In 1892, the Hokkaido Colliery and Railway Company opened the from Oiwake to Yà «bari for transporting coal to the Port of Muroran via the Muroran Main Line.
In 1906, the Japanese Government nationalised the company, and double-tracked the line between 1912 and 1919. However, the line was single-tracked in 1932. The abandoned western tunnel north of Shimizusawa, and significant portions of the second line formation are still visible.
The Minami-Chitose - Oiwake and Shin-Yà «bari - Kami-Ochiai Junction (on the Nemuro Main Line) sections opened in 1981, becoming the two ends of the Sekishà  Line. The Yà «bari Line was renamed in two sections, the section between Oiwake and Shin-Yà «bari becoming the mid section of the Sekishà  Line, and the section between Shin-Yà «bari and Yà «bari becoming the Yà «bari Branch Line of the Sekishà  Line. The new line shortened the main route to eastern Hokkaido. Previously, passengers to Shintoku and further east had to travel via the Nemuro Main Line.
In 1985 the Yà «bari station was relocated 1.3 km south of its original location, and it was moved another 800 m south in 1990.

On 27 May 2011, the Super à Âzora 14 service from Kushiro to Sapporo was brought to an emergency stop inside the 685 metre-long No. 1 Niniu Tunnel in Shimukappu, Hokkaidà Â, at around 21:55 after car number 2 of the 6-car formation became derailed. The train caught fire, and all of the 245 people on board, including train staff eventually evacuated the train. 39 were treated for smoke inhalation and minor burn injuries. The burnt-out train was removed from the tunnel on 29 May 2011.
At around 20:50 on 16 February 2012, a freight train derailed at Higashi-Oiwake Station after passing a signal at red and colliding with the wall of a snow shelter adjacent to the station.
The up container freight train from Kushiro Freight Terminal to Sapporo Freight Terminal was normally scheduled to pass Higashi-Oiwake Station non-stop, but on this occasion faced a red signal to allow the delayed down Super à Âzora 13 service to pass in the opposite direction. The driver reportedly applied the brakes, but the train failed to stop and was derailed by the catch points protecting the single-track line, hitting the wall of a snow shelter protecting the junction. The JR Freight Class DF200 diesel locomotive and four of the container wagons in the train were derailed, but the lone 25-year-old driver was uninjured. Six train services were cancelled as a result.
