Abstract: We present a newly enhanced version of the Monte Carlo shell-model (MCSM) method by incor-
porating the conjugate gradient method and energy-variance extrapolation. This new method
enables us to perform large-scale shell-model calculations that the direct diagonalization method
cannot reach. This new-generation framework of the MCSM provides us with a powerful tool to
perform very advanced large-scale shell-model calculations on current massively parallel com-
puters such as the K computer. We discuss the validity of this method in ab initio calculations
of light nuclei, and propose a new method to describe the intrinsic wave function in terms of
the shell-model picture. We also apply this new MCSM to the study of neutron-rich Cr and Ni
isotopes using conventional shell-model calculations with an inert
