I report recent developments on hadron interactions in lattice QCD by the HAL QCD method. As an introduction, I summarize the lattice community's consensus on the absence of the deeply bound dinucleons at heavier pion masses. We then present 4 results by the HAL QCD method using 2+1 flavor QCD gauge configurations at mπ≃ 146 MeV and a≃ 0.0846 fm, which are the ΛΛ-NΞ interactions, NΩ dibaryon, the tetra-quark state Tcc and the N-ϕ interaction with the 2-pion tail. A brief summary follows.
