  We propose a supersymmetric radiative seesaw model with modular $A_4$
symmetry. Thanks to contributions of supersymmetric partners to one-loop
diagrams generating neutrino masses, we successfully fit neutrino data and
obtain predictions in case of normal hierarchy in a minimal framework that
would not be realized in a non-supersymmetric model. We show a several
predictive figures and demonstrate a best fit benchmark point through $\chi^2$
