We first introduced a brief framework of Recursive Categorical Syntax to familiarize the reader with the theory. Following the spirit of the theory, we have analyzed some binding structures in English and Japanese. We have chosen question, relative, focus, and topic constructions as representatives. In the course of our discussion, it was shown that unlike English the Japanese question we dealt with are not instances of binding. The rest of the Japanese examples are indeed instances of binding just like their English conterparts as we have seen.
