Recent progress in development of high performance plasma and efforts to prolong their sustainment towards ITER advanced operations and a steady-state reactor in JT-60U are presented focusing following achievements; N=3 sustained for 6.2s (4.1tR) without NTMs in normal shear, fBS0.45 sustained for 5.8s (2.8tR) under nearly full CD in weak a shear plasma, fBS0.75 sustained for 7.4s (2.7tR) under nearly full CD in a reversed shear plasma. Furthermore, importance of these results and issues in advanced tokamak development will be discussed.
