  We study one-loop induced radiative seesaw model applying a modular $A_4$
flavor symmetry, in which the neutrino mass matrix is achieved by two different
Yukawa couplings one of which also contributes to positive value of muon
anomalous magnetic moment as well as lepton flavor violations. Thanks to the
specific mass matrix via $A_4$ symmetry and its modular weight, we find several
predictions for lepton sector through our numerical analysis.
