Recent research progress on JT-60U in advanced steady-state operation is presented. High fusion performance of 
has been obtained in negative magnetic shear plasmas as well as in high- H-mode. A negative shear discharge is shown to have enhanced core confinement. Its sustainment and compatibility with radiative divertor are also explored. Stability and confinement are improved in high triangularity operation and a noninductive discharge with high integrated performance has been achieved. The installation of negative-ion-based neutral beam injection system on JT-60U has been completed and beam injection into plasmas has been started. A preparation for the modification of the present JT-60U's open divertor to a W-shaped semi-closed divertor, and a conceptual design and R&D for JT-60 Super Upgrade are in pregress.

The negative triangular plasma is proposed as one of methods for the heat load solution in the magnetic confinement fusion. The ST is easier to implement negative triangular plasma and we discuss such a possibility.

While negative triangular tokamak configuration has possibility to improve power handling capability, mechanism of improved confinement observed in TCV is still not fully understood. In this talk, we will summarize present understanding of linear eigenmode structure of toroidal drift waves and also flow shear suppression of turbulence.

We are proposing negative triangularity tokamak (NTT) for drastic improvement of power handling capability of tokamak fusion reactor. This configuration is magnetic hill but we found it is stable up to a normalized beta 3.2 with appropriate profile control to increase magnetic shear near periphery. MHD stability of single null divertor also shows a normalized beta 
3 can be stable. This leads to a possible implementation of flux tube expansion (FTE) divertor proposed by Takizuka and may get 2.7 flux expansion.
