Abstract: The Belle II/SuperKEKB experiment is an e+e- collider running at the Υ(4S) resonance energy to produce B meson pairs. As an upgrade of the Belle/KEKB experiment, it will start physics data taking from 2018 and with ~40 times luminosity. Its goal is to accumulate 50 ab-1 of e+e- collision data. Now the upgrade of the sub-detector systems is on-going in KEK. The physics program has a wide range of areas, including searches for direct CP violation (CPV), lepton flavour violation and dark matter. The current upgrade status of Belle II and SuperKEKB is reviewed and some physics opportunities at this facility are introduced.

Key words: Belle II, SuperKEKB, e+e- collider, New Physics
