  Rare decays of B and K mesons and CP violations thereof are considered in
SUSY models with S_3^3 flavor symmetry. SUSY contributions to epsilon_K and
epsilon'/epsilon_K can be large, but not to B0 - B0 bar mixing because of
strong constraint from B -> X_d gamma for (delta^d_{13})_{LR}. Still large
deviations from the SM predictions are possible in the branching ratio for B ->
X_d gamma and direct CP violations therein, even if the KM angle gamma is in
the range preferred by the SM CKM fit. Experimental study of B -> X_d gamma is
strongly recommended as a probe for new physics with nontrivial flavor
structure in the (13) mixing.
