Abstract
The Belle II experiment is a substantial upgrade of the Belle detector and will operate at the SuperKEKB energy-asymmetric $e^+ e^-$ collider. The design luminosity of SuperKEKB is $8 \times 10^{35} cm^{-2}s^{-1}$ and the Belle II experiment aims to record 50~$ab^{-1}$ of data, a factor of 50 more than the Belle experiment. With this amount of data, decays sensitive to physics beyond the Standard Model can be studied with unprecedented precision. In this contribution we will present our prospects for studying lepton flavor non-universality with the modes $B \to D^{(\ast)} \tau \nu$ and for the measurement of the CKM parameter $|V_{ub}|$.
