  We study leptonic flavor and CP violating observables in supersymmetric
(SUSY) models with heavy sfermions, which is motivated by the recent results of
the LHC experiments (i.e., the discovery of the Higgs-like boson with the mass
of about 126 GeV and the negative searches for the superparticles). Even if the
sfermion masses are of O(10-100 TeV), signals may be within the reach of future
leptonic flavor- and CP-violation experiments assuming that the off-diagonal
elements of the sfermion mass matrices are unsuppressed compared to the
diagonal ones. We also consider the SUSY contribution to the K0-K0bar mixing
paraemters; we show that the leptonic observables can become as powerful as
those in K0-K0bar mixing to constrain SUSY models.
