In this paper, I will present two proposals. First, I propose that sika-nai constructions in Japanese should be analyzed in the same way as exception conjunctions in English, paying attention to the fact that NPs followed by sika can occur with additional NPs with a Case-particle. A motivation for my proposal comes from some semantic similarities between sika-nai constructions and exception conjunctions. Further, I will argue that additional NPs move to sika NPs for getting an appropriate interpretation at LF, along the line of Reinhart's (1991) analysis that a correlate moves to an except phrase for an interpretation, contrary to the recent minimalist assumption that movement is driven by some morphological features
