There are many new physics models for generating neutrino masses, and it is important to consider how these models can be experimentally discriminated. Classification of models is useful for the efficient discrimination. In this talk, we classify simple models for each of Majorana and Dirac neutrino masses into some groups by concentrating on Yukawa interactions with leptons. We see these groups of models can be tested by e.g. lepton flavor violating (LFV) decays of the tau lepton. In addition, if a LFV decay of the Higgs boson is discovered, simple models for Majorana neutrino masses are excluded while some models for Dirac neutrino masses can survive.
