The main aims of Phase 2 commissioning were to verify the novel nano-beam collision scheme and achieve the machine luminosity O(10³⁴ cm⁻²s⁻¹). The beam instruments including the bunch-by-bunch feedback and orbit feedback systems, which are central to the beam diagnostics at SuperKEKB, were successfully operated throughout Phase 2. In this talk, we will present the commissioning results focusing on beam diagnostics and show prospects for the final phase of commissioning from next spring.
