  We study the (2+1)-flavor QCD at nonzero temperatures using nonperturbatively
improved Wilson quarks of the physical masses by the fixed scale approach. We
perform physical point simulations at finite temperatures with the coupling
parameters which were adopted by the PACS-CS Collaboration in their studies
using the reweighting technique. Zero temperature values are obtained on the
PACS-CS configurations which are open to the public on the ILDG/JLDG. Finite
temperature configurations are generated with the RHMC algorithm. The lattice
sizes are $32^3 \times N_t$ with $N_t=14$, 13, $\cdots$, 4 which correspond to
$T \approx 160$--550 MeV. We present results of some basic observables at these
temperatures and the status of our calculation of the equation of state.
