000000509 520__ $$aA next generation B factory and the detector counterpart, SuperKEKB and Belle II, are being built in J apan, as the  upgrades  of  KEKB  and  Belle, respectively.  The new  collider will  start  its  commissioning  in  2015 .  This is an  am bitious project. The luminosity of the e + e – collider will be upgraded by  a factor of 40, which will create a 50  times larger data set compared to the Belle sample. Both the background and the triggered event rate s will be  increased by a factor of at least 10. The Belle II software system is designed to accommodate these challenges and  to run on grid, cloud, and local resources around the world. Various external software packages are  employed to  enhance the user  interface. The software system,  basf2 , is str uctured as a framework built with dynamic module  loading  and  the  ability  of  parallel  processing.  The  system  is  written  in  C++  with  Python  steering  sc ripts,  compatible with common  Linux operating systems. A full detector simulation library is created based on Geant4.  In this  paper , we will explain the design of th e Belle II software structure  and the current status of the software  development
