Description
We present our results of charm physics in
$N_f=2+1$ lattice QCD. Our calculation is
performed on configurations generated
with Iwasaki gauge and the six stout smeared
$O(a)$-improved Wilson quark actions on a $96^4$ lattice
at $\beta=1.82$ ($a^{-1} = 2.3$ GeV) with the spatial
extent $L=8.1$ fm. The pion mass is almost physical
$m_\pi=145$~MeV. The relativistic heavy quark action
is utilized for the charm quark.
We exhibit the charmed spectrum and the charm
quark mass, focusing on stout smearing influence.
