  We discuss the sensitivity of the high-scale SUSY at $10$-$1000$ TeV in
$B^0$, $B_s$, $K^0$ and $D$ meson systems together with the neutron EDM and the
mercury EDM. In order to estimate the contribution of the squark flavor mixing
to these FCNCs,we calculate the squark mass spectrum, which is consistent with
the recent Higgs discovery. The SUSY contribution in $\epsilon_K$ could be
large, around 40% in the region of the SUSY scale $10$-$100$ TeV. The neutron
EDM and the mercury EDM are also sensitive to the SUSY contribution induced by
the gluino-squark interaction. The predicted EDMs are roughly proportional to
$|\epsilon_K^{\rm SUSY}|$. If the SUSY contribution is the level of O(10%) for
epsilon_K, the neutron EDM is expected to be discovered in the region of
$10^{-28}$-$10^{-26}$ecm. The mercury EDM also gives a strong constraint for
the gluino-squark interaction. The SUSY contribution of $\Delta M_D$ is also
discussed.
