Japan Atomic Energy Agency is in charge of procurement of Toroidal Field (TF) coil and conductors for International Thermonuclear Experimental Reactor(ITER) as a domestic agency of ITER in Japan. The TF conductor is composed of cable using 900 superconducting strands and 522 copper strands with a diameter of 0.8mm sheathed in the jacket with a thickness of 2mm and outer diameter of 43.7mm and the maximum length is 760m. The procurement of conductor was started from 2008 and preparations of strands, cabling, jacket and jacketing facility have progressed under the cooperation from industries. As a result, preparation to manufacture conductor is completed. First of all, to demonstrate the manufacturing procedure, 760m long dummy conductor has been manufactured and successfully completed. Based on the achievement, Japan started to make superconducting conductor. In the conference, status of procurement of TF conductor and conductor manufacturing technologies are introduced.
