We explore multiple Right Dislocation in Japanese, which has previously received very little attention, and argue that it is derived not by syntactic movement but by Prosodic Right Dislocation in the phonological component. Evidence comes from multiple Right Dislocation's insensitivity to syntactic constraints, its lack of LF interpretive effects, and its prosodic properties. We propose the Universal Uniqueness Principle, arguing that phonological movement (Agbayani, Golston, and Ishii 2015) derives multiple movement constructions in Japanese. We advance the idea that the presence of so-called "uniqueness effects" in some languages and their absence in others (Fukui 1999/2006) fall out as a result of differences in their prosodic structures.
