There has been renewed interest in the nucleon sigma term - the scalar form factor of the nucleon at zero recoil - since it determines the dark matter reaction rate with nucleon through the t-channel Higgs boson exchange. Despite its importance and its long history of theoretical studies, there are still substantial uncertanties. We present our recent studies of the nucleon sigma term based on the JLQCD project of Nf=2 unquenched lattice QCD simulation with dynamical overlap fermion.
