We prove a forward Ergodic Closing Lemma for nonsingular $C^1$ endomorphisms, claiming that the set of eventually strongly closable points is a total probability set. The "forward" means that the closing perturbation is involved along a finite part of the forward orbit of a point in a total probability set, which is the same perturbation as in Mañé's Ergodic Closing Lemma for $C^1$ diffeomorphisms. As an application, Shub's Entropy Conjecture for nonsingular $C^1$ endomorphisms away from homoclinic tangencies is proved, extending the result for $C^1$ diffeomorphisms by Liao, Viana and Yang.
