SuperKEKB and Belle II experiment has started commissioning. The detector is designed with excellent performance of particle identification (PID) for charged particles. While neutral PID is expected to be improved by extending PID to (anti-)neutron. This tool is part of the key point to pursue some physics measurements, such as baryonic decay including (anti-)neutron as final state particle. Multiple variables analysis (MVA) methods will be used. The PID performance based on Monte Carlo simulations and Belle II data will be reported in this talk.
