The Belle II experiment at the SuperKEKB energy-asymmetric $e^+ e^-$ collider is a substantial upgrade of the B factory facility at the Japanese KEK laboratory. The design luminosity of the machine is $8\times 10^{35}$ cm$^{-2}$s$^{-1}$ and the Belle II experiment aims to record 50 ab$^{-1}$ of data, a factor of 50 more than its predecessor. Recent results from the study of first physics runs in 2018-2020, around 100 fb$^{-1}$ of data, will be shown. One of the highlights is about the contribution from the Taiwan team on the anti-neutron tagging method with related observations. Prospects of the Belle II experiment and physics outcomes will also be discussed.
