  The energy-momentum tensor and equation of state are studied in
finite-temperature (2+1)-flavor QCD with improved Wilson quarks using the
method proposed by Makino and Suzuki based on the gradient flow. We find that
the results of the gradient flow are consistent with the previous results using
the $T$-integration method at $T \mathrel{\rlap{\raise 0.511ex
\hbox{$<$}}{\lower 0.511ex \hbox{$\sim$}}} 280$ MeV ($N_t\mathrel{\rlap{\raise
0.511ex \hbox{$>$}}{\lower 0.511ex \hbox{$\sim$}}}10$), while a disagreement is
found at $T \mathrel{\rlap{\raise 0.511ex \hbox{$>$}}{\lower 0.511ex
\hbox{$\sim$}}} 350$ MeV ($N_t \mathrel{\rlap{\raise 0.511ex \hbox{$<$}}{\lower
0.511ex \hbox{$\sim$}}} 8$) presumably due to the small-$N_t$ lattice artifact.
We also report on the results on the renormalized chiral condensate and its
disconnected susceptibility using the method of Hieda and Suzuki. The results
show a clear signal of the expected chiral restoration crossover even with
Wilson-type quarks which violate the chiral symmetry explicitly.
