Belle II is designed to operate at a peak luminosity of $8\times 10^{35} cm^{-2}s^{-1}$ with a target integrated luminosity of 50 $ab^{-1}$, a factor of 50 more than the BELLE experiment. This will allow studies of B meson decays, along with charm,τ and many other physics topics, with unprecedent precision in the clean $e^+e^-$ collider environment. In this paper the Belle II experiment is described, with its planned physics program and prospects. 000001546 8560_ $$fclaudia.cecchi@desy.de 000001546 8564_ $$uhttps://docs.belle2.org/record/1546/files/Cecchi-v3.pdf
