The JT-60SA project is conducted under the BA satellite tokamak programme by EU and Japan, and the Japanese national programme. The project mission is to contribute to early realization of fusion energy by supporting ITER and by complementing ITER with resolving key physics and engineering issues for DEMO reactors. In this paper, the assembly of major tokamak components such as VV and TFC is mainly described. An assembly frame (with the dedicated cranes), which is located around the tokamak, is adopted to carry out the assembly of major tokamak components in the torus hall independently of the facility cranes for preparations such as pre-assembly in the assembly hall. The assembly frame also provides assembly tools and jigs to support temporarily the components as well as to adjust the components in final positions.
