Abstract The observed rate of semitauonic B decays has been consistently above expectations since these decays were first measured. Significant differences between the forward-backward asymmetry in B->D*enu and B->D*munu were also reported. Belle II data are well suited to probe these anomalies. The low-background collision environment along with the possibility of partially or fully reconstructing one of the two B mesons in the event offer high precision. This talk presents recent Belle II results on lepton-flavor universality tests.
