Nuclear forces and hyperon forces are studied by lattice QCD. Simulations are performed with (almost) physical quark masses, mπ ≃ 146 MeV and mK ≃ 525 MeV, where Nf = 2+1 nonper- turbatively O(a)-improvedWilson quark action with stout smearing and Iwasaki gauge action are employed on the lattice of (96a)4 ≃ (8:1fm)4 with a-1 ≃ 2:3 GeV. In this report, we give the overview of the theoretical framework and present the numerical results for two-nucleon forces (S = 0) and two-Ξ forces (S = -4). Central forces are studied in 1S0 channel, and central and tensor forces are obtained in 3S1-3D1 coupled channel analy.
