SuperFGD, a highly granular scintillator detector, is under final stage of construction to reduce systematic uncertainties in the T2K experiment in order to improve the sensitivity to CP-violation in neutrino oscillations. SuperFGD will be comprised of about 2×106 small (10×10×10 mm3) optically isolated polystyrene based plastic scintillator cubes with three orthogonal holes 1.5 mm in diameter. The readout of scintillating light from each cube is provided by three wavelength shifting fibers inserted into the three holes and coupled to Hamamatsu MPPC. The results of the study of scintillation elements of the SuperFGD detector, the results of charged particle beam tests at CERN of two prototypes of SuperFGD detector and plans for the final assembly of the detector and its installation at the experimental site are presented in this paper.
