The Belle II experiment has collected 427/fb of data from e+e– collisions produced by the asymmetric-energy SuperKEKB collider. Three-quarters of the data is collected at the center-of-mass energy of Y(4S) resonance, which decays to B-meson pairs. For these data, we have made measurements of rare B decays, isospin asymmetry, and CP violation, as well as searches for lepton-flavor-universality violation. The talk highlights include the first observation of 𝐵→𝐾𝜈𝜈¯ and measurements of lepton-flavor-universality in the semitauonic B decays.
