I will present an overview as to how the structure of exotic nuclei changes
as a function of the neutron number (i.e., the distance from the beta stability
line), in comparison to stable nuclei, as consequences of particular components
of nuclear forces.  The discussions will be kept as basic as possible.  These
components include central, tensor, spin-orbit and three-body forces. They
produce characteristic effects, some of which can be considered to be paradigm
shifts (from the common sense of stable nuclei).  These changes become visible
as the shell evolution, but also can be seen in nuclear shapes, for example, in
the form of the shape evolution and the shape coexistence.  I will point out that
Landau’s quantum liquid picture on nuclear structure gains a new aspect in
exotic nuclei also due to proton and neutron composition of nuclei. Thanks to
developments of RI beam facilities worldwide including RIBF, various new
features connected to those evolutions have been observed.  I will touch on
calculations of physical observables, including recent developments made by
Tokyo shell-model group, for instance, with the Monte Carlo Shell Model and
the K-computer.  I will comment that these developments have applications
to other fields of science like double-beta decay and nuclear transmutation.
