  We propose a simple mechanism for stabilizing flavon fields with aligned
vacuum structure in models with discrete flavor symmetry. The basic idea is
that flavons are stabilized by the balance between the negative soft mass and
non-renormalizable terms in the potential. We explicitly discuss how our
mechanism works in $A_4$ flavor model, and show that the field content is
significantly simplified. It also works as a natural solution to the
cosmological domain wall problem.
