Construction of ITER remote experimentation centre (REC) based on the broader approach (BA) activity of the joint program of Japan and Europe is progressed. In order to make the future experiments of ITER and the Satellite Tokamak (JT-60SA) effectively and efficiently implemented, development of a remote experiment system by using JT-60SA was planned and the development of software for the remote experiment was progressed including the systems for the remote connection and the communication between the remote site and the on-site facility. The network system from REC in Rokkasho-site of Japan to the network in EU is established in collaboration with National Institute of Informatics. Effective data transfer method that is capable of fast transfer with the speed in the gigabit range is investigated. Data transfer at the rate of several Gbps was successfully obtained between the institutes in Japan. The preliminary versions of the software for data analysis are developed, such as for visualization of time dependent data and visualization of plasma boundary and spatial profiles of diagnostic data.
