Integrated modeling on areas of plasma core, edge-pedestal and scrape-off-layer (SOL)-divertor progressed based on the researches in JT-60U experiments. In the core plasma, an anomalous transport model of fast particles due to the Alfv$'e$n eigenmode is proposed, and a new one-dimensional core transport code, which can describe the radial electric field and plasma rotations, self-consistently, is developed. The integrated code TOPICS-IB is improved in the edge pedestal region, and effects of the pressure profile inside the pedestal and the collisionality dependence on the ELM energy loss are clarified. The impurity Monte Carlo code is incorporated to the integrated divertor code SONIC. Simulation of impurity behavior at X-point MARFE successfully produced the complete detached plasma, where a part of sputtered carbon penetrates into the main plasma and contributes to the enhanced radiation near the X-point.
