We generate 2+1 flavor QCD configurations near the physical point on a 964 lattice employing the 6-APE stout smeared Wilson clover action with a nonperturbative cSW and the Iwasaki gauge action at β=1.82. The physical point is estimated based on the chiral perturbation theory using several data points generated by the reweighting technique from the simulation point, wherer mπ,mK and mΩ are used as physical inputs. The physics results include the quark masses, the hadron spectrum, the pseudoscalar meson decay constants and nucleon sigma terms, using the nonperturbative renormalization factors evaluated with the Schrodinger functional method.
