The beam collision with 3mm vertical beta function at the interaction point is confirmed during prior beam commissioning until July 2018. The next beam commissioning with the inner silicon vertex detectors so called "phase-3 commissioning" will start in March 2019. In the early part of next phase-3 commissioning, we plan to try the collision operation with over 1A stored beam current in order to exceed 1 x 10³⁴ cm⁻² s⁻¹ luminosity. We will report the preliminary results of the early stage of the SuperKEKB phase-3 commissioning.
