It is planned to accumulate an e+ e collision data set of 50 ab1, about 50 times larger than that of the earlier Belle experiment. The software library for the new detector will use GEANT4 for Monte Carlo simulation and is an entirely new software and reconstruction system based on modern computing tools. Examples of physics simulation including beam background overlays will be described. 000000533 8560_ $$fkooktae.kim@desy.de 000000533 8564_ $$uhttps://docs.belle2.org/record/533/files/BELLE2-CONF-PROC-2017-018.pdf
