    At present, the ITER Organization undertakes the design, construction, operation, decommissioning, etc. of equipment/facilities of ITER(International Thermonuclear Experimental Reactor), while seven participants handle the manufacturing under an adopted "in-kind system": in addition, equipment/facility manufacturing is under way. Japan has been assigned to develop a part of the divertor systems, plasma heating systems, plasma diagnostics, and other important items including Toroidal Field (TF) coils to generate a magnetic field for plasma confinement and Mitsubishi Heavy Industries, Ltd. (MHI) is involved in nearly all of these. This paper reports on the results as well as the present status of verification tests, etc. for the manufacturing of actual TF coils and briefly explains our activities for the divertor systems indispensable for sustaining stable plasma confinement.
