The rational Kashiwara-Miwa model is an example of an Ising-type integrable model of the statistical physics, related to the six-vertex trigonometric R-matrix. Two-spin edge weights of the model are expressed in the terms of q-products, its spins are arbitrary integers, and |q|<1. We discuss in this paper the algebraic structures underlying the model, in particular its relation to the q-oscillator algebra, to representations of the q-oscillator algebra and to the co-product of the q-oscillator algebra.
