The Belle II experiment at the SuperKEKB energy-asymmetric collider is a substantial upgrade of the B factory facility at the Japanese KEK laboratory. The design luminosity of the machine is cms and the Belle II experiment aims to record 50 ab of data, a factor of 50 more than its predecessor. With this data set, Belle II will be able to measure the Cabibbo-Kobayashi-Maskawa (CKM) matrix, the matrix elements and their phases, with unprecedented precision and explore flavor physics with and charmed mesons, and leptons. Belle II has also a unique capability to search for low mass dark matter and low mass mediators. We also expect exciting results in quarkonium physics with Belle II. In this presentation, we will review the status of the Belle II detector, the results of the planned measurements with data collected in 2019, and the prospects for physics at Belle II.
