Abstract: Belle II at the electron-positron collider SuperKEKB is the successor to the Belle experiment. Its design luminosity is 6 · 1035/(cm2s), 40 times the record achieved at KEKB/Belle, at the same center of mass energy in the bottomonium region. Over the next years it is expected to accumulate an integrated luminosity of 50 ab−1, collecting by far the largest sample of B-mesons at electron-positron colliders, together with large numbers of bottomonium and lighter particles. After a commissioning run in 2018 the detector started routine data taking in March 2019. we have collected more than 200 fb-1 statistics so far. In this talk the current status of the detector, current and future running conditions a selection of the present physics results and further physics prospects will be shown.
