The Wilson chiral perturbation theory is applied to the pseudoscalar meson masses and the decay constants in 2+1 flavor lattice QCD with O(a)-improved Wilson quarks. We examine the existence of the chiral logs investigating the quark mass dependences from 6 MeV to 42 MeV in (3.2fm)3 box with the lattice spacing a=0.1fm. Some low energy constants are determined. We also discuss the finite size effects based on the chiral perturbation theory.
