We propose that the TeV scale mirage mediation in the Next-to-Minimal
Supersymmetric Standard Model (NMSSM) is a novel solution for the little
hierarchy problem in supersymmetry. The 125 GeV Higgs boson can be accommodated
with the new quartic coupling or the mixing with the singlet. The fine-tuning
measures are estimated numerically and found as low as 10\% or below for $1.5$
TeV gluino and $1$ TeV stop. The higgsino can be as heavy as 500 GeV without
deteriorating the fine-tuning. An undesirable singlet-doublet mixing in the
Higgs sector is suppressed due to approximate scale symmetries. We investigate
the couplings of the Higgs bosons and discuss the prospects for studying them
at LHC and ILC.
