Trains are operated by JR-Central Transport Service Company, or TKJ in short, a wholly owned subsidiary of JR Central.

While TKJ operates the line, the rail facilities belong to its parent company JR Central.

Reference:[6] The line is operated using a fleet of four KiHa 11 single-car diesel multiple unit DMUs.

[1] When the line first opened, services were operated using KiHa 40 series single-car DMUs leased from JR Central.

[8] KiHa 11-201 was withdrawn from Johoku Line services on 23 September 2015, and sold to the Hitachinaka Kaihin Railway.
