The Belle II experiment at the SuperKEKB energy-asymmetric $e^{+}e^{-}$ collider is a substantial upgrade of the B factory facility at the Japanese KEK laboratory. The design luminosity of the machine is $8\times10^{35}\: cm^{-2}s^{-1}$ and the Belle II experiment aims to record $50\:ab^{-1}$ of data, a factor of 50 more than its predecessor. With this data set, Belle II will be able to measure the elements of the Cabibbo-Kobayashi-Maskawa matrix with unprecedented precision and explore flavor physics with $B$ and $D$ mesons, as well as $\tau$ leptons. Belle II also has a unique capability to search for low-mass dark matter and low-mass mediators. Commissioning operations with the full detector, called "Phase 3 run", started in March 2019 and recorded a data sample corresponding to an integrated luminosity of $6.49\:fb^{-1}$ until June 2019. Here, we report the status of the Belle II detector, the results from the early data, and the prospects for the study of rare decays sensitive to New Physics
