Abstract: The Belle II experiment at the SuperKEKB accelerator is the upgraded successor of the $B$-factory, the Belle experiment and KEKB accelerator. The instantaneous luminosity is designed to 6 $\times$ 10$^{35}$ cm$^{-2}$s$^{-1}$ which is 30 $\times$ higher than the KEKB. We aim to accumulate 50 ab$^{-1}$ in the 2030 to discover a new physics beyond the Standard Model. The current integrated luminosity has reached 213 fb{-1} in summer 2021. The Belle II can also provide various physics subjects: beauty, charm, $\tau$-lepton, dark sector and hadron physics and etc. We confirm the detector performance as expected. Several physics results with leading precision have already been appeared. We briefly report the status and the prospect of the Belle II experiment.
