We study a way of coding of irrational rotations, by which Denjoy systems are represented as subshifts. First, we state the subshift generated by a coding sequence is conjugate to a Denjoy system. Next, by using an adic model of a Denjoy system we give a sequence of substitutions to generate the coding sequence.
