Studied arethe integrable difference-difference equations for the lattice W currents, which can be regarded as the full-discretized (reduced) KP equations.We find explicit forms ofthe time-discretization for the lowest equations of the hierarchyby making use of the relation with the Bogoyavlensky lattice.
