000001546 520__ $$aThe Belle II experiment, a substantial upgrade of the BELLE detector operating at the SuperKEKB energy-asymmetric $e^+ e^-$ collider,  has recently restarted its data taking with the so called "Phase 3" run at the $\Upsilon(4S)$ resonance.  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.
