  We examine contributions from Majorana phases to lepton flavor violating
processes in the framework of the minimal supersymmetric standard model with
heavy right-handed neutrinos. All phases in the complex neutrino Yukawa matrix
are taken into account in our study. We find that in the scenario with
universal soft-breaking terms sizable phase effects can appear on the lepton
flavor violating processes such as $\mu \to e \gamma$, $\tau \to e \gamma$, and
$\tau \to \mu \gamma$. In particular, the branching ratio of $\mu \to e \gamma$
can be considerably enhanced due to the Majorana phases, so that it can be much
greater than that of $\tau \to \mu \gamma$.
