Abstract	At the end of 2018 the inner subdetectors, SVD (Silicon Vertex Detector) and PXD (Pixel Detector) were installed in Belle II. By the end of 2019 Belle II has collected a total of 10 fb−1. With the early data taken the charged-particles tracking performance of the detector was characterized, reconstruction of known resonances and the capability of identifying displaced vertices decays. One of the first benchmarks for B physics was the measurement of the B 0 −B mixing frequency. First results are based on the B mesons semileptonic decay mode. The rediscovery of the “golden mode” B0→J/ψK0S, a CP eigenstate, is shown along other B→[cc¯]Xs decay modes.Prospects for dark sector searches, CPV in Charm physics and other motivations for B physics are discussed.
