The high luminosity e+e−collisions at the SuperKEKB accelerator produce heavy flavor particles, the B and D mesons as well as the τ lepton, at the rate of about 1010 particles/year with the designed luminosity of 8×1035 cm−2 s−1. These high statistics data provide rich physics programs at the Belle II experiment, to search for new phenomena beyond the Standard Model of particle physics. I present the physics program, recent status and prospect of the Belle II experiment.
