11.9 km (7.4 mi), 762 mm (2 ft 6 in) gauge railway that opened in 1918. The section from Shin-Tajimi to Hiromi Station was nationalized in 1926, named the Taita Line, and regauged to 1,067 mm (3 ft 6 in), and extended to Mino-Ōta in 1928.
Passenger trains were replaced by DMUs in 1934, and steam locomotives ceased operating on the line in 1969. From 1 April 1987, with the privatization and division of the Japanese National Railways (JNR) into regional companies, the Taita Line became part of JR Central.
