The purpose of the talk is to introduce a new rephasing invariant
parametrization for the 3x3 CKM matrix and discuss the properties and
applications of the parametrization. The overall phase condition leads
this parametrization to have only six rephasing invariant parameters
and two constraints. Especially its simplicity and regularity become
apparently interesting when it is applied to the one-loop
renormalization group equations for the Yukawa couplings. The
implications of this parametrization for unification of the Yukawa
couplings are also considered.
