As a consequence of this research program, it became clearer that new physics such as supersymmetry could be investigated by increasing the luminosity of the B factory. Simulation studies were performed to investigate the experimental sensitivities to various theoretical predictions, and we found that the search for charged Higgs particle in B→Dτv decays with 5000fb^<-1> is equivalent to the direct search in LHC experiment with 100fb^<-1>. Also, the FCNC decays of B meson, B→K^*μμ, is found to be sensitive to the contribution of SUSY particles, if the forward-backward asymmetry is measured with 3000fb^<-1>. The research of the accelerator enabled us to identify the fundamental issues that have to be solved to design the storage ring to accumulate much higher beam current. Based on this result and the experience at the KEKB accelerator, it is concluded that a collider with the luminosity higher than 10^<35>. Also the research of the detector enabled us to identify the necessary R&D items to carry out an experiment at the higher luminosity beyond 10^<35>.
