We study 't Hooft anomaly matching in lattice models with strong Yukawa ormulti-fermion interactions. Strong non-gauge interactions among the mirrorfermions in a vectorlike lattice gauge theory are introduced with the aim toobtain, in a strong-coupling symmetric phase, a long-distance unbroken gaugetheory with chiral fermions in a complex representation. We show how to useexact lattice chirality to analyze the anomaly matching conditions on chiralsymmetry current correlators at finite lattice spacing and volume. We perform aMonte Carlo study of the realization of anomaly matching in a toytwo-dimensional model with an anomalous mirror-fermion content at strong mirrorYukawa coupling. We show that 't Hooft anomaly matching is satisfied, in mostof the phase diagram, via the minimal solution in either the massless fermionor "Goldstone" mode, while in some cases there are extra massless vectorlikemirror fermions. The mirror spectrum at strong coupling is thus consistent withlong-distance unitarity. We discuss the implications of our results for futurestudies of the most interesting case of the decoupling of anomaly-freemirror-fermion sectors.
