We investigate the axial $U(1)$ symmetry in the phase above the critical temperature in $N_f=2$ lattice QCD, where the ensembles are generated with Mobius domain-wall fermions, and the overlap/domain-wall reweighting is applied. We show the $U(1)_A$ susceptibility extracted from the spectra of the overlap Dirac eigenmodes and discuss its temperature, quark-mass, and spatial volume dependence. The behavior of $U(1)_A$ susceptibility is compared with that of topological susceptibility and their relation is discussed.
