  We propose a simple radiative neutrino mass scenario with a Dirac dark matter
candidate, which is minimally realized by a Z3 symmetry. We introduce two Dirac
neutrinos and two inert doublets. We demonstrate that the model has a large
allowed region that satisfies the constraints from neutrino oscillation data,
lepton flavor violations, direct/indirect detection of dark matter and dark
matter relic density. We also propose an efficient parameterization of the
neutrino Yukawa couplings, which reproduces a desired active neutrino mass
matrix.
