We study a supersymmetric model in which the Higgs mass, the muon anomalousmagnetic moment and the dark matter are simultaneously explained with extravector-like generation multiplets. For the explanations, non-trivial flavorstructures and a singlet field are required. In this paper, we study the flavortexture by using the Froggatt-Nielsen mechanism, and then find realistic flavorstructures which reproduce the Cabbibo-Kobayashi-Maskawa matrix and fermionmasses at low energy. Furthermore, we find that the fermion component of thesinglet field becomes a good candidate of dark matter. In our model, flavorphysics and dark matter are explained with moderate size couplings throughrenormalization group flows, and the presence of dark matter supports theexistence of just three generations in low energy scales. We analyze theparameter region where the current thermal relic abundance of dark matter, theHiggs boson mass and the muon $g-2$ can be explained simultaneously.
