covert possessor raising in japanese

japanese has a set of idiomatic predicates that invoke possessor raising counting as a-movement. with the possessor-raising predicates, the possessor is overtly raised to spectp when it is marked with dative case. when the possessor receives nominal genitive case, it is located within the possessum nominal on the surface, and spectp is left unfilled. it is shown that the genitive possessor, which has remained in nominal-internal position in overt constituent structure, undergoes covert a-movement into spectp.
