A highly granular scintillator detector SuperFGD is under 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 2x10^6 of optically isolated small (10x10x10 mm^3) polystyrene based plastic scintillator cubes with three orthogonal holes of 1.5 mm in diameter. The readout of scintillating light from each cube is provided by three wavelength shifting fibers inserted into three holes and coupled to micropixel photosensors MPPC’s. Cubes are covered by a white chemical reflector for optical isolation. The technology of making these cubes and their mechanical properties will be reported. Obtained main characteristics with cosmic muons, temperature tests, and a method of the assembly a large segmented detector will be presented
