In this paper, I investigate binding effects triggered by long-distance scrambling in Japanese. The first purpose of the study is to describe an environment where long-distance scrambling can feed A-binding and make a generalization about it. The generalization made in this paper is that Long-distance scrambling can feed A-binding only if i) the embedded subject is null, and ii) a bindee is contained in the matrix object (or in the matrix subject if there is no matrix indirect object). The second purpose is to give an analysis to derive the generalization without recourse to A/A'-distinction. As discussed in the paper, there are some problems in an approach to capture binding phenomena resorting to A/A'-distinction. Therefore, I propose an analysis to derive the generalization without using the notion of A/A'-distinction.
