JT-60SA is a tokamak upgraded from JT-60U. The maximum plasma current (Ip) is 5.5 MA, the maximum toroidal field (Bt) is 2.2 T and the maximum heating power is 41 MW for 100s. The JT-60SA project a joint project by Europe and Japan, and under the Japanese national program as well. The objective is to support researches on ITER and develop physics and engineering basis towards DEMO reactor. Manufacturing of components has been underway for several years both in Japan and EU. The construction of the machine has been ongoing at the JAEA Naka site since January 2013. The latest status of the construction and development, for example heating and current drive (H and CD) systems, will be presented. Development of the Neutral Beam and Radio Frequency systems for 100s injection leads to steady state injection capability for DEMO. In parallel to the engineering works, research activities in preparation for the JT-60SA experiment have been underway in wide collaboration between Japanese and EU researchers. And the JT-60SA Research Plan has been published and updated periodically. Status of the research collaboration in preparation for the JT-60SA experiments will be reported as well.
