  A new yukawaon model is investigated under a family symmetry U(3)\times S_3.
In this model, all vacuum expectation values (VEVs) of the yukawaons, <Y_f>,
are described in terms of a fundamental VEV matrix <\Phi_0> as in the previous
yukawaon model, but the assignments of quantum number for fields are different
from the previous ones: the fundamental yukawaon \Phi_0 is assigned to (3,3) of
U(3) \times U(3), which is broken into (3,1+2) of U(3) \times S_3, although
quarks and leptons are still assigned to triplets of U(3) and yukawaons Y_f are
assigned to 6^* of U(3). Then, VEV relations among Yukawaons become more
concise considerably than the previous yukawaon models. By adjusting
parameters, we can fit not only quark mixing parameters but also lepton mixing
parameters together with their mass ratios.
