We present initial results of computing nucleon electric dipole moment induced by quark chromo- EDM, CP-violating quark-gluon coupling. Using chirally-symmetric domain wall and Möbius fermions with pion mass m\pi = 172 MeV, we calculate the connected part of the electric dipole form factor F_3(Q^2). In addition, we perform an exploratory study of the method to calculate EDM using uniform background electric field on a lattice introduced without breaking the periodicity in the time direction.
