Abstract	The rate of semitauonic 𝐵 decays has been consistently above theory expectations since these decays were first measured. Recently significant differences between the forward-backward asymmetry in 𝐵→𝐷∗𝑒𝜈 and 𝐵→𝐷∗𝜇𝜈 were also reported. Belle II data is well suited to probe such 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 measurements of semileptonic 𝐵 decays. This talk presents recent Belle II results on lepton flavor universality tests based on inclusive decays.
