Being inspired by a phenomenological success of a charged lepton mass formula, a model with U(3)-family nonet Higgs bosons is proposed. Here, the Higgs bosons ϕL (ϕR) couple only between light fermions (quarks and leptons) fL (fR) and super-heavy vector-like fermions FR (FL), so that the model leads to a seesaw-type mass matrix Mf≃ mL MF-1 mR for quarks and leptons f=u,d,ν and e. Lower bounds of the physical Higgs boson masses are deduced from the present experimental data and possible new physics from the present scenario is speculated.
