The purpose of this paper is to show that the syntactic structures of long-from causative constructions should be derived within the same clause projected by ‘-ke ha-.’ The previous studies suggest that the syntactic structures of long-from causative constructions be divided into two types: one is that the causees are positioned in the main clause and the other is that the causees are positioned in the embedded clause. However, in this paper it is pointed out that there are some problems with the studies and the causees in the constructions should be placed in the embedded clause.
