Recent results from JT-60U on high performance experiments and studies on steady state plasma are presented. High fusion performance of s keV, , , = 40 keV has been obtained in the regime named ''high- H-mode''. By intensive survey on pressure/current profile control, beta limit has been substantially expanded: , 4.0%mT/MA. As a result, up to 10 seconds of quasi steady state high confinement discharges, with a substantiall bootstrap current fraction, have been experimentally demonstrated. Up to 3.6 MA of plasma current has been driven by LHCD. In low current ( 1.2 MA), full non-inductive current drive has also been achieved by NB and NB+LHCD.
