Final Design Report of the ITER Engineering Design Activities has been approved by the ITER Council with completion of the initially planned six years period. One of the main activities was the implementation of the technology R&D to provide data-base for, and to demonstrate technological feasibility of the ITER design. Most of the initially planned R&D tasks have been performed. In this review paper, we report on the achievements of the ITER technology R&D carried out during the Engineering Design Activities by the Japanese Home Team. The three Parties except US are developing necessary framework for three years extension to implement site adaptation studies as well as residual system tests of the ITER technology R&D.
