The hadronic light-by-light scattering contribution is one of the QCD contribution which could be significant to the muon g-2, but has been only estimated by the hadronic model calculation. The standard model prediction containing the result obtained as such disagrees with the experimental value of the muon g-2. Before concluding that this difference should come from the unknown structure not included in the standard model, it is quite important to calculate the hadronic light-by-light scattering contribution by the lattice QCD simulation. We demonstrated the feasibility of our method invented to simulate the contribution induced from the connected-type hadronic light-by-light scattering diagram, and reported the first lattice QCD result for this contribution.I also proposed one idea for the method that computes all contribution including disconnected-type diagrams.
