Abstract: The Belle II experiment is a substantial upgrade of the Belle detector that will operate at the SuperKEKB energy-asymmetric e+ e− collider. Belle II is preparing to start recording collisions at the Υ (4S) energy in 2018 and collect 50 ab−1 of data by 2025, a factor of 50 more than the Belle experiment. In particular we report prospects for measuring the Cabibbo- Kobayashi-Maskawa angle φ3(γ) and observables in semileptonic B meson decays associated with the unitary matrix element Vub.
