Theory and simulation researches/educations on turbulence phenomena in high-temperature magnetized plasmas are conducted. Large-scale supercomputer simulations based on the five dimensional gyrokinetic theory investigate micro-instability (ITG, TEM, ETG, KBM, etc) driven turbulent transport processes in toroidal plasmas. Quantitative comparisons with experimental measurements in helical and tokamak devices and the predictions for the future burning plasmas are carried out. Also, fundamental physics on the self-generated zonal flows and their nonlinear interactions with turbulent vortices in kinetic plasma turbulence is explored.
